It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a flowchart illustrating a method for capturing a medical image in an embodiment, and in an embodiment, as shown in fig. 1, a method for capturing a medical image is applied to a medical imaging system for performing X-ray panoramic image capturing on a portion to be captured of the same imaging object, and includes the following steps:

Specifically, when the part to be shot of the imaging object is shot by the X-ray panoramic image, if the imaging object shoots the panoramic image on the same part once, the shooting record shot last time can be automatically obtained, the shooting starting point and the shooting end point are stored in the shooting record, after the shooting starting point and the shooting end point are determined, the imaging object is shot by the X-ray from the starting point to the end point for multiple times, so that the range of the part to be shot is completely shot, and the X-ray panoramic image of the part to be shot is obtained.
The shooting record can be obtained from local shooting historical data of a medical image system, and can also be obtained from a case database through networking, so that the shooting of a panoramic image of a part to be shot of an imaging object is realized, namely, the positioning of a shooting starting point and a shooting end point is not needed to be carried out again.
Further, the method for capturing medical images is applied to the medical imaging system 200 for capturing an X-ray panoramic image of a portion to be captured of the same imaging object, as shown in fig. 2, the medical imaging system 200 includes a bracket 212, a column 222, a flat panel detector 224, an X-ray generating device 232, a hanging bracket 234 and a processor (not shown), the bracket 212 faces the X-ray generating device 232, the X-ray generating device 232 is disposed on a wall through the hanging bracket 234, the flat panel detector 224 is disposed adjacent to and behind the bracket 212, and the flat panel detector 224 is movably disposed on the column 222. It is understood that, in addition to the X-ray generating device 232 provided on the hanger 234 in the present embodiment, other types of X-ray generating devices such as a floor-type X-ray generating device and the like are also applicable to the above-described imaging method.
When the part to be shot of the imaging object is shot, the imaging object stands on the support 212, the processor inquires whether shooting records of an X-ray panoramic image of the part to be shot of the imaging object are stored in the system, if the shooting records of the part to be shot are stored, a shooting start point and a shooting end point are automatically obtained according to the shooting records, the angle of the X-ray generating device 232 is adjusted according to the position of the shooting start point, the ball tube in the X-ray generating device 232 emits X-rays, the flat panel detector 224 receives the X-rays penetrating through the imaging object for imaging, after one image is shot, the angle of the X-ray generating device 232 is continuously adjusted, meanwhile, the flat panel detector 224 synchronously moves to a target position on the stand 222 for shooting a second image until the whole area of the part to be shot is shot, and shooting of the panoramic image of the part to be shot is completed.
According to the method for shooting the medical images, the starting point and the end point of the panoramic image shooting are automatically obtained by utilizing the shooting record, the starting point and the end point do not need to be determined again when the part to be shot of the same patient is shot for the non-first time or shot in different positions, the shooting process is effectively simplified, and the time for keeping the position of the patient in the X-ray panoramic image shooting process is reduced.
In an embodiment, after step S104, the method for capturing a medical image further includes:
step S106: and splicing the images acquired by multiple times of X-ray shooting to obtain a panoramic image of the part to be shot.
Specifically, after a part to be shot is shot by X-rays for multiple times from a starting point to an end point, all areas of the part to be shot are shot to obtain multiple images between the starting point and the end point, and the multiple images are spliced by a computer and other equipment to obtain a complete image of the part to be shot from the starting point to the end point, namely an X-ray panoramic image of the part to be shot.
Fig. 3 is a flowchart illustrating a method of capturing a medical image according to another embodiment, and in one embodiment, as shown in fig. 3, a method of capturing a medical image includes the following steps:
step S302: when the shooting record of the part to be shot is not stored in the medical imaging system, the shooting range of the part to be shot is acquired.
Specifically, if the medical imaging system does not store a shooting record of an X-ray panoramic image of a to-be-shot part of an imaging object, for example, the imaging object has not been subjected to X-ray shooting or has not been stored in previous shooting, a shooting range of the to-be-shot part of the imaging object is obtained, where the shooting range is determined by the to-be-shot part and physical characteristics of the imaging object, the specific shooting range may be manually input into the medical imaging system by a doctor or an operator, or may be obtained by reading medical record information and the like of the imaging object by the medical imaging system, and the specific shooting range may be the same as an area of the to-be-shot part, or may be slightly larger than the area of the to-be-shot part to reserve a certain imaging margin.
Step S304: and determining a starting point and an end point of panoramic image shooting according to the shooting range.
Specifically, after the area range of the part to be shot of the imaging object on the body of the imaging object is obtained, the starting point and the end point of the panoramic image shooting can be calculated according to the area range of the shooting part, the starting point and the end point can be calculated by a computer according to the shooting range, and can also be manually set by a doctor or an operator, the starting point and the end point are determined according to the shooting range, the shooting range of an X-ray generating device is also considered, and the reasonable starting point and the reasonable end point are determined.
Step S306: and carrying out X-ray shooting on the part to be shot for multiple times according to the starting point and the end point.
Specifically, after a starting point and an end point of shooting are determined according to a shooting range of a part to be shot, the angle of the X-ray generating device can be adjusted, so that the edge of an X-ray coverage range sent by a bulb tube in the X-ray generating device reaches the position of the shooting starting point, the flat panel detector receives X-rays passing through an imaging object for imaging, after one image is shot, the angle of the X-ray generating device is continuously adjusted, meanwhile, the flat panel detector synchronously moves to a target position on a stand to shoot a second image, then shooting is carried out for multiple times until the shooting end point is reached, the whole area of the part to be shot is shot, then, the obtained multiple images can be spliced, and the shooting process of the whole panoramic image is completed.
Step S308: and storing the starting point and the end point of the panoramic image shooting of the part to be shot in the medical image system as shooting records.
Specifically, after the panoramic image shooting process is completed, the information of the part to be shot of the imaging object, the starting point and the end point of shooting and other data of the imaging object are stored in the medical image system, so that if the imaging object shoots the part again, the shooting record can be automatically inquired, the starting point and the end point of shooting can be obtained according to the shooting record, and the positioning process of shooting the starting point and the end point of the panoramic image again is omitted.
In one embodiment, before performing X-ray imaging on a region to be imaged a plurality of times according to a start point and an end point, the method further includes:
simulating panoramic image shooting according to the starting point and the end point;
and correcting the starting point and the end point of the panoramic image shooting under the condition that the positions of the starting point and the end point of the simulation do not meet the requirement.
Specifically, in the case where, for example, the imaging subject changes in stature from the time of the last shooting, or the like, a deviation may occur in the shooting start and end positions acquired from the shooting record. Therefore, in order to avoid error shooting, before X-ray shooting is carried out, the starting point position and the end point position can be simulated and displayed to a doctor or an operator for confirmation, if the starting point position and the end point position meet the actual shooting requirement, shooting is continued, and if the starting point position and the end point position do not meet the actual shooting requirement, the doctor and the operator can adjust or correct the starting point position and the end point position, so that the starting point position and the end point position of panoramic image shooting are more accurate.
Furthermore, in order to facilitate the simulation shooting operation of a doctor or an operator, a simulation button can be arranged on a control interface of the medical imaging system, after the simulation is started, the height, the angle and the like of the X-ray generating device are automatically adjusted according to the starting point and the end point, then the starting point of the shooting is indicated through the upper edge of the light field of the beam limiter, the end point of the shooting is indicated through the lower edge of the light field, the flat panel detector or the chest radiography box does not need to move in the process, and the doctor or the operator confirms the shooting or the adjustment of the position of the starting point and the end point according to the shooting range indicated by the light field of the beam limiter. It is to be understood that, in addition to the light field by the beam limiter, the start and end positions may be indicated by other means such as a laser pointer or the like to perform simulation of panoramic image photographing.
Fig. 4 is a partial flow diagram illustrating a method for capturing medical images according to an embodiment, in which, as shown in fig. 4, after a plurality of X-ray captures are performed on a region to be captured according to a start point and an end point, the method further includes:
step S402: judging whether the part to be shot needs to be shot by other positioning panoramic images or not;
step S404: automatically acquiring a starting point and an end point of panoramic image shooting under the condition that the part to be shot needs to be shot with other positioning panoramic images;
step S406: after the imaging object is ready for other positioning, the part to be shot is shot by X rays for multiple times according to the starting point and the end point.
Specifically, after a part to be shot of an imaging object is shot once, whether the part needs to be shot of panoramic images of other positions is judged, the judgment can be manually selected and confirmed by a doctor or an operator, the judgment can also be automatically determined according to medical record information and other conditions of the imaging object, under the condition that multiple times of panoramic image shooting of different positions needs to be carried out on the part to be shot, the starting point and the end point of the first position shooting can be automatically obtained, the starting point and the end point of the first position shooting can be utilized in subsequent position shooting, the shooting process is simplified, the starting point and the end point of the shooting do not need to be positioned for each position, and the time for keeping the position of the imaging object is reduced.
Fig. 5 is a flowchart illustrating a method for capturing a medical image according to an embodiment, as shown in fig. 5, in an embodiment, the method specifically includes the following steps:
step S502: and judging whether the shooting record of the part to be shot is stored in the medical image system.
Specifically, when an X-ray panoramic image is taken of an imaging object, a part to be taken is firstly confirmed, generally, a part with a large range such as a chest cavity or a lower limb which needs to be taken of the panoramic image is taken, after the part to be taken is confirmed, whether the imaging object takes the X-ray panoramic image of the part is inquired, if the part to be taken is taken, a shooting record of the last shooting is obtained, and the step S504 is entered, if the shooting record of the part to be taken of the imaging object is not stored in the medical imaging system, the step S506 is entered.
Step S504: and acquiring a starting point and an end point of panoramic image shooting according to the shooting record of the part to be shot.
Specifically, after a shooting record of a part to be shot stored in the medical imaging system is searched, patient information of an imaging object, history data for performing X-ray panoramic image shooting, and the like are stored in the shooting record, start point and end point position information of panoramic image shooting is acquired from the shooting record, and then the process proceeds to step S508.
Step S506: and acquiring the shooting range of the part to be shot, and determining the starting point and the end point of the panoramic image shooting according to the shooting range.
Specifically, if there is no shooting record of the part to be shot in the medical imaging system, which indicates that the imaging subject may be performing X-ray panoramic image shooting on the part for the first time, a shooting range of the part to be shot of the imaging subject is obtained, the shooting range may be manually input into the system by a doctor, and position information of the part to be shot on the body of the imaging subject may be calculated according to the shooting range of the part to be shot of the imaging subject, so that the shooting range of the panoramic image may be determined, and start point and end point position information of the panoramic image shooting may be obtained, and then the process proceeds to step S508.
Step S508: and simulating panoramic image shooting according to the starting point and the end point.
Specifically, after the start point and end point position information of the panoramic image shot in step S504 or step S506 is acquired, in order to ensure the accuracy of the shooting range and prevent the shooting range from deviating from the actual shooting requirement due to the change of the figure or the special figure of the shooting object, the panoramic image shot is simulated through the light field of the beam limiter, the start point and the end point position are indicated, and the doctor or the operator confirms the panoramic image shot.
Step S510: and judging whether the positions of the starting point and the end point of the simulation meet the shooting requirement.
Specifically, after confirming the doctor or the operator after indicating the start point and the end point of the photographing in step S508, the doctor or the operator proceeds to step S512 if the doctor or the operator considers that the start point and the end point of the simulation instruction do not meet the requirement of the actual photographing, and proceeds to step S514 if the doctor or the operator considers that the start point and the end point of the simulation instruction meet the requirement of the actual photographing.
Step S512: the start point and the end point of the panoramic image photographing are corrected.
Specifically, if the positions of the start point and the end point indicated by the analog shooting do not meet the requirement of the actual shooting, the positions of the start point and the end point can be adjusted and corrected, a doctor or an operator can manually adjust the light field irradiation range of the beam limiter to determine a new shooting start point and end point, or can remotely control or enable the system to automatically correct the positions of the start point and the end point so as to meet the requirement of the actual shooting, and the step S514 is executed after the positions of the start point and the end point are corrected.
Step S514: and carrying out X-ray shooting on the part to be shot for multiple times according to the starting point and the end point.
Specifically, after the positions of the starting point and the end point are determined to meet the actual shooting requirements, the X-ray imaging device is controlled to shoot a panoramic image of the part to be shot of the imaging object according to the starting point and the end point, the part to be shot is shot for multiple times from the starting point to the end point, multiple partial area images of the part to be shot are obtained to be spliced to obtain the panoramic image, and the step S516 is executed after the multiple times of shooting are finished.
Step S516: and storing the starting point and the end point of the panoramic image shooting of the part to be shot in the medical image system as shooting records.
Specifically, after the panoramic image of the part to be photographed is photographed, data such as patient information of the imaging subject, positioning information of the panoramic image photographing, and position information of a start point and an end point of the photographing are stored in the medical imaging system as photographing records, so that the start point and the end point of the panoramic image photographing are automatically acquired when the part is subjected to the X-ray panoramic image photographing again after the imaging subject. Since it is often necessary to photograph panoramic images of different placements on the same site in actual panoramic image photographing, the process proceeds to step S518 after storing a photographing record of this panoramic image photographing.
Step S518: and judging whether the part to be shot needs to be shot by X-ray panoramic images of other positions.
Specifically, after completing the panoramic image shooting of one position of the part to be shot, it is determined whether the part needs to be subjected to the panoramic image shooting of other positions, for example, after completing the normal position splicing of the part to be shot of the imaging object, it is determined whether the part needs to be subjected to the side panoramic image shooting. If it is determined that the panoramic image photographing of the other parking positions is necessary, the process proceeds to step S520, and if it is determined that the panoramic image photographing of the other parking positions is unnecessary, the process proceeds to step S522.
Step S520: and automatically acquiring a starting point and an end point of panoramic image shooting, and carrying out X-ray panoramic image shooting of other positions of the part to be shot.
Specifically, if it is determined that a plurality of positions are required to be shot at a position to be shot, after the shooting at a first position is completed, the next position is shot, for the shooting at a second position, the position information of the starting point and the end point of the shooting at the first position is automatically obtained, after no problem exists in the position of the imaging object, the X-ray imaging device is controlled to shoot the panoramic image at the second position at the position to be shot, after the shooting at the second position is completed, whether the panoramic image shooting at other positions is required is continuously judged, if necessary, the shooting at the starting point and the end point of the first shooting is continuously performed, and the step S522 is performed until all the panoramic images required to be shot are shot.
Step S522: the X-ray panoramic image photographing is ended.
Specifically, if the part to be photographed only needs to be subjected to one-position panoramic image photographing or the whole-position panoramic image photographing required by the part to be photographed is completed, the obtained multiple images are spliced to obtain a complete X-ray panoramic image of the part to be photographed, so that the X-ray panoramic image photographing process is finished.
