By setting the fixing member 27, the body position of the patient can be fixed to prevent the patient from disturbing the treatment accuracy; by setting the armrest 28, while further fixing, the patient can get out of bed by holding the armrest 28 after the treatment is completed.

In another embodiment, the top support surface of the treatment couch body 10 is provided with a chute or a guide rail, and the support bracket 20 is adapted and connected to the chute or the guide rail through a sliding member provided at the bottom of the support bracket 20 . By arranging the chute or guide rail and the corresponding sliding member, the supporting bracket 20 can be moved as a whole to the top of the bed board 11 after changing from the sitting position to the sleeping position, and the supporting effect is better. Optionally, the support bracket 20 can also be driven to move along the guide rail or the chute by means of hydraulic pressure, pneumatic force or ball screw. Of course, a roller can also be provided at the bottom of the support bracket 20, and the roller can be driven by a motor to drive the support. The bracket 20 moves along the guide rail or the chute, but the present invention is not limited to this. In FIG.

One aspect of the present invention provides a radiotherapy positioning system, comprising a radiotherapy machine, a data collection device, a data processor, a controller, and an adjustable radiotherapy couch as described above, the data collection device being used for collecting The height data of the lifting block 21 and the position data of the treatment couch and the collected data are transmitted to the data processor, which is used for receiving, storing and processing the obtained data, and the controller is used for Corresponding data in the data processor is acquired, and the controller controls the lifting block 21 to reach a preset height and controls the radiotherapy couch to reach a preset position through the driving structure 30 . For example, data collection devices may include distance sensors, displacement sensors, and the like. For example, the controller can control the movement of the drive structure 30 by converting the data into a corresponding program, and can also manually adjust the height data of the lifting block 21 and the position data of the treatment couch recorded, both of which are in the prior art. Not limited to this. By setting the radiotherapy positioning system, the body position data (height data and the position data of the treatment couch) of the patient during the first radiotherapy can be recorded and stored. When the next radiotherapy is performed, the corresponding stored data can be adjusted by the controller. Taking and forming a corresponding control program to control the driving structure 30, so that the lifting block 21 reaches the preset height and the treatment couch reaches the preset position, which effectively reduces the time used in the non-treatment stage of radiotherapy and saves time and cost.

In a further embodiment, the scanning system of the radiotherapy machine is connected to the data processor and used to update the corresponding data of the data processor. For example, after the position is adjusted, a CBCT scan can be performed to verify the patient's position. If there is a registration error, the error value can also be sent to the treatment couch or a data processor for bed movement correction. When the patient is being treated, if the data from the previous treatment is found to be inappropriate, the patient will be positioned and data formed by the scanning system of the radiotherapy machine, and the data processor will be effectively realized by connecting the scanning system with the data processor. Update the data in , so that the latest postural data can be used for subsequent radiation therapy.

In another embodiment, it also includes an image recognition device located above the treatment table and connected to the radiotherapy machine, the image recognition device is used for recognizing the lead beads marked on the human body and transmitting the position data of the human body to the data processor for updating the corresponding personal data. For example, on the roof of the radiotherapy machine, with the central treatment point of the radiotherapy accelerator as the center, a high-definition camera is installed at 45° and 315° in the rotation plane of the radiotherapy machine. Roughly determine the part of the radiotherapy patient that needs radiotherapy, and print as many reference points on the body surface as needed (generally more than 3), and paste special lead beads (easy to be identified by high-definition cameras) at the reference point. CT positioning, the camera detects the position of the lead bead, and records the position information of the lead bead and the position information of the treatment bed in this state. By setting the image recognition device to correspond to the lead beads of the human body, the patient's body position data is further clarified, which is used to update the corresponding personal data, so that the latest body position data can be used in subsequent radiotherapy.

In this specific example, when the patient needs radiation therapy, at the end of the treatment couch, the patient is first seated at the hip support 25 of the treatment couch. The fingerprint identification device on the treatment bed collects the patient's fingerprint) to identify the patient's physiological characteristics. After the identification is successful, each module of the treatment bed is automatically adjusted to a mode suitable for the patient's sleeping position. The patient holds the armrest or lies on the treatment bed with the assistance of the doctor. The bracket 24 is automatically transformed into a straight state, and each part of the support bracket 20 automatically enters the upper position of the treatment couch body 10. According to the part where the patient needs radiotherapy, the doctor adjusts the position of the treatment couch body 10, and at the same time, by manipulating the driving structure 30.
