Description
Technical Field
The invention relates to the technical field of digital X-ray machines, in particular to a portable digital X-ray machine.
Background
Direct Digital flat Panel X-ray imaging system (Director Digital Panel radiation DDR). Is a brand new digital imaging technology developed in recent years. The successful development and clinical application of the flat-panel digital detector are a leap in the imaging technology; the principle is that after X-rays penetrate through a human body, the X-rays are attenuated to different degrees and act on an amorphous silicon or amorphous selenium array plate on a digital flat plate, and due to the fact that the strength of the X-rays is different, a selenium or silicon surface layer light conductor generates an electric field which is generated between an electrode on the top layer of an electron positive hole pair (electron positive layer) and a current collection matrix and is generated on a silicon layer according to the strength of absorbed X-ray energy, positive charges generated by the X-rays are separated, the positive charges move to the current collection matrix and reach a capacitor stored in a thin film transistor, charges stored in the capacitor of the matrix are in direct proportion to an X-ray image, then a scanning controller reads a circuit to convert photoelectric signals into digital signals, and digitized image data are stored and processed in a collection workstation. The image is displayed on an image monitor, and the image acquisition and processing are completely automatic under the control of a computer, and comprise the processes of image selection, image correction, noise processing, dynamic range, gray scale reconstruction, output matching and the like. After the above process is completed, the scanning controller automatically recovers the sensing medium in the acquisition board, and the whole process is about 10 seconds.
Because the tissues such as bones and muscles of the human body are different, the X-ray quantity absorbed when the X-ray passes through the human body is also different, the density information of each part of the human body carried by the X-ray is also different, and each projection system of the direct digital X-ray photography system comprises all projection positions. The DR system uses high-voltage low-current automatic ionization chamber photography under the initial condition according to different X-ray absorption rates, and can clearly show the fine structure of each anatomical part due to high spatial resolution, time resolution and large dynamic range, and can process images under various set modes due to the powerful image post-processing function, so that clear and perfect images with high contrast can be obtained, and the clinical diagnosis level is greatly improved. At present, the application of DR in clinical diagnosis is very popular, and makes great contribution to doctors to accurately understand the illness state of patients and make treatment plans. However, with the continuous progress of science and technology and society, people have higher requirements on DR and images.
At present, the traditional DR shooting needs a fixed field (lead room), the radiation dose is high, secondary damage is caused by scattered rays during shooting, the structure is complex, and the size is huge and heavy; for children and teenagers, the radiation dose is high, and the injury is large.
In order to solve the above problems, a portable digital X-ray machine is proposed in the present application.
