In particular, during routine health examinations and medical examinations, X-ray radiographs are often used to determine the cardiopulmonary structure and function of a subject. With the increasing demand for radiographic examinations in clinical or physical examination centers, hundreds of radiographic examinations are performed by each imaging technician each day, which makes the imaging examination work increasingly burdensome.
The radiographic process is similar to the traditional radiographic process, and is a cooperative process among three parties including a photographic apparatus, a photographer and a subject, and a medical imaging technician needs to guide and assist the subject to perform correct positioning and exposure setting like the photographer to obtain a final effective X-ray image, so that the method is low in efficiency. The auto-shooting function of the current novel photographic equipment (such as smart phones) simplifies the traditional photographic process into the relation between the photographic equipment and the object to be shot, and people are trying to realize the automatic radiographic process by using the advanced technology in consideration of the similarity of the radiographic inspection process and the photographic process.
In the process of radiography, firstly, the central line of X-ray is required to be aligned to the center of a shot human body and the center of an X-ray receiving unit, then the irradiation field of the X-ray is adjusted through a beam light device to cover all the region of interest, and finally, the radiation projection image of the X-ray penetrating through the human body is obtained through exposure and fluoroscopy. In order to relieve the work pressure of radiological imaging technicians, siemens and other well-known imaging equipment manufacturing companies have developed automatic radiography devices that enable highly sophisticated examinations to be performed with high quality. However, these high-end inspection devices are designed to meet the requirement of special X-ray film inspection in radiology department, and the whole device is bulky, has many operation procedures, and needs to be monitored and used by professionals, so the film-taking efficiency is not high.
