Background
In the whole body medical image examination equipment, for example, when a chest film is shot and X-rays are shot by four limbs, a light beam device can be seen, and the function of contracting light beams is achieved as the name suggests. The actual effect is that firstly, the lamp on the beam splitter is turned on, and the X, Y two-direction knobs of the beam splitter are adjusted, so that the light of the beam splitter irradiates on the film box of the machine, the size of the light field is just consistent with that of the film, and then the film can be shot.
The X-ray field and the light field are adjusted to have extremely small deviation, and the light field plays a role in simulating the invisible X-ray field. In the field of medical imaging of oral, jaw and face, the technical method is lacked, especially on the most widely used clinical X-ray dental film machine.
The two existing technologies are angular bisector projection technologies, one is the angular bisector projection technology, the angular bisector projection technology is the most common projection technology in clinic, and the angular bisector is established theoretically, but because the central line of the X line is not perpendicular to the tooth long axis and the film (image imaging plate) during projection, the direction of the central line of the X line is adjusted according to an imaginary angular bisector, which is often inaccurate, the photographed tooth image is often distorted and deformed, and how to determine the specific spatial position of the angular bisector is fuzzy and can not be determined; when projection is carried out in the projection direction and fixed-point positioning, the textbook edition and the national standard reference are body surface marks of soft tissues of the face of a patient, and obviously, too many suspicious points and uncertainties are marked on the external body surface of a photographed tooth X-ray image. The X-ray centerline should be as parallel as possible to the tangent of the adjacent surface of the tooth being examined. The word "try best" in the above description is used for its confusion and inaccuracy. Too much fault-tolerant space also exists in the projection process. The other is a parallel projection technology, when the parallel projection technology is adopted, the central line of an X-ray is vertical to the surface of the film, and is not vertical to an imaginary line any more than the angular line technology, so the technology is easy to ensure. However, the parallel projection technique is also theoretically perfect, is very ineffectual in implementation, is limited by the size of the oral cavity of the patient, cannot be operated, and in most cases, theoretically reaches the point that the image plate is parallel to the long axis of the tooth, and the position of the image plate at the moment is wandering out of the oral cavity. The two technical systems have rationality on the projection principle, but have too much uncertainty on the actual operation of fixed-point positioning.
Therefore, those skilled in the art have been devoted to developing an X-ray beam unit for a dental machine, which can reduce the radiation according to the irradiation area, more precisely project the irradiation area, reduce the extra irradiation to avoid the non-inspection area, reduce the radiation dose of the patient, and enhance the image quality.
