Description
Translated fromChinese技术领域technical field
本发明涉及口腔颌面部影像技术领域，尤其涉及一种X射线牙片机外置式束光器及使用方法。The invention relates to the technical field of oral and maxillofacial imaging, in particular to an external beamer of an X-ray dental tablet machine and a method for using the same.
背景技术Background technique
全身医学影像检查设备中比如胸片拍摄、四肢拍摄X光时，均可见束光器，顾名思义就是起到收缩光束的作用。实际作用就是首先打开束光器上的灯，并调节束光器的X、Y两个方向的旋钮，使束光器的光线照射到机器的片盒上，使光域或光野的大小刚好与胶片大小一致，然后就可以拍片。In whole-body medical imaging equipment, such as chest X-rays and X-rays of limbs, beams are visible, which, as the name suggests, functions to shrink the beam. The actual function is to first turn on the light on the beamer, and adjust the knobs in the X and Y directions of the beamer, so that the light of the beamer shines on the film box of the machine, so that the size of the light field or light field is just the same as the size of the light field. The film is the same size, and then you can shoot.
把X射线野和光域调整到偏差极小，这个光域就起到了模拟不可见X射线野的作用。而口腔颌面部医学影像领域中，尤其对临床最为广泛使用的X射线牙片机上，缺失此项技术方法。Adjusting the X-ray field and the light field to a very small deviation, this light field plays the role of simulating the invisible X-ray field. In the field of oral and maxillofacial medical imaging, especially in the most widely used clinical X-ray dental machine, this technical method is missing.
现有技术有两种，一种是角平分线投照技术，角平分线投照技术是临床上最为常用的投照技术，角平分线在理论上是成立的，但由于投照时X线中心线与牙长轴和胶片(影像成像板)不垂直，而是根据一条假想的角平分线来调整X线中心线的方向，往往不够准确，拍摄出的牙齿图像往往失真变形，主要如何确立角平分线的具体空间位置是模糊和无法测定的；在投照方向及定点定位投照时，教科书版及国家标准参照是患者面部软组织的体表标志，显然拍照的牙齿X线图像用外在的体表标记有太多的可疑点和不确定性。X射线中心线应尽量与被检查牙的邻面切线平行。其中的“尽量”一词，可见其疑惑与不精确性。投照过程中也存在着太大的容错空间。另一种是平行投照技术，采用平行投照技术时，X线中心线与胶片表面垂直，较分角线技术不再是假想的线垂直，因此，在技术上容易得到保证。但平行投照技术也同样存在理论上的完美，在执行上的很多无奈，受限于患者的口腔容积大小，无法操作，绝大多数情况，在理论上能达到影像板与牙齿长轴平行时，此时的影像板位置已经游弋出口腔外。两套技术体系，在投照原理上存在合理性，但定点定位在实操上太多的不确定性。There are two existing technologies, one is the angle bisector projection technology. The angle bisector projection technology is the most commonly used clinical projection technology. The angle bisector is theoretically established. The center line is not perpendicular to the tooth long axis and the film (image imaging plate), but adjusts the direction of the X-ray center line according to an imaginary angle bisector, which is often inaccurate, and the photographed tooth images are often distorted and deformed. The specific spatial position of the angle bisector is ambiguous and undeterminable; in the projection direction and fixed-point positioning projection, the textbook version and the national standard reference are the body surface markers of the patient's facial soft tissue, obviously the dental X-ray images are taken with external There are too many suspicious points and uncertainties in the body surface markers. The centerline of the X-ray should be as parallel as possible to the tangent to the interproximal surface of the tooth being examined. The word "as far as possible" in it shows its doubts and inaccuracies. There is also too much room for error in the projection process. The other is the parallel projection technology. When the parallel projection technology is used, the center line of the X-ray is perpendicular to the film surface, which is no longer an imaginary line perpendicular to the split angle technology. Therefore, it is easy to be technically guaranteed. However, the parallel projection technology also has theoretical perfection. There are many frustrations in implementation. It is limited by the patient's oral volume and cannot be operated. , the position of the image plate at this time has been cruising out of the mouth. The two sets of technical systems are reasonable in the principle of projection, but there are too many uncertainties in the actual operation of fixed-point positioning.
因此，本领域的技术人员致力于开发一种牙片机X射线束光器，根据照射区域合理化减少射线辐射，更精准投照区域，减少避免非检查区的额外照射，可以减少患者辐射剂量，增强图像质量。Therefore, those skilled in the art are committed to developing a dental X-ray beamer, which can reduce radiation radiation according to the rationalization of the irradiation area, more accurately project the area, reduce and avoid additional irradiation in the non-examination area, and can reduce the radiation dose of patients.
