AUXILIARY DEVICE RADIOGRAPHY AND X-RAY BISECTION PLANE PHOTOGRAPHING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a radiographic auxiliary device capable of easily and accurately deciding the position direction of an X-ray beam applicator at the time of performing virtual bisection plane photographing and an X-ray bisection photographing method using the auxiliary device at the time of stipulating the photographing plane of an affected tooth and X-radiographing the tooth of the bisection plane animal of X-rays by a bisection plane method. SOLUTION: This device is composed of a tooth axis operation guide 53 for stipulating a plane parallel to the X-ray virtual photographing plane of the affected tooth, an X-ray projection reference guide 55 capable of attaching an X-ray imaging means 54 for stipulating an X-ray projection plane, a bisection plane angle instruction means 57 provided with an instruction part for stipulation the irradiation direction of the X-rays and an opening degree position control mechanism for connecting them turnably by an almost common rotary shaft. The opening degree position control mechanism turns in linkage the bisection plane angle instruction means 57 onto the bisection plane of an opening angle formed by the tooth axis operation guide 53 and the X-ray projection reference guide 55.
