X-ray photography apparatus

摘要

An X-ray photography apparatus including: a turning arm that supports an X-ray generator and an X-ray detector which are opposed to each other so that the head of a patient can be interposed therebetween, and a moving mechanism that includes a turning part and a moving part. The turning part turns the turning arm about a turning axis with respect to the head. The moving part moves the turning arm relative to the head in a direction perpendicular to the turning axis. The X-ray photography apparatus also includes: an image processor that generates an X-ray image, a photographic region designation part that designates part of a row of teeth along a dental arch as a pseudo intraoral radiography region, and an X-ray forming mechanism that changes the irradiation direction in which the head is irradiated with an X-ray relative to the axial direction of the body axis of the patient.

主权项

1. An X-ray photography apparatus comprising:
a support that supports an X-ray generator and an X-ray detector while said X-ray generator and said X-ray detector are opposed to each other so that a head of a patient can be interposed therebetween, the X-ray detector outputting an electric signal according to an intensity of an incident X-ray; a moving mechanism that includes a turning part and a moving part, the turning part relatively turning said X-ray generator and said X-ray detector about the head by turning said support relative to the head about a predetermined turning axis, and the moving part moving said support relative to the head in a direction perpendicular to said turning axis; a photographic region designation part that designates part of a row of teeth along a dental arch as a pseudo-intraoral radiography region; an irradiation direction changing part that relatively changes an irradiation direction in which the head is irradiated with an X-ray with respect to an axial direction of a body axis of the patient; and a controller that controls said moving mechanism and said irradiation direction changing part, said controller controlling said moving mechanism while changing said irradiation direction according to a position of said pseudo intraoral radiography region, and the position of said pseudo intraoral radiography region being designated by said photographic region designation part.
