Abstract

When urinary organ contrasting inspection is performed using a fluoroscopy for digestive organs, an region of interest such as a bladder often comes to the vicinity of the foot side end of a top plate, and since an X-ray tube device and an X-ray image detecting section are interlocked such that the focal point of the X-ray tube device comes directly above the central position of the X-ray image detecting section, the focal point often fails to be located directly above the region of interest in the vicinity of the foot side end of the top plate. Consequently, it is often the case that the irradiation field cannot be limited to a suitable area to the region of interest and only oblique photography can be performed. When urinary organ contrasting inspection is performed, an X-ray tube device (1), an X-ray diaphragm (16) and an X-ray image detecting section (3) are interlocked such that the foot side end of irradiation field matches the foot side end of the X-ray image detecting section (3). Consequently, the focal point (1A) of the X-ray tube device (1) can be moved directly above the foot side end of the X-ray image detecting section (3).

Description

technical field [0001] The invention relates to an X-ray perspective photography device. Background technique [0002] X-ray fluoroscopy devices for the digestive tract, such as figure 2 Shown is composed of a top plate (top plate) 4, an X-ray tube device (X-ray tube device) 1, an X-ray diaphragm (X-ray diaphragm) 16, and an X-ray image detecting section (X-ray image detecting section) 3, etc. constitute. The top plate 4 is held by a main pillar 5 vertically erected on the floor via a base 6, and a subject (not shown) is placed thereon. The X-ray tube device 1 is held by an arm 26 attached to a support 2 , and the support 2 is held movably in the longitudinal direction of the top plate 4 by a main support 5 . The X-ray diaphragm 16 is attached to the X-ray irradiation part of the X-ray tube device 1 to open and close a rectangular irradiation field. The X-ray image detection unit 3 is disposed on the back of the top plate 4 facing the X-ray tube device 1, is held movably...
