Title:
X-RAY TOMOGRAPHY DEVICE AND X-RAY TOMOGRAPHY METHOD
Document Type and Number:
WIPO Patent Application WO/2018/155632
Kind Code:
A1
Abstract:
Provided is a technique for acquiring a high-resolution X-ray projection image without interfering with rotation of an X-ray generator and an X-ray detector. X-ray beams BX1 are radiated through an imaging region ROI from a plurality of directions to obtain an X-ray projection image, by causing an X-ray generator 42 and an X-ray detector 52 to rotate around the head of a subject M1. When a central axis X-ray beam CBX1 which passes through a central axis of rotation RA1, from among the plurality of X-ray beams BX1, is orthogonal to a layer of interest LOI, the X-ray detector 52 is brought closer to the layer of interest LOI and the X-ray generator 42 is moved further away from the layer of interest LOI than when the central axis X-ray beam CBX1 is not orthogonal to the layer of interest LOI.
