Title:
Ｘ線撮影装置及びその制御方法
Document Type and Number:
Japanese Patent JP5723432
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce or eliminate data missing areas that appear between pitches of X-ray sources and to reduce the effect of scattered radiation in X-ray photographing using plural X-ray sources.SOLUTION: An X-ray photographing apparatus comprises: a multi-X-ray generating part which has a predetermined pitch in a first direction and also has plural X-ray foci two-dimensionally arranged; and a slit part which has plural slit members opposed respectively to each of the plural X-ray foci. In this configuration, each of the plural slit members has plural slits arranged in the first direction, and each of the plural slits forms a slice-like X-ray beam with a second direction, different from the first direction, as its lengthwise direction. A two-dimensional detection part detects the X-ray intensity of the formed X-ray beam on a detection surface. With the multi-X-ray generating part and the slit part being held in a relative positional relation, the X-ray photographing apparatus carries out X-ray photographing at plural positions while moving toward the first direction a predetermined pitch, and reconfigures the X-ray images on the basis of the obtained X-ray intensities.
