X-ray imaging apparatus, method of controlling the same, and computer program

摘要

An X-ray imaging apparatus includes an X-ray source including a plurality of X-ray focuses, an X-ray detector which detects X-rays emitted from the X-ray focuses and transmitted through an object, and a control unit which controls the X-ray source and the X-ray detector. The X-ray imaging apparatus selects a pair of X-ray focuses, of X-ray focuses of the plurality of X-ray focuses which project images on the X-ray detector through a region of interest which is an imaging region of the object, from which emitted X-rays define an intersecting angle coinciding with a predetermined angle in the region of interest, and decides an X-ray focus to be used for imaging from X-ray focuses between the selected pair of X-ray focuses. An X-ray image is captured by emitting X-rays from the decided X-ray focus and causing the X-ray detector to detect the X-rays.

主权项

1. An X-ray imaging apparatus for capturing an X-ray tomogram of an object, comprising:
a selection unit configured to select two X-ray focuses out of a plurality of X-ray focuses which project images on an X-ray detector through a region of interest which is an imaging region of the object, the selected two X-ray focuses having an intersecting angle of a predetermined value in the region of interest; and a control unit configured to control the X-ray focuses existing between the selected two X-ray focuses to emit X-rays and to control the X-ray detector to detect the emitted X-rays, for capturing an X-ray image, wherein, after the two X-ray focuses are selected by the selection unit, the selection unit selects other two X-ray focuses by decreasing the intersecting angle in the region of interest.
