Document Type and Number:
Japanese Patent JP6732489
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technology to support X-ray imaging apparatus alignment adjustment capable of reducing a degree of dependence on a skill of an operator.SOLUTION: An alignment adjustment support device 30 includes a transparent image input part 31 for radiating an X-ray output from an X-ray source 11 to six reference points 20 positioned in the coordinate system (X, Y, Z) in a treatment space, and inputting a transparent image 13 projected on an X-ray detector 12, a determination part 32 for determining projective coordinates (u,v) of the six reference points recognized in the coordinate system (u,v) of the transparent image, a derivation part 33 for deriving a projection matrix P for converting spatial coordinates (X,Y,Z) of the six reference points in a spatial coordinate system (X,Y,Z) to corresponding six projective coordinates (u,v), and a calculation part 41 for calculating positional information, etc. on the X-ray source 11 and the X-ray detector 12 in the spatial coordinate system (X,Y,Z) based on the projection matrix P.SELECTED DRAWING: Figure 3
