Title:
IMAGE RECONSTRUCTION PROCESSOR
Document Type and Number:
Japanese Patent JP3947201
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an image reconstruction processor used in an apparatus using a cone beam-like X-ray to perform both fan beam reconstruction and cone beam reconstruction, and improved in operability.
SOLUTION: In this image reconstruction processor, a conical X-ray is radiated from an X-ray source 3 and transmitted through an object, and the transmitted X-ray is detected by an X-ray detector 5, and an image is reconstructed according to the detection data. The processor includes: a reconstruction unit 12-2 for generating an image in fan beam reconstruction according to the transmitted X-ray detection of the X-ray detector; a reconstruction unit 12-1 for generating an image in cone beam reconstruction according to the transmitted X-ray detection of the X-ray detector; a reconstruction control part 21-1 for switching between the fan beam reconstruction unit and the cone beam reconstruction unit; and a data control part 21-3 for controlling the detection data or the reconstruction data to be saved or not saved depending on switching between the fan beam reconstruction unit and the cone beam reconstruction unit performed by a control part.
