Title:
DATA PROCESSING DEVICE AND DATA PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2018068982
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve three-dimensional position calculation accuracy of a feature part.SOLUTION: A data processing device comprises: a computed projection image generation unit 112 for generating a computed projection image based on a three-dimensional image; a rigid body area attenuation unit 114 for attenuating a bone area in a captured X-ray image to generate a bone area attenuated X-ray image based on the three-dimensional image; a body motion movement amount calculation/correction unit 116 for generating a bone area attenuated computed projection image which is a computed projection image, in which the rigid body area is attenuated, based on the three-dimensional image, and calculating a body motion movement amount in the bone area attenuated X-ray image based on the bone area attenuated X-ray image and the bone area attenuated computed projection image.SELECTED DRAWING: Figure 1
