Diagnosis assisting apparatus, diagnosis assisting program, and diagnosis assisting method

摘要

Providing a diagnosis assisting apparatus that allows, in a diagnostic screen of a tubular tissue, easy understanding of the positional relationship between a curved cutting surface represented by a CPR image and the tubular tissue. Extracting a tubular tissue region representing a tubular tissue from volume data obtained by imaging and setting a core line to the tubular tissue, generating a CPR image which includes the core line and a longitudinal section of the tubular tissue region, obtaining the longitudinal section from the CPR image generation means, generating a pseudo three-dimensional image that includes a mark representing the obtained longitudinal section, as well as the tubular tissue in the extracted tubular tissue region based on the volume data, and displaying the pseudo three-dimensional image.

1. A diagnosis assisting apparatus, comprising:
a tubular tissue extraction means for extracting a tubular tissue region representing a tubular tissue from volume data obtained by imaging and setting a core line to the tubular tissue; a CPR image generation means for generating a CPR image which includes the core line and a longitudinal section of the tubular tissue region; a longitudinal section obtaining means for obtaining the longitudinal section from the CPR image generation means; a pseudo three-dimensional image generation means for generating a pseudo three-dimensional image that includes a mark representing the obtained longitudinal section, as well as the tubular tissue, in the extracted tubular tissue region based on the volume data; and a display control means for causing the pseudo three-dimensional image having the mark to be displayed on a display device, wherein the mark is shaded based on an angle of a normal line at each position of the longitudinal section.
