Title:
MEDICAL IMAGE PROCESSING APPARATUS, PROGRAM MOUNTABLE ON MEDICAL IMAGE PROCESSING APPARATUS, AND MEDICAL IMAGE PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2018043021
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a medical image processing apparatus capable of displaying images which enable a user to easily distinguish an abnormal region containing cancer cells, etc. even when the abnormal region is minute or tissue with a low uptake efficiency for a contrast medium.SOLUTION: A correlation between a CT value and a tube voltage is calculated for a pixel at the same coordinates in plural medical images of the same cross section of a subject, the plural medical images being obtained by imaging the cross section at tube voltages different from one another with an X-ray CT apparatus. Control is then performed such that the CT value at each pixel is determined based on the correlation and a user-specified degree of highlighting, and a highlighted image formed of the CT values is generated and displayed. A highlighted image with the degree of highlighting desired by the user is thus obtained, enabling the user to distinguish the abnormal region easily.SELECTED DRAWING: Figure 2
