Title:
IMAGE PROCESSING METHOD, IMAGE PROCESSING DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/053646
Kind Code:
A1
Abstract:
The present invention relates to an image processing method for calculating a washout rate (WR) (%) of a radiopharmaceutical in a region of interest (ROI) of a subject to whom the radiopharmaceutical has been administered, the method including a step for calculating the washout rate (%) using formula (I). (Formula (I) is as defined in the description.)
