QUANTITY-DETERMINING METHOD OF MYOCARDIAL BLOOD FLOW, BLOOD FLOW QUANTITY-DETERMINING PROGRAM, AND BLOOD FLOW QUANTITY DETERMINING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method of determining myocardial blood flow quantity using an SPECT image, and to provide a program and a system for executing the method.;SOLUTION: The SPECT image of the chest of a subject is acquired, an input function corresponding to the activity quantity in subject's arterial blood plasma is determined, temporary flow quantity in an interesting part is determined, based on the signal intensity in the interesting part in the acquired SPECT image using the determined input function, and the blood flow quantity is determined, by multiplying the temporary flow quantity by a correction coefficient represented by 1/(1-Hm)(where, Hm is a hematocrit value).;COPYRIGHT: (C)2007,JPO&INPIT
