NUCLEAR MEDICINE DIAGNOSTIC EQUIPMENT, MEASURING TOOL FOR CORRECTING ROTATIONAL CENTER OF NUCLEAR MEDICINE IMAGE, AND METHOD FOR CORRECTING THE ROTATIONAL CENTER OF THE NUCLEAR MEDICINE IMAGE

摘要

PROBLEM TO BE SOLVED: To improve the quality of nuclear medicine image of nuclear medicine diagnostic equipment.;SOLUTION: SPECT (single-photon emission computed tomography) equipment 10 that has a detector for detecting the gamma rays, radiated from a subject and a rotation support mechanism that rotates the sensor around the body axis of the subject, and then generates nuclear medicine images of the inner section of the specimen according to data collected by the sensor; further includes a means for detecting, by using the sensor from a plurality of directions, gamma rays radiated from a plurality of point sources, accommodated in a measurement tool, and a correction coefficient computing section for computing the inclination correction information for correcting the inclination of a detection face caused by deflection due to the influence of the weight of the sensor, on the basis of the positional information of the point sources collected by the sensor.;COPYRIGHT: (C)2008,JPO&INPIT
