PHANTOM FOR EVALUATING RADIOACTIVE CONCENTRATION RESOLUTION OF CAMERA FOR SPECT AND CAMERA FOR PET, METHOD OF PREPARING IMAGE FOR EVALUATION OF RADIOACTIVE CONCENTRATION RESOLUTION, AND METHOD OF EVALUATING RADIOACTIVE CONCENTRATION RESOLUTION

摘要

PROBLEM TO BE SOLVED: To provide a phantom for evaluating a radioactive concentration resolution for a gamma camera or the like, capable of setting a plurality of radioactive concentrations by only once concentration regulation, without requiring a plurality of times of concentration regulation for a radioactive solution filled into the phantom, and capable of setting repeatingly the radioactive solution of the same radioactive concentration ratio when evaluating the plurality of gamma cameras or the like.;SOLUTION: In this phantom with a cross section photographed by the gamma camera or the like, radioactive solution filling units 40 filled with the radioactive solution are arranged respectively in a storage part 5 and a storage part 6 of an outer container 10, and the two radioactive solution filling units are constituted to allow regulation of a radioactive solution amount per unit area in the cross section of which a cross-sectional image is photographed by the gamma camera or the like.;COPYRIGHT: (C)2007,JPO&INPIT
