The lesion detectability of scintillation camera was studied for 201Tl imaging using simulating myocardial phantom having a cold lesion with volume of 12 cm3 (1.3×3×3) . The lesion detectability expressed as level of confidence of visual evaluation on phantom images was discussed with the position of cold lesion and the object contrast defined by the maximum signal to background ratio.
