Physical Performance of the new hybrid PET/CT Discovery-690

Purpose: The aim of this work was the assessment of the physical performance of the new hybrid PET/CT system: Discovery-690. Methods: The Discovery-690 combines a lutetium-yttrium-orthosilicate (LYSO) block detector designed PET tomograph with a 64-slice CT scanner. The system is further characteriz...
