Gamma camera apparatus

摘要

After the position of a collimator (30) with respect to a gamma camera (16) depending on the position of a detection plane (48) in an examinee (14), gamma rays radiated from the examinee (14) are detected by a scintillation detector (44) via a collimator (30) and a scintillator (42), and a signal from the scintillation detector (44) is processed by a signal processing circuit (46) and then transferred to an image reconstructing unit (18), which reconstructs a three-dimensional image of the radiation source in the examinee (14) and displays the three-dimensional image on a display unit (22).
