Abstract
Disclosed are a detection collimation unit, a detection apparatus and a SPECT imaging system. The detection collimation unit includes: a scintillation crystal array configured to receive a gamma photon emitted by a radioactive source in a detected object; and a number of photoelectric devices configured to receive the gamma photon and converting the gamma photon into a digital signal. The scintillation crystal array includes a number of scintillation crystals. The number of scintillation crystals are arranged substantially in parallel and are spaced from each other. Each scintillation crystal has a side face configured to receive a ray emitted by the radioactive source and an end face. The number of photoelectric devices are coupled to the end faces of the number of scintillation crystals.
