|PET camera in 3D Mode|
This three dimensional mode is the most common mode of operation of a PET camera. Sensitive scintillator crystals detectors and the coincidence technique remove the need of lead collimators (septa) that were formerly required to select the photons originating from the organ examined. The fact that the direction of the photons is no more imposed by septa increases the sensitivity of the diagnostic and reduce its duration.
