WebFeb 8, 2007 · Here, we present the crystal structure of the C-terminal region (residues 575-1,285) of PMT, which carries an intracellularly active moiety. The overall structure of C-terminal region of PMT displays a Trojan horse-like shape, composed of three domains with a "feet"-,"body"-, and "head"-type arrangement, which were designated C1, C2, and C3 ... WebFeb 14, 2024 · The photomultiplier tube array of a Gamma camera detects the visible light produced by the scintillator, and converts it to a measurable electronic signal 1. A series of photomultiplier tubes are mounted behind the scintillation crystal 1. Each photomultiplier tube is composed of a tightly sealed, evacuated glass housing 1.

WebIf the scintillation crystal is attached directly to the photomultiplier tube, the light from radiation interacting close to the interface would interact only with a small region of the … Web7.1 Scintillators and Photomultiplier Tubes When ionizing radiation enters a scintillator, it produces a fluorescent flash with a short decay time. This is known as scintillation. In the case of gamma rays, this scintillation occurs as a result of excitation of the bound electrons by means of free electrons inside the scintillator.
