Embodiment Construction
[0042] In order to facilitate a better understanding of the purpose, technical features and effects of the present invention, the present invention will now be further explained with reference to the accompanying drawings and specific embodiments.
[0043] Before introducing the present invention in detail, the concepts of "collimation layer" and "dislocation coupling" are first defined. The collimation layer can be understood from two perspectives: one is to regard it as a sub-collimator obtained by dividing a collimator 1 (cutting the hole short); the other is to form a collimator by stacking it in series. Each of the plurality of collimators 1 of the collimation system. For a gamma photon to pass through a collimator containing multiple collimation layers, it must pass through each collimation layer in turn. Dislocation coupling means that the centerlines of the two collimation holes 2 do not overlap when the two collimation layers are coupled in series. On the contrary, t...
