The user selects which detector's crystal efficiency map in the target ring is to be displayed in fig. 8 by operating the two third switching controls d.

According to other embodiments of the present disclosure, the user may also determine the target detector by a selection operation on the layout structure of the target ring after designating the target ring. In this case, when the detector in the PET apparatus includes multiple layers of crystals (e.g., double layer crystals), in some embodiments, whenever the user selects any one of the layers of crystals in a certain detector (e.g., crystal layer c), it is determined that the user selects the detector in which crystal layer c is located to exhibit the crystal efficiency profile. In other embodiments, when a user selects any one of the crystals in a particular detector (e.g., crystal layer c), then it is determined that the user need only exhibit the crystal efficiency profile for that crystal layer c.

Then in operation S623, a visualization of the object detector in the object ring is displayed in the second region. After the selection of the target ring and the target detector, a visual representation f of the target detector in the target ring can be displayed in the region 8.
