| Popis: |
In gamma ray imaging, a scintillation crystal is typically used to convert the gamma radiation into visible light. Photosensors are used to transform this light into measurable signals. Several types of photosensors are currently in use depending on the application, most known are Position Sensitive Photomultiplier Tubes (PSPMT) or arrays of Silicon Photomultipliers (SiPMs). There have been investigations towards reducing the number of output signals from those photosensors in order to decrease system costs and complexity without impacting system performance. We propose here two different reduction schemes without degradation of the detector performance, keeping a good spatial, energy and timing resolution, specially well suited for monolithic scintillation crystals based detectors. We have carried out comparative results that will be shown. |
