Description
This work presents a new PET detector concept for compact preclinical hybrid simultaneous MR-PET. The detector concept is based on Linearly-Graded SiPM produced with FBK RGB-HD technology. One 7.75mm x 7.75mm large sensor chip is coupled with optical grease to a black coated 8mm x 8mm large and 3 mm thick monolithic LYSO crystal. The readout is obtained from four readout channels with linear encoding based on integrated resistors and the Center of Gravity approach. The measurement setup was prepared to center, edge and corner point that all significant points of the detector were covered. A CRT of 360 to 510 ps for different points of the detector was achieved.
Due to the reduced thickness, the sensitivity of this gamma detector is low but still higher than pixelated designs with the same thickness due to the monolithic crystals. Combining compact design, high spatial resolution, and high sensitivity, the detector concept is particularly suitable for applications where the scanner bore size is limited and high resolution is required - as is the case in small animal hybrid simultaneous MR-PET.
