Embodiment Construction

[0039] To overcome the aforementioned issues, the general-purpose tiled SiPM detector described here can be utilized to realize the basic construction of a SiPM-based solid-state PET detector so that the rest of the PET system infrastructure can be reused without further modification. The basic building block of the sensor is based on an integrated silicon die containing 2x2 or 4x4 SiPMs for individual energy and timing measurements. The universal tile detector can be used for PET, PET computed tomography (CT) and PET magnetic resonance imaging (MRI) and other combinations as well as single photon emission computed tomography (SPECT) imaging.

[0040] Universal Tile Sensor tiles are described here as building blocks for scalable PET detectors, with fixed external dimensions for sensor tiles to use the same readout platform and electromechanical and thermal interfaces. Several grades of sensor fill factors were employed, such as 6x6, 5x5, and 4x4 sensor die for quadratic scinti...

Abstract

A scalable medical imaging detector arrangement is provided, having interchangeable sensor tiles with fixed outer dimensions for a fixed or universal mechanical, electrical, and cooling interface. Different sensor tile types with different performance grades and production costs are configured with a common interface for coupling to the medical imaging device, while the rest of the imaging systemcan remain unchanged.

Description

technical field [0001] The following relates generally to nuclear imaging systems, and more specifically to positron emission tomography (PET) detectors. Background technique [0002] PET detectors with different requirements for energy, timing and spatial resolution usually require different PET detectors, including different readout boards, control units, racks and cooling systems, so it is almost impossible to meet with a single PET detector platform Different market demands. [0003] High-end medical imaging systems, such as time-of-flight (ToF) PET imagers based on yttrium lutetium orthosilicate (LYSO), require the silicon photomultiplier (SiPM) sensor on the surface of the silicon scintillator to have a maximum fill factor for ToF- Best fit timing resolution for PET. [0004] Low-end medical imaging systems are often based on non-ToF scintillators, such as bismuth germanium oxide (BGO) scintillators, where timing resolution is less critical and the light-sharing conc...
