摘要： A method for obtaining data includes scanning an object with radiation to collect projection data using an imaging system having a detector array with detector cells and a post-patient collimator, wherein the post-patient collimator has plates having non-uniform thicknesses. The method further includes applying a correction to the projection data to shift an effective center of at least some of the detector cells to compensate for the non-uniform thicknesses of the collimator plates.

摘要： The present disclosure relates to radiation detectors having a layer of a high Z material, such as tungsten or lead, disposed on a face of a photodetector layer or other underlying layer. In one embodiment, the layer of the high Z material substantially prevents radiation from reaching on or more electronics components or circuits, such as an analog-to-digital conversion ASIC or other circuit.

摘要： A photodiode assembly includes a semiconductor substrate, a photodiode cell, a ground diffusion region, and a guard band. The photodiode cell includes a first volume of the substrate doped with a first type of dopant. The diffusion region includes a second volume of the substrate that is doped with a second, opposite type of dopant. The guard band is disposed in the substrate and at least partially extends around an outer periphery of the photodiode cell. The guard band includes a third volume of the substrate that is doped with the first type of dopant. At least one of the ground diffusion region or the guard band is conductively coupled with a ground reference to conduct one or more of electrons or holes that drift from the photodiode cell through the substrate. The guard band is disposed closer to the photodiode cell than the ground diffusion region.
