摘要： In accordance with an implementation of the present technique, a detector is disclosed. The detector includes a photodetector array and a substrate layer. The photodetector array includes a plurality of photodiodes and a structure of trenches or diffusions grids that electrically isolate each photodiode of the plurality of photodiodes. The plurality of photodiodes and the structure of trenches or deep diffusions grids are disposed on a first surface of the photodetector array and a second surface opposite the first surface is bonded to a substrate layer. The substrate layer is typically made of the same semiconductor material as the photodetector array but heavily doped and conductive to provide cathode contact to the photodetector array in addition to mechanical support.

摘要： A CT detector includes a pixel having a single photodiode and multiple charge storage devices that are alternately stored and read out. The photodiode is a frontlit diode with a pair of capacitors that alternately store charge generated during data acquisition. Multiple pixels are connected to a single readout amplifier. Charge is continuously acquired from each photodiode and stored on the charge storage devices, but such readout is from a single charge storage device at a time. As such, each charge storage device is read out independently, but the charge storage devices are connected to a common readout channel or port.

摘要： An optical mask layer for a CT detector is disclosed and is disposed between the photodiode array and scintillator array of a CT detector. The optical mask layer, which may extend along the x-axis, z-axis, or both, is designed to absorb and/or reflect light emitted the scintillators of the scintillator array. Through this absorption and/or reflection, transference of light photons from a scintillator to the photodiode corresponding to a neighboring scintillator is reduced. This reduction in cross-talk reduces artifacts in a reconstructed image and therefore improves the diagnostic value of the image.

摘要： A method for monitoring the quality of a manufacturing process for making detector panels that have a plurality of pixels in a two-dimensional array includes, in each detector panel, manufacturing a set of baseline pixels and a set of test pixels. Each test pixel has an electrical component having a geometric dimension varied by an amount sufficient to introduce a measurable variation in a test that measures parameters of pixels that are dependent upon the varied dimension. The method further includes performing the test on the set of baseline pixels and the set of varied pixels, analyzing the results of the test, and adjusting parameters of the manufacturing process in accordance with the analysis.

摘要： A solid-state imager with back-side irradiation. The present invention provides a solid-state imager that includes a substantially radiation transparent substrate adapted to receive incident radiation. The radiation travels through the substrate and a pixelated array of photosensitive elements to a scintillator material, which absorbs the radiation. The pixelated array of photosensitive elements receives light photons and measures the amount of light generated by radiation interactions with the scintillator material. With this imager, there is less spreading and blurring and thus a better quality image. In another embodiment, there is a substantially transparent material disposed between the pixelated array of photosensitive elements and the scintillator material. The substantially transparent material absorbs and substantially blocks electrons from entering the active regions of the pixelated array of photosensitive elements. This enables the imager to perform for a longer period of time according to its specifications.
