Latest Patents
One of Xiaochun Lai's latest patents is titled "Bad detector calibration methods and workflow for a small pixelated photon counting CT system." This invention provides a method and apparatus for diagnosing and calibrating underperforming pixels in detectors. It utilizes a series of tests on image data acquired in-situ during calibration scans. The tests help identify underperforming pixels, allowing for the replacement of their data with information from surrounding pixels through interpolation. The underperforming pixels are cataloged in 'bad' pixel tables, which can be specific to different image types and protocols.
Another significant patent is "Scatter and random coincidence rejection." This invention leverages multiple interactions, such as Compton scattering, within a PET detector to predict the direction of incident photons. By identifying true coincidence events versus scatter or random coincidence events, this technique enhances the image reconstruction process. The methods disclosed can be implemented in a LYSO/SiPM-based layer stacked detector, which accurately registers the 3D position of multiple interactions.
