Patent number: 10162942Abstract: A method and apparatus for photon, ion or particle counting described that provides seven orders of magnitude of linear dynamic range (LDR) for a single detector. By explicitly considering the log-normal probability distribution in voltage transients as a function of the number of photons, ions or particles present, the binomial distribution of observed counts for a given threshold, the mean number of photons, ions or particles can be determined well beyond the conventional limit.Type: GrantFiled: September 12, 2017Date of Patent: December 25, 2018Assignee: Purdue Research FoundationInventors: Garth Jason Simpson, Ryan Douglas Muir, David Joseph Kissick

Patent number: 10145968Abstract: The present disclosure provides a system and method for efficiently mining multi-threshold measurements acquired using photon counting pixel-array detectors for spectral imaging and diffraction analyses. Images of X-ray intensity as a function of X-ray energy were recorded on a 6 megapixel X-ray photon counting array detector through linear fitting of the measured counts recorded as a function of counting threshold. An analytical model is disclosed for describing the probability density of detected voltage, utilizing fractional photon counting to account for edge/corner effects from voltage plumes that spread across multiple pixels. Three-parameter fits to the model were independently performed for each pixel in the array for X-ray scattering images acquired for 13.5 keV and 15.0 keV X-ray energies. From the established pixel responses, multi-threshold composite images produced from the sum of 13.5 keV and 15.Type: GrantFiled: May 11, 2015Date of Patent: December 4, 2018Assignee: PURDUE RESEARCH FOUNDATIONInventors: Garth Jason Simpson, Ryan Douglas Muir, Nicholas Roman Pogranichniy

Publication number: 20180045939Abstract: A beam-scanning optical design is described for achieving up to kHz frame-rate optical imaging on multiple simultaneous data acquisition channels. In one embodiment, two fast-scan resonant mirrors direct the optical beam on a circuitous trajectory through the field of view, with the trajectory repeat-time given by the least common multiplier of the mirror periods. Dicing the raw time-domain data into sub-trajectories combined with model-based image reconstruction (MBIR) 3D in-painting algorithms allows for effective frame-rates much higher than the repeat time of the Lissajous trajectory. Because sub-trajectory and full-trajectory imaging are different methods of analyzing the same data, both high-frame rate images with relatively low resolution and low frame rate images with high resolution are simultaneously acquired.Type: ApplicationFiled: October 4, 2017Publication date: February 15, 2018Applicant: PURDUE RESEARCH FOUNDATIONInventors: Garth Jason Simpson, Charles Addison Bouman, Ryan Douglas Muir, Shane Sullivan, Justin Allen Newman, Mark Carlsen, Suhas Sreehari
