Patent number: 10409047Abstract: 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: GrantFiled: October 4, 2017Date of Patent: September 10, 2019Assignee: PURDUE RESEARCH FOUNDATIONInventors: Garth Jason Simpson, Charles Addison Bouman, Ryan Douglas Muir, Shane Sullivan, Justin Allen Newman, Mark Carlsen, Suhas Sreehari

Publication number: 20180025514Abstract: Systems and methods for MBIR reconstruction utilizing a super-voxel approach are provided. A super-voxel algorithm is an optimization algorithm that, as with ICD, produces rapid and geometrically agnostic convergence to the MBIR reconstruction by processing super-voxels which comprise a plurality of voxels whose corresponding memory entries substantially overlap. The voxels in the super-voxel may also be localized or adjacent to one another in the image. In addition, the super-voxel algorithm straightens the memory in the “sinogram” that contains the measured CT data so that both data and intermediate results of the computation can be efficiently accessed from high-speed memory and cache on a computer, GPU, or other high-performance computing hardware. Therefore, each iteration of the super-voxel algorithm runs much faster by more efficiently using the computing hardware.Type: ApplicationFiled: February 16, 2016Publication date: January 25, 2018Applicants: Purdue Research Foundation, HIGH PERFORMANCE IMAGING, INC.Inventors: Charles Addison Bouman, Samuel Pratt Midkiff, Sherman Jordan Kisner, Xiao Wang
