SparseCT: System Concept and Design of Multi-slit Collimators.

Summary of "SparseCT: System Concept and Design of Multi-slit Collimators."

SparseCT, an undersampling scheme for compressed sensing CT, has been proposed to reduce radiation dose by acquiring undersampled projection data from clinical CT scanners . SparseCT partially blocks the x-ray beam with a multi-slit collimator (MSC) to perform a multidimensional undersampling along the view and detector row dimensions. SparseCT undersamples the projection data within each view and moves the MSC along the z direction during gantry rotation to change the undersampling pattern. It enables reconstruction of images from undersampled data using compressed sensing algorithms. The purpose of this work is to design the spacing and width of the MSC slits and the MSC motion patterns based on beam separation, undersampling efficiency, and image quality. The development and testing of a SparseCT prototype with the designed MSC will be described in a following paper.
