The Use of Adaptive Statistical Iterative Reconstruction in Pediatric Head CT: A Feasibility Study

Gregory Vorona

Iterative reconstruction algorithms for CT, which have been made possible through recent advances in hardware capabilities and algorithm design, allow for significant radiation dose reductions with preservation of image quality. CT image reconstruction has traditionally utilized filtered back-projection, which operates on several limiting fundamental assumptions about … more »

Cranial CT with Adaptive Statistical Iterative Reconstruction: Improved Image Quality with Concomitant Radiation Dose Reduction

Otto Rapalino

CT radiation exposure has progressively increased in the last few years because of the wide availability of CT scanners and the increasingly important role of CT imaging as a noninvasive diagnostic technique. Iterative reconstruction techniques offer the possibility of improving contrast resolution while reducing radiation exposure. … more »
