Abstract
C-arm cone-beam CT is an emerging tool for intraoperative imaging, but currently exhibits modest soft-tissue imaging capability. This work adapts a spectrum of statistical iterative reconstruction approaches to C-arm CBCT and investigates performance in imaging of low-contrast tasks pertinent to soft-tissue surgical guidance. Experiments involved a mobile C-arm and phantoms and cadavers presenting soft-tissue structures imaged using 3D FBP and penalized likelihood reconstruction. Statistical reconstruction - especially non-quadratic PL - boosted soft-tissue image quality through reduction of noise and artifacts, therefore presenting promise for interventional imaging. Further investigation of task-specific performance may overcome conventional tradeoffs in noise, resolution, and dose.
