Title
Low-Z target optimization for spatial resolution improvement in megavoltage imaging.
Authors
Connell, Tanner; Robar, James L
Abstract
Recently, several authors have shown contrast improvements in megavoltage portal imaging and cone-beam computed tomography using low atomic number (Z) targets. This work compliments previous studies by investigating the effects of varying different beam production parameters including target atomic number, target thickness, and incident electron energy on spatial resolution.
