Evaluation of tumor localization in respiration motion-corrected cone-beam CT: Prospective study in lung

Abstract

p Conclusions: Motion-corrected CBCT improves lung tumor localization accuracy and reduces motion artifacts in nearly all cases. Motion correction at end expiration using RCCT acquired at simulation yields similar results to that using a RCCT on the treatment day (2-3 weeks after simulation).
