Optimizing the target detectability of cone beam CT performed in image‐guided radiation therapy for patients of different body sizes

PURPOSE: The target detectability of cone beam computed tomography (CBCT) performed in image‐guided radiation therapy (IGRT) was investigated to achieve sufficient image quality for patient positioning over a course of treatment session while maintaining radiation exposure from CBCT imaging as low a...
