Evaluation of fan-beam kilovoltage computed tomography image quality on a novel biological-guided radiotherapy platform

ABSTRACT: Highlights • Described kilovoltage computed tomography (kVCT) on a novel biology-guided radiotherapy linac.• Characterized imaging performance of the on-board kVCT based upon national standard.• Compared image quality of the on-board kVCT to CT simulator on phantom and patients.• kVCT system on biology-guided linac can potentially improve soft tissue image guidance accuracy.

Background and Purpose

A recently developed biology-guided radiotherapy platform, equipped with positron emission tomography (PET) and computed tomography (CT), provides both anatomical and functional image guidance for radiotherapy. This study aimed to characterize performance of the kilovoltage CT (kVCT) system on this platform using standard quality metrics measured on phantom and patient images, using CT s
