DOI: 10.1002/mp.12074
Abstract: Purpose: Online tumor matching for SABR lung setup requires margins for inaccuracies due to intra‐fraction variability of breathing‐averaged tumor position (BATP) and CBCT image guidance. We studied intra‐fraction variability during SABR delivery using VMAT, corrected… read more here.

DOI: 10.1088/1361-6560/ab33db
Abstract: We have previously developed a robotic ultrasound imaging system for motion monitoring in abdominal radiation therapy. Owing to the slow speed of ultrasound image processing, our previous system could only track abdominal motions under breath-hold.… read more here.

DOI: 10.3389/fonc.2021.690422
Abstract: Background Understanding intra-fractional prostate motions is crucial for stereotactic body radiation therapy (SBRT). No studies have focused on the intra-fractional prostate motions during re-irradiation with SBRT. The objective was to evaluate these translational and rotational… read more here.
