Adaptive radiotherapy (ART) is designed to improve target coverage and normal tissue sparing compared with non-ART treatment. While in prostate SBRT differences between adaptive and non-adaptive plans are often modest, certain fractions exhibit clinically sig...

Single-isocenter SBRT enables efficient treatment of multiple liver metastases but limits mitigation of rotational error. This study evaluates rotational uncertainty effects on target coverage in single-isocenter liver SBRT for patients with 5+ metastases.
Surface-guided radiation therapy (SGRT) uses external surface motion as a surrogate for internal target position. While strict SGRT tolerances (typically ±1mm) are common, they may still be permissive for patients with small surface excursions. In these cases...
End-expiration breath hold (EEBH) is commonly employed in GI radiotherapy to enable dose escalation while minimizing dose spillage to adjacent organs at risk. Surface-tracking systems are frequently used to support patient breath-hold stability. This study co...
Adaptive radiotherapy (ART) enables daily plan adjustment to account for anatomical changes. Given the high doses and tight margins in prostate SBRT, this study quantifies intrafractional prostate motion and its implications in the PTV margins.
