Routine imaging QA is critical for ensuring precise HDR prostate brachytherapy delivery. This study sought to verify the accuracy of the ultrasound imaging system and to identify potential improvements in quality-control processes and real-time treatment moni...
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...
To quantify the relationship between estimated glomerular filtration rate (eGFR) and intra-fractional bladder filling during online adaptive radiotherapy (oART) and to evaluate the dosimetric effect on surrounding organs at risk (OARs).
