Assessment of CBCT Post-Processing Algorithms for Head and Neck Adaptive Radiotherapy: A Cautionary Note on Dosimetric and Anatomical Accuracy

To evaluate the dosimetric and anatomical accuracy of RayStation-generated corrected cone-beam CT (cCBCT) and virtual CT (vCT) for adaptive radiotherapy (ART) in head and neck (H&N) cancer patients with significant anatomical change.

Dosimetric Comparison of High Dose Rate Interstitial Brachytherapy and Stereotactic Body Radiotherapy As Alternative Treatment Methods for Advanced-Stage Cervical Cancer

High-dose-rate interstitial brachytherapy (HDR-IBT) is an essential component of curative treatment for locally advanced cervical cancer (LACC), but it is invasive and resource-intensive. Alternative boost techniques are needed when brachytherapy is not feasi...

Dosimetric Impact of Interfractional Anatomical Changes In Syed HDR Brachytherapy: Is Adaptive Planning Required for Every Fraction?

To quantify the dosimetric impact of interfractional anatomical changes in Syed-based high-dose-rate (HDR) interstitial brachytherapy for locally advanced cervical cancer by comparing a single-plan (non-adaptive) versus multi-planned adaptive strategy.
