To evaluate the feasibility and adapt-to-shape (ATS) workflow efficiency of a novel UPFRONT "Brachy-like" Stereotactic Body Radiation Therapy (SBRT) technique delivered via MR-LINAC. This upfront boost aims to deliver a steep-gradient high dose to a "Virtual-...

Radiotherapy treatment planning is a resource-intensive process characterized by multiple manual steps that can contribute to treatment delays and inter-observer variability. The Radiation Planning Assistant (RPA) is a web-based platform designed to deliver a...

Preplanning is a standard practice for MRI-Assisted Radiosurgery (MARS) LDR prostate brachytherapy; however, HDR procedures often rely on generic needle patterns rather than individualized preplans. Implementing a patient-specific HDR preplan provides an oppo...

To quantify the dosimetric impact of hidden input parameters in three inverse optimization (IO) algorithms—IPSA, HIPO, and MCO—for GYN HDR brachytherapy across two applicator types.

Prostate and perineum edema are known issues for prostate brachytherapy. It could significantly impact the dosimetry for prostate HDR implants with needle displacement since there is a 2-3 hour interval between implant and treatment. The purpose of this proje...

Radiotherapy plan quality education is limited by case availability, frequent clinical interruptions, and difficulty aligning schedules. These barriers leave residents underprepared to identify and correct suboptimal plans, potentially compromising future out...
