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-...

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...

Gynecologic (GYN) cancer patients frequently experience significant weight loss and nodal volume changes during conventional pelvic radiotherapy, often necessitating re-simulation and potential treatment adaptation. A TrueBeam linear accelerator equipped with...

Vacuum cradles/bags (VC) combined with head and leg immobilization are commonly used for prostate stereotactic body radiotherapy (SBRT) treatment setup. Removing the VC may offer practical advantages for efficient patient positioning, comfort, and high-qualit...
