To provide practical guidelines for imaging dose optimization and establishment of dose reference levels for CBCT in radiation therapy. Such guidelines are essential to ensure adherence to ALARA principles without compromising patient positioning accuracy. Al...
Organ‑level breast dosimetry is essential for developing robust dose-response models of subsequent breast cancer (SBC) risk in female childhood cancer survivors. Historically, epidemiologic studies relied on surrogate metrics such as prescription dose due to...
Cs-131 tile implant–based intracranial brachytherapy requires coordinated interdisciplinary efforts spanning imaging, source management, implantation, post-implant planning, and radiation safety. The extent of inter-institutional variability in these practice...
Brachytherapy dose calculations are commonly based on the AAPM TG-43 formalism, which assumes a homogeneous water medium. Although widely used for HDR and LDR brachytherapy, this assumption inadequately represents dose distributions in heterogeneous tissues,...
The Russian invasion of Ukraine has significantly disrupted radiation therapy (RT) services, highlighting the urgent need to replace Cobalt-60 machines and modernize infrastructure and training across 43 RT centers. In response, Help Ukraine Group (HUG) and R...
High-dose-rate (HDR) tandem and ring cervical brachytherapy requires significant time and resources from implant, to imaging, planning, and treatment. The high-risk clinical target volume (HR-CTV) and organs at risk (OARs) are contoured on MRI. To save time a...
Preclinical glioblastoma (GBM) models are crucial for the development of novel therapeutic strategies to improve GBM outcomes. Highly conformal conventional fractionation forms the basis for standard-of-care radiotherapy (RT) in human GBM. However, most precl...
The 2018 EMBRACE II study emphasizes minimizing vaginal mucosal dose during locally advanced cervical cancer brachytherapy. While traditional organs at risk include bladder, rectum, and sigmoid, vaginal mucosa dose has gained attention due to late toxicities...
GammaTile cesium-131 collagen tiles provide immediate postoperative radiation therapy for brain tumors by lining the resection cavity, delivering a steep dose fall-off to target residual disease while sparing healthy tissue. However, intraoperative verificati...
To survey current clinical practice, assess priorities, and identify resource gaps related to environmental sustainability in medical imaging physics.

To develop the first quadrature RF volume coil for 10.5T MRI, using metasurface technology to overcome limitations of traditional volume coil designs.
Supporting MR protocol design, optimization, and management is an important role for a diagnostic medical physicist. However, unless a physicist has extensive MR training, these tasks can feel overwhelming due to the breadth and variety of MR protocol types,...
