A multi-institutional journal club (MIJC) was introduced by the AAPM’s Working Group on Multi-Institutional Journal Clubs for Residency Programs (WGJCRP) in 2021. As of 2022, 40% of therapy programs were participating. The MIJC program was intended to connect...

Surface-guided radiotherapy (SGRT) has changed how we position and watch patients—by giving the team a live, camera-based view of the body’s surface without extra markers or tattoos. This exploratory session looks at what’s next: using that same surface infor...

Therapy Physics

Brachytherapy, as a specialized subfield within radiation oncology, demands rigorous education, hands-on training, and substantial clinical experience. Its technical complexities and the risks associated with treatment delivery underscore the need for standar...

High-dose-rate (HDR) vaginal brachytherapy often employs shielded applicators to enhance organ-at-risk (OAR) sparing—particularly rectal protection—in cases with asymmetric tumor distribution. Although the shield thickness in cylindrical applicators was origi...

To evaluate the dosimetric impact of rotational alignment errors on volumetric modulated arc therapy (VMAT) craniospinal irradiation (CSI), with emphasis on ring-based gantry platforms that lack rotational couch corrections. Given increasing interest in anter...

Spatially fractionated radiation therapy (SFRT) requires accurate placement of high-dose vertices to preserve peak-to-valley dose ratios (PVDR) and limit dose to surrounding organs at risk (OARs). This study evaluates the impact of breath-hold–based motion ma...

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...

Present interim dosimetry analysis from a prospective, multi-center study (NCT05953337) comparing the mean absorbed dose (Dmean) derived from nuclear medicine (NM) and CT imaging of liver cancer patients undergoing yttrium-90-radioembolization (90Y-RE) with r...

In radiation oncology, advanced imaging tools such as dual-energy computed tomography (DECT) offer the potential for improved tumor delineation and reduced proton range uncertainty. Such technologies are often introduced into clinical workflows without compre...

Phase II and III clinical trials establish standards of care in radiation oncology; however, achieving equivalent clinical outcomes in routine practice depends on the reproducible implementation of trial protocols. We systematically evaluated whether publishe...

Osteoarthritis (OA) affects nearly one in four adults worldwide and has become an escalating public health concern. Medical and surgical interventions often carry notable morbidity, cost, and side effects. As a noninvasive alternative, low-dose radiotherapy (...

This session is jointly organized by the Working Group on Radiation Dosimetry and Task Group 359 on FLASH (ultra-high dose rate) radiation dosimetry. The session will begin with an educational review of currently available radiation dosimeters used for both c...

Dose evaluations for brachytherapy have traditionally followed the TG-43 formalism, with its simplifying assumptions of a water-equivalent patient. However, patient-specific model-based dose calculation algorithms (MBDCAs) can offer more accurate doses for tr...

Focused on the "fringes" of Medical Physics - in line with AAPM strategic plan - expanding beyond the current boundaries of Medical Physics. Collecting non-traditional science that belongs/should belong to medical physics. Fun, stimulating, and thought-provok...

Proton arcs, upright protons, and economics

This session will bring together researchers, clinicians, and industry partners engaged in preclinical radiation and imaging studies to discuss strategies for reducing animal use while maintaining scientific rigor. With recent federal guidelines emphasizing t...
