A tandem reinforcement learning framework for localized prostate cancer treatment planning and machine parameter optimization

Medical Physics, Volume 53, Issue 2, February 2026.
Abstract Background Volumetric modulated arc therapy (VMAT) machine parameter optimization (MPO) is a complex, high‐dimensional problem typically solved with inverse planning solutions that are both temporally and computationally expensive. While machine learning techniques have been explored to automate this process, they often supplement rather than ...

Biopsy‐proven residual cervical cancer at the end of combined chemoradiation predicts poor outcome—Retrospective single‐center cohort study

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 2, Page 368-376, February 2026.
Biopsy‐proven residual tumor at the end of chemoradiation identifies patients at high risk for disease progression. Despite achieving a delayed histologic complete response 6 weeks later, these patients show significantly worse progression‐free survival, suggesting the prognostic value of early tissue‐based response assessment during brachytherapy ...

Radiation induced lichen planus - an uncommon side effect [PDF]

, 2019
Cutaneous lichen planus is classically characterized by violaceous, pruritic, planar papules and plaques, most commonly affecting the extremities. Lichen planus following radiation therapy is extremely rare and lichen planus following radiation therapy ...

Knowledge‐based deep residual U‐Net (DRU) for synthetic CT generation using a single MR volume for frameless radiosurgery

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Purpose To develop a knowledge‐based deep model for sCT generation from a single MR volume in LINAC‐based frameless SRS, enabling the MR‐only workflow without extra CT simulation. Methods A total of 139 patients were included in the study, with 120 used for training and 19 for testing.

Dosimetric characterization of a liquid‐filled ion chamber array post upgrade and evaluation of improvements for stereotactic plan verification

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Stereotactic ablative radiotherapy (SABR) is a technique developed for delivery of high doses of radiation to target volumes. Standard delivery methods for SABR include dynamic conformal arc therapy (DCAT) and volumetric modulated arc therapy (VMAT) as they allow for meaningful gains in delivery speed and in some instances sparing ...

RapidArc dynamic versus RapidArc: A multi anatomical‐site dosimetric evaluation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background RapidArc (RA) has advanced VMAT delivery; however, challenges remain in achieving optimal organ‐at‐risk (OAR) sparing in complex cases. RapidArc Dynamic (RAD), a next‐generation Volumetric Modulation Arc Therapy (VMAT) technique, incorporates dynamic collimator rotation, embedded static fields, and a faster optimizer to enhance dose
