HIV incidence among men with and those without sexually transmitted rectal infections: estimates from matching against an HIV case registry.

Clinical Infectious Diseases, 2013
BACKGROUND Sexually transmitted bacterial rectal infections are objective markers of HIV risk behavior. Quantifying HIV risk among men who have sex with men (MSM) who have had these infections can inform prevention efforts. We measured HIV risk among MSM

Practical experience in commissioning ring applicators using ring applicator component type with bravos control software v1.2

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose The Bravos v1.2 control software introduces a ring applicator component type (ACT) with channel length verification to address geometric characteristics and dosimetric discrepancies caused by source positioning inaccuracies. This study aims to commission the ring applicator and investigate the new ring ACT in Bravos 1.2.

Position‐dependent offset corrections for ring applicator reconstruction in cervical cancer brachytherapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Due to the tight curvature in their design, ring applicators are usually associated with large positioning errors. The standard practice to correct for these deviations based on global offsets may not be sufficient to comply with the recommended tolerance.

Open‐source deep‐learning models for segmentation of normal structures for prostatic and gynecological high‐dose‐rate brachytherapy: Comparison of architectures

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background The use of deep learning‐based auto‐contouring algorithms in various treatment planning services is increasingly common. There is a notable deficit of commercially or publicly available models trained on large or diverse datasets containing high‐dose‐rate (HDR) brachytherapy treatment scans, leading to poor performance on images ...
