Deep Neural Networks for HDR imaging

CoRR, 2016
We propose novel methods of solving two tasks using Convolutional Neural Networks, firstly the task of generating HDR map of a static scene using differently exposed LDR images of the scene captured using conventional cameras and secondly the task of finding an optimal tone mapping operator that would give a better score on the TMQI metric compared to ...

Dose modeling of superficial brachytherapy applicator geometries using multiple radioisotopes

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Superficial brachytherapy enables localized dose delivery for superficial cutaneous lesions, but conventional applicators may be limited in treating extended, irregular, or curved surfaces. Geometric constraints, gaps or overlaps between adjacent applicators, and placement‐related uncertainties can reduce dose uniformity ...

Technologies for engineering repetitive DNA

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Repetitive DNA, a fundamental architectural element of genomes, is widespread across organisms and comprises about 54% of the human genome. With advances in long‐read sequencing and bioinformatics approaches, highly repetitive sequences can now be characterized in depth.

One Stone Two Birds: Sustainable Perovskite Solar Cells Obtained by Using Water‐Based Recycled PbI2 and Guanidinium Thiocyanate Post‐Treatment

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
A simple water‐based recycling and recrystallization method enables the recovery of high‐purity PbI2 from spent perovskite solar cells. With guanidinium thiocyanate treatment to restore film quality, PSCs fabricated using the recycled PbI2 achieve a PCE of 17.25%, comparable to those made from commercial high‐purity PbI2. This scalable, cost‐effective,

Probabilistic quality assurance of biopsy DVH thresholds in HDR prostate brachytherapy under localization uncertainty

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background MR‐US guided biopsies support biologic correlation in HDR prostate brachytherapy, but steep dose gradients and millimeter‐scale localization uncertainty limit the validity of nominal biopsy doses. Purpose To assess how localization uncertainty affects the robustness of biopsy DVH dose thresholds in HDR prostate brachytherapy and to ...

Application of an updated severity‐based FMEA approach to Radiation Therapy QA: A multi‐institutional exercise

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background External beam radiation therapy (RT) involves many complex steps to safely and reliably treat patients. The radiation oncology community has adopted process maps and failure modes and effects analysis (FMEA) to analyze risk using the TG‑100 methodology, but the traditional TG‑100–endorsed risk priority number (RPN) has recognized ...

Estimation of pulmonary function from time‐resolved dynamic chest radiography using machine learning in patients with respiratory disease

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Pulmonary function tests (PFTs), particularly spirometry, are the reference standard for assessing airflow limitation in respiratory diseases such as chronic obstructive pulmonary disease (COPD) and interstitial pulmonary disease.

Performance evaluation of a new type of commercial silicon detectors for photon beam dosimetry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Modern radiotherapy relies on advanced treatment techniques that utilize a large number of small fields, for which maintaining dosimetric accuracy is often challenging. Most vendors have introduced microdetectors suitable for small field dosimetry. Sun Nuclear has developed two silicon diodes with a sensitive volume of 0.35 mm3 that
