Multi‐fidelity Monte Carlo fusion for BNCT dose calculation using a dual‐branch network

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Boron neutron capture therapy (BNCT) is a binary radiotherapy that selectively kills tumor cells. Its clinical implementation relies on Monte Carlo (MC)‐based treatment planning systems, which are time‐consuming and limit clinical workflow efficiency.

Image‐based evaluation of a commercial AI synthetic CT generator for brain and prostate MR‐only radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Synthetic CTs (sCT) were developed to provide electron density information for MR‐only treatment planning. Some AI‐based sCT generators have received FDA‐clearance and better capture tissue heterogeneity through voxel‐wise mappings to improve image guidance and dose calculation.

Initial experience of clinical implementation of an Online Simulation‐free CBCT‐based Adaptive Radiotherapy (OSCAR) workflow for palliative and urgent treatment indications

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background The current standard radiotherapy treatment planning workflow typically requires several hours to days, during which patients must wait before treatment can be initiated. In certain oncological situations, however, treatment should commence as soon as possible.

Bilateral anophthalmia with septo-optic dysplasia

Oman Journal of Ophthalmology, 2010
Bilateral anophthalmia is a rare entity and association with septo-optic dysplasia is an even rare condition. The condition is characterized by absent eyeballs in the presence of eyelids, conjunctiva or lacrimal apparatus.

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

The Anatomical Record, Volume 309, Issue 8, Page 1937-1969, August 2026.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Development of the Lacrimal Apparatus in the Rabbit (Oryctolagus cuniculus) and Its Potential Role as an Animal Model for Humans

, 2011
Rabbits have been proposed as a model organism for the human lacrimal apparatus (LA), including the nasolacrimal duct (NLD), based principally on comparative studies of adult morphology; however, little is known about its development.

Supplementary Material for: Large Number of Eyelashes in the Lacrimal Sac Found by Dacryoendoscopy: A Case Report

, 2023
Foreign objects sometimes enter the lacrimal sac. Here, we report the case of a patient with many comb-shaped eyelashes in the lacrimal sac and discuss the potential of using dacryoendoscopy to detect and remove foreign bodies from the lacrimal apparatus.
