Impact of tissue heterogeneity on intracranial Cesium‐131 brachytherapy dosimetry: A patient‐specific Monte Carlo Study

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background AAPM TG‐43‐based dose calculations for intracranial cesium‐131 (131Cs) brachytherapy ignore patient‐specific heterogeneities, which can affect dose accuracy. This study investigates the dosimetric impact of these heterogeneity effects using Monte Carlo (MC) simulations and patient‐specific imaging data.

Image quality robustness of HyperSight‐enabled versus conventional iterative cone‐beam CT across patient size and imaging geometry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Recent advances in cone‐beam computed tomography (CBCT) have led to the development of next‐generation CBCT systems with enhanced image quality and quantitative imaging capabilities. These advances are particularly relevant in the context adaptive radiation therapy, where improved soft tissue visualization and Hounsfield unit (HU ...

Impact of robust optimization and beam configuration on the distribution stability of LET under delivery uncertainties in carbon‐ion therapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Carbon‐ion radiotherapy exploits high linear energy transfer (LET) to enhance biological effectiveness, and low dose‐averaged LET (LETd) within the target volume is associated with local recurrence in pancreatic cancer. Although robust optimization is widely used to improve dose robustness against delivery uncertainties, systematic ...

Development of a low‐cost 3D‐printed phantom for end‐to‐end testing of model‐based dose calculation algorithms (MBDCAs) in high‐dose‐rate (HDR) brachytherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Model‐Based Dose Calculation Algorithms (MBDCAs), such as AcurosBV, have improved dosimetric accuracy in high‐dose‐rate (HDR) brachytherapy by accounting for medium heterogeneities and variations in scatter conditions. However, their safe and effective clinical implementation requires thorough commissioning, of which end‐to‐end (E2E)

Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

The Anatomical Record, Volume 309, Issue 11, Page 3375-3396, November 2026.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Assessment of bone density on Hounsfield units in the posterior maxilla

, 2016
학위논문 (석사)-- 서울대학교 치의학대학원 : 치의학대학원 치의학과, 2016. 2. 임영준.1. 목 적 치과 임플란트를 이용한 보철치료가 일반화 되면서, 좋은 예후를 위해 식립 전 골질에 대한 평가를 실시하여 예측 가능한 상태로 시술하고 있다. 임플란트의 초기고정성 및 유지는 골질에 영향을 받기 때문에 이를 예측하는 것은 중요하다.

Female Patients Exhibit a Narrower Glenoid Rim and Lower Bone Density in the Anteroinferior Quadrant Compared With Male Patients

Arthroscopy, Volume 42, Issue 11, Page 2473-2481, November 2026.
Purpose The purpose of this study was to evaluate sex‐based differences in glenoid rim morphology and bone density relevant to arthroscopic Bankart repair. Methods This retrospective study assessed differences in glenoid rim morphology between sexes in patients with shoulder instability and uninjured control subjects who underwent a magnetic resonance ...

Surgical Management of a Giant Oropharyngeal Angiolipoma Presenting With Severe Dysphagia: A Case Report

Clinical Case Reports, Volume 14, Issue 11, November 2026.
ABSTRACT Lipomas of the oropharynx are rare, accounting for less than 5% of benign oropharyngeal neoplasms. Most remain asymptomatic until they grow large enough to cause obstructive symptoms. Oropharyngeal angiolipomas are extremely rare and can present with life‐altering symptoms such as dysphagia.
