Evaluation of OPTOS wide‐field fundus image projections for radiotherapy planning of uveal melanoma

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.
Abstract Purpose To investigate the relationship between the stereographic and azimuthal equidistant projection (AEP) of the human retina for radiotherapy planning with OPTOS optomap wide‐field fundus images (Optos, UK). Further, the geometric accuracy of an OPTOS fundus image is quantified.

Evaluation and failure analysis of four commercial deep learning‐based autosegmentation software for abdominal organs at risk

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.
Abstract Purpose Deep learning‐based segmentation of organs‐at‐risk (OAR) is emerging to become mainstream in clinical practice because of the superior performance over atlas and model‐based autocontouring methods. While several commercial deep learning‐based autosegmentation solutions are now available, the implementation of these tools is still at ...

Review of the application of dual‐energy CT combined with radiomics in the diagnosis and analysis of lung cancer

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.
Abstract Lung cancer is one of the most common malignant tumors in the world. Early detection and precise treatment are of great significance to clinical decision‐making and patient prognosis. As an emerging imaging technology, dual‐energy computed tomography (DECT) has increasingly prominent advantages in multi‐parameter and quantitative analysis in ...

Evaluation of daily residual pancreatic tumor motion for deep‐inspiration breath‐hold radiotherapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 5, May 2025.
Abstract Purpose Breath‐hold techniques are widely used in radiation therapy to minimize respiratory‐induced tumor or organ‐at‐risk motion. However, residual motion persists, necessitating a reliable daily evaluation method. Methods At our institution, fiducial markers serve as surrogates for target localization in pancreatic cancer treatment.

Does dose calculation algorithm affect the dosimetric accuracy of synthetic CT for MR‐only radiotherapy planning in brain tumors?

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 5, May 2025.
Abstract Purpose This study compares the dosimetric accuracy of deep‐learning‐based MR synthetic CT (sCT) in brain radiotherapy between the Analytical Anisotropic Algorithm (AAA) and AcurosXB (AXB). Additionally, it proposes a novel metric to predict the dosimetric accuracy of sCT for individual post‐surgical brain cases.
