To quantify uncertainty in SPECT sensitivity factor used for Lu-177 radiopharmaceutical dosimetry.

To provide a clinical example of the effect on estimated fetal dose from delivering part of a pregnant cranial radiotherapy patient’s treatment using noncoplanar VMAT arcs, even when those beams are oriented towards the superior...

The aim of this work was to evaluate the need to implement more dosimetric audits in high‐dose‐rate brachytherapy (HDR-BT) in Europe and to identify which characteristics such audits should meet according to users.

Daily Quality Assurance (QA) is critical to ascertain regular checks upon radiation therapy treatment machines and maintain quality of treatment plan delivery for patients. A point of interest is to improve the workflow and ease...

Treatment planning for malignant pleural mesothelioma (MPM) is challenging due to target geometry and organ-at-risk sparing requirements. This study uses RapidPlan-predicted dose volume histograms (DVHs) to guide Monaco planning...

The tumor-to-normal ratio of maximum uptake (Tmax/N) on 18F-BPA PET is widely used to guide decision-making regarding boron neutron capture therapy (BNCT). However, intratumoral heterogeneity of boron drug distribution may also i...

To evaluate the dosimetric and non-dosimetric stability of the Varian Eclipse Treatment Planning System (TPS) following a major software upgrade from v15 to v18. This study is to confirm that the system maintains the integrity of...

To validate plan-delivery log file-based 3D dose calculations with ArcCHECK (AC) 3DVH reconstruction for single-isocenter multiple-target (SIMT) brain plans

To validate the treatment planning system (TPS), RayStation 11B, for IMRT treatment deliveries on the 0.5 T Biplanar Linac-MR (Aurora-RT)

MapCheck3 diode array in the MapPHAN phantom (Sun Nuclear Corporation, Melbourne, FL) appears as a reliable tool for IMRT/VMAT QAs. The objective of this work is the validation of the device for SBRT patient specific QAs (PSQA).

SunNuclear SRS mapcheck diode array is a convenient option for 2D dose mapping combining small detector and relatively small 3.5mm detector grid size in axial direction (2.5mm in diagonal direction). We investigate the utility of...

Tumor-to-normal ratio (TNR) derived from pretreatment Tc-99m MAA SPECT/CT is widely used as a surrogate marker of perfusion in yttrium-90 (⁹⁰Y) radioembolization for patients with hepatocellular carcinoma (HCC). Delivered activit...

Radiation therapy (RT) aims to deliver a therapeutic dose of radiation to the tumor while minimizing exposure to surrounding normal tissues. However, several sources of geometric error can occur: Inter-fractional errors, Intra-fr...

To develop and evaluate a workflow based on scripting for the automation and optimization of volumetric modulated arc therapy (VMAT) treatment planning with simultaneous integrated boost (SIB) for cervical cancer, aiming to impro...

The x-ray tube focal spot is a key determinant of imaging system resolution. Digital pinhole radiography yields the source point spread function (PSFsource) in addition to the nominal size. Using a compact digital detector of a t...

Nuclei segmentation in histopathology images is fundamental for cancer diagnosis and quantitative analysis, yet existing supervised and weakly supervised methods require extensive manual annotations. Although vision–language pre-...

Accurate delineation of the esophageal clinical target volume (CTV) is challenging due to extended longitudinal coverage and substantial slice-wise shape variation. Existing deep learning methods typically require extensive manua...

Cherenkov imaging enables non-invasive, real-time visualization of superficial dose during radiation therapy. In TSET using the Stanford standing technique, dose uniformity is highly sensitive to daily patient positioning. This s...

To refine the photochemical dose–response relationship for single-fraction Photofrin-mediated PDT by relating modeled reacted singlet oxygen dose to long-term tumor control and by using multispectral singlet oxygen luminescence d...
