For radiopharmaceuticals emitting high linear energy transfer (LET) particles, such as alpha particles, the spleen can receive substantial localized doses due to its reticuloendothelial function. To capture dose heterogeneity, th...

Extremely sparse-view CT benefits for reducing radiation dose while causing streak artifact when using the traditional filtered-back projection (FBP). We propose a new learning-based reconstruction method, named HYPER (HYbrid fra...

To assess the agreement in motion tracking at a mobile cone-beam computed tomography (CBCT) X-ray imaging system integrating optical cameras, at varying gantry angle and controlled breathing periods.

To evaluate the feasibility of a hydrated-electron dosimeter prototype for proton FLASH beams and to characterize its sensitivity and response.

This work evaluates Varian’s HyperSight CBCT system installed on the Ethos radiotherapy platform using head-and-neck (H&N) patient cases to characterize the image quality and dose-calculation accuracy in the presence of metal-ind...

To evaluate the feasibility of HyperSight CBCT–based radiotherapy planning on the Varian Ethos v2.0 platform and to develop a clinically deployable simulation workflow that overcomes current system limitations.

Kilovoltage cone-beam CT (kV-CBCT) is routinely used for image-guided radiotherapy (IGRT). However, image artifacts and limited Hounsfield unit (HU) stability strict its application in adaptive radiotherapy. Recently, HyperSight...

Radiomics-enabled adaptive radiotherapy depends on on-treatment imaging that maintains CT-like quantitative biomarkers. We evaluated whether HyperSight CBCT preserves planning-CT radiomic biomarkers more faithfully than conventio...

Online adaptive lung radiotherapy has not been widely reported due to challenges in respiratory motion. This study evaluates the clinical performance of HyperSight slow-scan CBCT for target delineation, dose calculation accuracy,...

Quantitative image-based dosimetry for radiopharmaceutical therapy (RPT) increasingly relies on large, multi-organ mechanistic models of physiologically based pharmacokinetics (PBPK). While PBPK models often fit clinical data wel...

Plastic Scintillation Detectors (PSD) have shown great potential for dose measurements, but extraction of dwell-time in particular sub-seconds is plagued with small signal. This study aims to evaluate inorganic scintillator (ISD)...

To evaluate the use of image-guided radiation therapy (IGRT) tools and physics plan review practice in low- and middle-income countries (LMICs). By identifying barriers to IGRT implementation, this study aims to inform best pract...

To quantitatively evaluate and compare imaging performance of various kV-CBCT systems implemented on modern C-arm and O-ring linear accelerator units.

To investigate the impact of post-processed true axial reconstructions of axial head CT scans.

Deep learning-based image reconstruction and noise reduction (DLR) techniques are increasingly adopted in clinical CT to improve image quality at reduced radiation doses. While prior studies have demonstrated benefits for lesion...

To synthesize gold nanoparticles Au197 and Au198 and to evaluate their interaction with MCF-7 breast cancer cells using imaging techniques based on Raman spectroscopy and CLSM Confocal Microscopy.

To optimize a simulation imaging protocol for MR-only treatment planning (MRTP) of high-dose rate (HDR) brachytherapy (BT) in patients diagnosed with prostate cancer.

Accurate delivery of MR-guided adaptive radiotherapy (MRgART) for prostate SBRT is influenced by inter- and intra-fraction motion, planning target volume (PTV) margin selection, and verification adaptation. Our study quantified m...

To assess how different treatment planning techniques affect dose homogeneity and OAR sparing in VMAT total-body irradiation (TBI) plans.

Accurate delineation of anatomy on cone-beam CT (CBCT) is essential for image-guided and adaptive radiotherapy in head and neck cancer, yet image quality and deformable image registration (DIR) performance remain limiting. This s...

Radiomic survival models often have substantial class imbalance, which can distort patient ranking and reduce the reliability of predicted survival probabilities. This study evaluated commonly used imbalance-handling strategies a...

RapidArc Dynamic (RAD) in Eclipse, version 18.1 integrates dynamic collimator rotation with static angle modulated ports (STAMPs) into arc to improve plan quality and treatment time. Flattening filter–free (FFF) beams further red...

Radiation pneumonitis (RP) remains a major toxicity in thoracic radiotherapy. While lung radiomics has shown promise for RP prediction, the optimal region for feature extraction remains unclear. This study investigated whether re...

Dynamic Swing Arc (DSA) irradiation with the OXRAY radiotherapy system integrates simultaneous gantry rotation and ring motion, enabling high-dose-rate delivery for prostate stereotactic body radiotherapy (SBRT). Although the sys...
