Accurate estimation of diagnostic imaging medical physics staffing requirements remains challenging as clinical scope, regulatory burden, and academic expectations expand. Although multiple activity-based staffing models are comm...

Ventricular tachycardia (VT) arises when abnormal electrical impulses create rapid, self-sustaining ventricular activation instead of normal sinus rhythms. Stereotactic arrhythmia radioablation (STAR) is increasingly used as salv...

To demonstrate a multi-modal magnetomechanical imaging platform for fetal cardiac evaluation that integrates simultaneous fetal magnetocardiography (fMCG) and fetal echocardiography (fEcho). This is achieved by developing a metho...

Current motion management systems are reactive: they detect patient displacement but require 200-400 ms to respond. This limitation prevents anticipatory intervention during breath-holds, forcing patients to their physiological l...

In-vivo dosimetry requires compact dosimeters suitable for patient placement, with multiple detectors often deployed simultaneously for spatial sampling. The 2023 nanoDot OSLD recall left many clinics without accessible, low-cost...

Liver biopsy is the gold standard for evaluating liver fibrosis, yet it is invasive and subject to sampling error and interobserver variability. We therefore developed a B-mode ultrasound-based deep learning model for noninvasive...

Automating medical physics scheduling is challenging due to the need to balance clinical coverage, fairness, employee preferences, and quality-of-life considerations. This work presents a multi-criteria optimization (MCO)–based s...

Real-time liver motion tracking is essential in image-guided radiotherapy to enable precise tumor targeting. We developed a conditional latent point cloud diffusion model (Latent-Liver) for real-time deformable liver motion track...

Monitoring real-time pancreatic target motion during radiotherapy is challenging. The diaphragm can be tracked by ultrasound; however, published findings on its correlation with abdominal motion are inconsistent. We aimed to deve...

Alzheimer’s disease (AD) progression can be monitored with longitudinal PET imaging. Changes in amyloid and tau; two characteristic AD proteins, are measured using [11C]PiB and [18F]AV1451, similar to how serial imaging with [18F...

External beam radiotherapy (RT) for ocular tumors is challenged by intra-fractional ocular motion. Although thermoplastic immobilization masks reduce head mobility, eye mobility remains problematic. Current motion-management opti...

Motion estimation naturally requires two time points, making it inherently a relational quantity. This constrains how motion can be learned during training, as the entanglement of paired data makes cross-modality and cross-dimens...

For single-isocenter multi-target (SIMT) stereotactic radiosurgery (SRS), benchmarking, auditing and inter-institutional standardization of dose delivery remains challenging as it requires specialized equipment and expertise. Ele...

Accurate measurement of the arterial input function (AIF) is important for kinetic modelling in dynamic PET but typically requires invasive arterial blood sampling. This study validates a novel quantification framework that lever...
