To characterize how decreasing radiation dose affects noise magnitude, noise texture, and task‑based spatial resolution in deep learning(DL) CT reconstruction algorithms.

Very-high-energy electron (VHEE) radiotherapy is an emerging modality that currently lacks established dosimetric verification protocols, motivating the development of real-time treatment monitoring methods. This work investigate...

Pediatric dose from CT remains a concern, and recent evidence from radiotherapy has increased interest in dose to specific cardiac substructures (e.g., the left anterior descending coronary artery). Pediatric whole-body phantoms...

Tumor oxygenation plays a critical role in treatment response and progression. However, repeating PET with hypoxia-specific radioligands at every treatment fraction is not practical. Tumor-vascular status, by contrast, can be ass...

Time of flight (TOF) x-ray imaging is an emerging technology that combines high temporal resolution photon counting detector and very short x-ray pulses to provide additional information about photon interactions. For example, du...

Penile vessels’ morphology and integrity are highly relevant to diagnosis and management of erectile dysfunction, as well as treatment planning for sexual function-sparing pelvic radiotherapy. Automatic segmentation of penile ves...

To examine the dose conformity during planning and delivery for complex C-shaped targets in an investigational RefleXion X2 platform under static and motion conditions.

The goal of this study is to accurately estimate 3D deformation and generate real-time volumetric images using only one or two X-ray projections, overcoming the limitations of ultra-sparse conditions in conventional deformable im...

Image noise is a fundamental determinant of CT image quality and directly impacts diagnostic performance. Conventional noise metrics are typically global and do not account for spatial or organ-specific variations introduced by m...

Conventional Dual-Energy CT (DECT) multi-material decomposition (MMD) often suffers from systematic bias due to linear mixing assumptions that fail to account for nonlinear attenuation effects like beam hardening and scatter. The...
