To evaluate the performance of a digital, imager-based automatic exposure control (AEC) system for bedside radiography that uses a low-dose scout image to adaptively select x-ray technique, and to compare its exposure control and...

In vivo dosimetry is essential for treatment verification and patient safety. Although commercial radiochromic film systems are established for photons, proton therapy adds complexity because film response is energy dependent and...

Upright radiotherapy offers physiological and dosimetric advantages. Mevion S250-FIT, world’s first clinical ultra-compact synchrocyclotron-based upright proton therapy system, incorporates a novel upright CT for treatment planni...

The purpose of this study is to evaluate the accuracy of dose calculation using TrueBeam HyperSight CBCT (HS-CBCT) for measured values in lung treatment planning using the End-to-End (E2E) phantom.

To evaluate a multi-antenna microwave imaging system capable of producing high-resolution three-dimensional images of different phantom models representing abdominal, thoracic, and brain tissues.

This work demonstrates the dosimetric performance of the developmental Anchor Point Tracking algorithm using phantom data acquired on the RefleXion X2 system with wide field-of-view PET detectors and software emulation of treatme...

Currently, there is no standard geometry identified to maximize therapeutic benefits of spatially fractionated radiotherapy (SFRT). This work aims to assess bystander effects in vitro after SFRT while identifying which SFRT geome...

To evaluate image quality for the Kilovoltage Optimized AcceLerator Adaptive radiotherapy (KOALA) system, a dual-robot cone-beam CT (CBCT) imaging and radiotherapy device.

To quantitatively and qualitatively assess CBCT image quality and achievable dose optimization following an upgrade from an aSi1200 to HyperSight imaging panel.

To quantify the discrepancies that occur when a proton treatment plan is delivered on daily anatomy, following the clinical standard of marker-based registration using daily CT imaging. This study aims to demonstrate the necessit...

Synthetic CT (sCT) derived from CBCT images show potential to facilitate online adaptive radiotherapy (oART) by enhancing CBCT image quality. Compared to sCT from a 2D deep-learning (DL) model that can result in through-plane str...

To evaluate the effect of beam orientation on dose distribution robustness in carbon-ion radiotherapy for pancreatic cancer, focusing on stopping power ratio (SPR) variations and their impact on delivered dose accuracy.

To evaluate Eclipse version 18.1 (EV181) with the new Enhanced Leaf Model (ELM) and its impact on SRS/SBRT planning compared with Eclipse version 16.1 (EV161).

To quantify the relationship between estimated glomerular filtration rate (eGFR) and intra-fractional bladder filling during online adaptive radiotherapy (oART) and to evaluate the dosimetric effect on surrounding organs at risk...

To evaluate the clinical impact of the Eclipse Version 18(V18) upgrade, specifically the implementation of ELM, on VMAT plan complexity, delivery efficiency, and dosimetric accuracy compared to the previous Version 15(V15).

HyperSight imaging (HS-CBCT) is commercially available for TrueBeam linear accelerators enabling an advanced iterative reconstruction algorithm with metal artifact reduction (iCBCT-MAR). iCBCT-MAR reduces scatter and improves ima...

Geometric distortions in MRI increase with distance from the magnetic isocenter and may impact spatial accuracy in gynecological interstitial brachytherapy (ISBT). This is particularly relevant for ISBT techniques, such as the Sy...

We implemented a hand-crafted radiomics model and evaluated it against a foundational model, Med3D, a popular transfer network model pretrained on a large-scale medical imaging dataset, for prediction of radiation-associated esop...
