Combination radiopharmaceutical therapy (RPT) and external beam radiation therapy (EBRT) is an underexplored strategy that may improve outcomes over either modality alone; however, practical implementation requires a clear unders...

Positron Emission Tomography/Computed Tomography (PET/CT) plays a pivotal role in radiation therapy, particularly in tumor delineation, response assessment, and adaptive therapy planning. However, the reliability of PET/CT depend...

Preplanning is a standard practice for MRI-Assisted Radiosurgery (MARS) LDR prostate brachytherapy; however, HDR procedures often rely on generic needle patterns rather than individualized preplans. Implementing a patient-specifi...

Report commissioning and initial clinical experience using automated breath hold (BH) delivery with Elekta Unity’s Comprehensive Motion Management (CMM).

Single-photon counting computed tomography (SPCCT) offers distinct advantages over conventional CT through energy-resolved measurements, enhanced spatial resolution, and improved soft-tissue contrast. While SPCCT demonstrates uti...

To commission Standard Imaging Exradin W1 scintillator detector (W1) on RefleXIon PET-Linac system for small-field dosimetry in both image-guided radiotherapy (IGRT) and biology-guided radiotherapy (BgRT).

A Valencia-type applicator was recently created by Bebig for use with Varian GammaMedPlus and Varian Bravos afterloaders using an Ir-192 source. To our knowledge, we are the first site to use this applicator with a Bravos afterlo...

To quantify the impact of LDR seed line vs point calculation types in Varian BrachyVision for COMS eye plaque geometry.

A proton conformal FLASH radiotherapy system was developed to generate spread-out Bragg peaks at tumor targets utilizing beam-modifying devices, consist of conformal energy modulator(CEM), range shifter(RS) and brass aperture(BA)...

Alopecia from rotational total skin electron therapy (TSET) poses severe psychological challenges for patients with special social needs. Depending on the location of the disease, some patients may be candidates for scalp-sparing...

We report the first clinical implementation integrating a 6D upright treatment chair and a vertical CT system for image-guided proton therapy on a synchrotron-based fixed-beamline. This design aims to improve patient workflow and...

To quantitatively compare radiation dose output and image quality performance between two cardiac fluoroscopy systems operated under matched exposure conditions, and to assess the impact of proprietary image processing on low-con...

To investigate the role of interplay effects between respiratory motion and proton scanning beam interactions on free-breathing proton lattice radiotherapy (PLT) plans relative to dose distributions from static calculations.

Radiation Dose Index Monitoring Systems (RDIMs) can report and track estimated organ and effective doses from CT scans. However, the methods to estimate these doses are not standardized. The purpose of this initial study was to a...

Tractography has become more widely used in neurosurgical planning, yet traditional voxel-based Region of Interest (ROI) segmentation often includes anatomically implausible fibers and becomes challenging with distorted anatomy n...

To evaluate the accuracy of the Analytical Anisotropic Algorithm (AAA) and Acuros XB (AXB) implemented in the Eclipse treatment planning system for small-field dosimetry in low-density lung, with emphasis on their performance in...

To assess the effect of virtual monoenergetic image (VMI) energy variation (50-160 keV) on the accuracy of auto-generated contours using commercial autocontouring software.

Universal CT number to mass density (CTN-to-MD) curves in large hospital networks with multiple CT simulators and treatment planning systems reduces the potential for error during photon treatment planning. The goal of this study...

Film is typically read using a flatbed scanner, but these scanners are prone to Type A errors (orientation, placement, etc.). We compare dose calibration of EBT4 radiochromic film from 6MV exposures using a flatbed film scanner a...

Dual Energy Computed Tomography (DECT) is readily available in some clinical settings, enabling image visualization at multiple energy levels to extract material-dependent attenuation differences. This ability enables improved ti...

Computed tomography-derived pulmonary perfusion (CTQ) imaging is an emerging, accessible modality that derives regional pulmonary perfusion information from CT datasets. To facilitate clinical translation of this new technology,...

Accurate 177Lu SPECT quantification is essential for patient-specific dosimetry in radiopharmaceutical therapies. Monte Carlo (MC) based reconstruction uses comprehensive system modeling to stochastically simulate photon transpor...

To enhance the image quality of low-resolution 3D cine magnetic resonance (MR) images acquired at 2Hz by applying two single-image super-resolution deep-learning neural networks, so that the enhanced 3D cine images serve as bette...

Toxicities to organs remain a critical limitation to dose escalation in radiotherapy. Ion radiotherapy reduces the absorbed dose to normal tissue but is characterized by a higher relative biological effectiveness (RBE). Existing...
