Routine radiation therapy machine quality assurance (QA) relies on multiple independent devices and subjective manual measurements, which can limit efficiency and sensitivity to small mechanical deviations. The purpose of this wo...
To propose a novel calibration equation and computational algorithms for film dosimetry using all three RGB color data.
Describe highlights of organizational changes that allowed for the ramp-up of the radiopharmaceutical trials program at the University of Miami Health System (UHealth)
Requiring a radiation oncologist (RO) to be physically present during online adaptive radiation therapy (ART) constrains scheduling and limits patient access. We have developed and implemented a prescribed workflow to delegate co...
Treatment planning for pancreatic SBRT remains challenging due to proximity and overlap of the target with the critical organs-at-risk (OARs). This study uses RapidPlan-predicted dose volume histograms (DVHs) to guide treatment p...
To develop a computational method for the reconstruction of the spectra of the Cherenkov light transmitted through a fluorescent material from the RGB image data taken by digital color cameras.
Rectal spacers are widely used in prostate stereotactic ablative radiotherapy (SAbR) to reduce rectal dose; however, their value as a practical, planning-oriented QA tool remains underdefined. Using real-world clinical trial data...
To identify factors contributing to an increased trend in near miss gantry collisions and develop an effective mitigation program.
In head-and-neck radiotherapy, relatively large planning target volume (PTV) margins of 5-mm are standardly used to account for setup uncertainty and anatomical variations. However, this comes at the expense of increased dose to...
Ablative hypofractionated radiotherapy(AHRT), including stereotactic body radiotherapy(SBRT) and stereotactic radiosurgery(SRS), achieves tumor control that is not reliably predicted by Linear–Quadratic (LQ) model. Clinical obser...
Robotic bolus has potential to enhance surface dosimetry by reducing air gaps through adaptive surface contouring and providing immobilization for treatment regions. This study evaluated filler materials for a jamming-style robot...
To develop and validate a unified multimodal medical foundation model that combines visual understanding, cross-modal generation (image-text translation), and interpretable reasoning with visual grounding, and to quantify the gai...
MD values quantify visual loss. Through OCT images, physicians can obtain MD values to assess patients' visual status. This task is crucial for early patient screening. However, current AI-based MD prediction methods lack interpr...
In Radiation Oncology, a crucial step for accurate patient treatment is converting Hounsfield Units (HU) from Computed Tomography (CT) scans into mass or electron density for dose calculations. However, several factors – like sca...
To develop and test a four-dimensional (4D) motion model capable of accurately extracting respiratory motion on voxel-by-voxel basis using 4D-CT imaging and deformable image registration (DIR).
A modified lung shunt fraction (LSF) based on conventional 2D planar imaging data was proposed. That modified LSF can reduce the 2D overestimation errors and get closer results with 3D SPECT images.
Fluoroscopy education and clinical literature dealing with videofluoroscopic swallowing studies commonly emphasize frame rate as the primary determinant of temporal resolution and diagnostic accuracy. However, frame integration o...
To determine whether clinical quality metrics and treatment goals previously believed to be achieved using the AAA algorithm remain valid when recalculated with Acuros (AXB) in postoperative spine metastasis treatment using 3D co...
To evaluate the ability of a RefleXion X2 system with extended PET-FOV with a developmental Anchor Point Tracking algorithm to autonomously follow PET-avid target and deliver dose, accounting for large sudden target displacements.
This study aimed to assess three different planning approaches for treating central lung SBRT tumors using GPU Acceleration for optimization and GPUMCD for dose calculation in the Elekta One Planning treatment planning system (v6...
To evaluate the organ equivalent dose (OED) and the excess absolute risk (EAR) of radiation-induced secondary cancers associated with ovarian ablation, a treatment performed for a benign condition, using different radiotherapy te...
To validate whether switching from one AI autocontouring software for organ at risk (OAR) segmentation to another is possible seamlessly in a clinical radiation therapy environment by comparing 1) the number of OARs available 2)...
To assess the feasibility of prostate stereotactic body radiation therapy (SBRT) in patients with unilateral and bilateral hip prostheses across multiple treatment platforms, focusing on image quality, planning feasibility, deliv...
To report on the success of an innovative academic program which provides an educational opportunity for ABR-certified medical physicists interested in obtaining a Ph.D. degree while remaining employed, allowing them to engage mo...
