A review of explainable and interpretable AI with applications in COVID-19 imaging.
Published in Medical physics
The development of medical imaging artificial intelligence (AI) systems for evaluating COVID-19 patients has demonstrated potential for improving clinical decision making and assessing patient outcomes during the recent COVID-19 pandemic. These have been applied to many medical imaging tasks, including disease diagnosis and patient prognosis, as we...
Adjoint image warping using multivariate splines with application to four-dimensional computed tomography.
Published in Medical physics
Adjoint image warping is an important tool to solve image reconstruction problems that warp the unknown image in the forward model. This includes four-dimensional computed tomography (4D-CT) models in which images are compared against recorded projection images of various time frames using image warping as a model of the motion. The inversion of th...
Technical Note: Dose prediction for radiation therapy using feature-based losses and One Cycle Learning.
Published in Medical physics
To present the technical details of the runner-up model in the open knowledge-based planning (OpenKBP) challenge for the dose-volume histogram (DVH) stream. The model was designed to ensure simple and reproducible training, without the necessity of costly advanced generative adversarial network (GAN) techniques. The model was developed based on the...
Classification of tolerable/intolerable mucosal toxicity of head-and-neck radiotherapy schedules with a biomathematical ...
Published in Medical physics
The purpose of this study is to present a biomathematical model based on the dynamics of cell populations to predict the tolerability/intolerability of mucosal toxicity in head-and-neck radiotherapy. Our model is based on the dynamics of proliferative and functional cell populations in irradiated mucosa, and incorporates the three As: Accelerated p...
Magnetic resonance biomarkers in radiation oncology: The report of AAPM Task Group 294.
...
Published in Medical physics
A magnetic resonance (MR) biologic marker (biomarker) is a measurable quantitative characteristic that is an indicator of normal biological and pathogenetic processes or a response to therapeutic intervention derived from the MR imaging process. There is significant potential for MR biomarkers to facilitate personalized approaches to cancer care th...
Quantitative assessment of ensemble coherency in contrast-free ultrasound microvasculature imaging.
Published in Medical physics
Contrast-free visualization of microvascular blood flow (MBF) using ultrasound can play a valuable role in diagnosis and detection of diseases. In this study, we demonstrate the importance of quantifying ensemble coherence for robust MBF imaging. We propose a novel approach to quantify ensemble coherence by estimating the local spatiotemporal corre...
Shape accuracy of fiber optic sensing for medical devices characterized in bench experiments.
Published in Medical physics
Fiber Optic RealShape (FORS) is a new technology that visualizes the full three-dimensional shape of medical devices, such as catheters and guidewires, using an optical fiber embedded in the device. This three-dimensional shape provides guidance to clinicians during minimally invasive procedures, and enables intuitive navigation. The objective of t...
Fully automated treatment planning for MLC‐based robotic radiotherapy
Published in Medical Physics
Purpose To propose and validate a fully automated multicriterial treatment planning solution for a CyberKnife® equipped with an InCiseTM 2 multileaf collimator. Methods The AUTO BAO plans are generated using fully automated prioritized multicriterial optimization (AUTO MCO) of pencil‐beam fluence maps with integrated noncoplanar beam angle optimiza...
Silicon photomultiplier‐based scintillation detectors for photon‐counting CT: A feasibility study
Published in Medical Physics
Purpose The implementation of photon‐counting detectors is widely expected to be the next breakthrough in X‐ray computed tomography (CT) instrumentation. A small number of prototype scanners equipped with direct‐conversion detectors based on room‐temperature semiconductors, such as CdTe and CdZnTe (CZT), are currently installed at medical centers. ...
