Automated Assessment of Image Quality and Dose Attributes in Clinical CT Images
(2016)Computed tomography (CT) is a valuable technology to the healthcare enterprise as evidenced by the more than 70 million CT exams performed every year. As a result, CT has become the largest contributor to population doses ... -
Cone Beam Computed Tomography Image Quality Augmentation using Novel Deep Learning Networks
(2019)Purpose: Cone beam computed tomography (CBCT) plays an important role in image guidance for interventional radiology and radiation therapy by providing 3D volumetric images of the patient. However, CBCT suffers from relatively ... -
Correlated Polarity Noise Reduction: Development, Analysis, and Application of a Novel Noise Reduction Paradigm
(2013)Image noise is a pervasive problem in medical imaging. It is a property endemic to all imaging modalities and one especially familiar in those modalities that employ ionizing radiation. Statistical uncertainty is a major ... -
Development of a Method to Detect and Quantify CT Motion Artifacts: Feasibility Study
(2022)Artifacts are known to reduce the quality of CT images and can affect statistical analysis and quantitative utility of those images. Motion artifact is a leading type of CT artifact, due to either voluntary or involuntary ... -
Implementing a Continuous Quality Improvement Program in a High-Volume Clinical Echocardiography Laboratory: Improving Care for Patients With Aortic Stenosis.
(Circ Cardiovasc Imaging, 2016-03)BACKGROUND: The management of aortic stenosis rests on accurate echocardiographic diagnosis. Hence, it was chosen as a test case to examine the utility of continuous quality improvement (CQI) approaches to increase ... -
Scatter Correction for Dual-source Cone-beam CT Using the Pre-patient Grid
(2014)<bold>Purpose</bold>: A variety of cone beam CT (CBCT) systems has been used in the clinic for image guidance in interventional radiology and radiation therapy. Compared with conventional single-source CBCT, dual-source ... -
Spatial Coherence-Based Adaptive Acoustic Output Selection for Diagnostic Ultrasound
(2022)The US Food and Drug Administration (FDA) provides guidelines for maximum acoustic output for diagnostic ultrasound imaging through metrics such as intensity, Mechanical Index (MI), and Thermal Index (TI). However, even ...
