Ultrasonic System for Material Characterization & Flaw Detection
The utilization of ultrasound imaging is common for material characterization and detection of flaws in small-scale biological tissues and soft materials because it provides quantitative and relevant information. However, this imaging modality relies on the probe coming into direct contact with the soft material in order to minimize excess attenuation...

Vital Signs Monitoring using Depth Cameras
Cardiovascular disease is responsible for an estimated 17.9 million deaths each year, making it the leading cause of death worldwide. Continuous heart health monitoring way is the best preventative for heart failure. However, standard monitoring devices, including ECG and PPG, require direct physical contact, which can be difficult for certain patient...

Head Motion Correction with Soft Pressure Pad for MRI Scans
Addressed Need Head motion remains a major challenge during medical imaging scans, particularly in pediatric and older patient populations. Motion impacts diagnostic image quality, costing both time and money in the clinical setting. In research, motion artifacts can introduce errors into quantitative measurements, especially in high-resolution or...

Novel Decoupling Technique for Multichannel RF Coil Arrays
Magnetic resonance imaging (MRI) is an important non-invasive imaging modality that produces detailed images of organs and tissues in a body. Using high fields, 1.5T, 3T, 7T, and above, provides higher signal-to-noise ratios (SNR), temporal resolutions and spatial resolution. MRI RF coils play a significant role in determining image quality. Surface...

Inflammation Targeting Contrast Agent for MR Imaging
Atherosclerosis is characterized by the formation of fatty plaque deposits within the vasculature. With increasing plaque buildup, the affected arteries may harden and narrow leading to complications such as heart attack, stroke, aneurysm and other cardiovascular events. The complex nature of plaque makes lesion-targeting imaging, and subsequently early...

Seizure Onset Zone (SOZ) Localization from rs-fMRI in Pediatric Epilepsy
Epilepsy is a debilitating disorder that affects 50 million people worldwide, including one in 150 children. About 20-40% of children with epilepsy suffer from refractory seizures despite treatment with anticonvulsants, i.e. pharmaco-resistant epilepsy (PRE), which results in increased morbidity and mortality. Early identification and surgical intervention...

Systems and Methods for Medical Imaging Shape Measurements
There has been much research into developing learning methods on non-Euclidean domains such as point clouds, various meshes and graphs. However, very few have studied CNNs on tetrahedral meshes, which are highly useful in medical imaging applications. Tetrahedral meshes have millions of edges and vertices and existing graph convolutional networks are...

Framework for Enhancing Retinal Color Fundus Images
Non-mydriatic retinal color fundus photography (CFP) is widely used in clinical settings, primarily because it doesn’t require pupillary dilation. However, CFP has quality issues due to operator errors, imperfections and patient-related causes. Further, medical providers often have difficulty collecting paired low-high quality CFP. Most denoising...
