Model-based intravascular ultrasound elastography visualizes the stress distribution within vascular tissue – information that clinicians could use to predict the propensity of atherosclerotic plaque rupture. However, there are concerns that cluste

It is difficult to produce reliable polar strain elastograms (radial and circumferential) because the center of carotid artery is typically unknown. Principal strain imaging can overcome this limitation, but suboptimal lateral displacement estimates

Imaging plaque microvasculature with contrast-enhanced intravascular ultrasound (IVUS) could help clinicians evaluate atherosclerosis and guide therapeutic interventions. In this study, we evaluated the performance of chirp-coded ultraharmonic imagin

In this paper, we explore the feasibility of reconstructing the mechanical properties of vascular tissues from axial and lateral displacement measurements from Synthetic Aperture (SA) ultrasound images. Modulus values were reconstructed with a soft p

This paper introduces four FPGA-based designs for radiation-tolerant time-of-flight (TOF) systems for sub-atomic particles: Snapshot, Vernier, Fast-Clocking and Hybrid designs. The designs measure TOFs ranging from 0 to 240 ns and are compared based

This paper compares the energy-delay tradeoff curves of 32-bit static barrel and funnel shifters. The Stanford Circuit Optimization Tool (SCOT) is used to determine best transistor sizes in a 90 nm process. The paper evaluates the effect of multiplex

The abnormal growth of the vasa vasorum is characteristic of life-threatening atherosclerotic plaques. Intravascular ultraharmonic imaging is an emerging technique that could visualize the vasa vasorum and help clinicians identify life-threatening pl

Quantitative sparse array vascular elastography visualizes the shear modulus distribution within vascular tissues, information that clinicans could use to reduce the number of strokes each year. However, the low transmit power sparse array (SA) imagi

An imaging system that can detect and predict the propensity of an atherosclerotic plaque to rupture would reduce stroke. Radial and circumferential strain elastograms can reveal vulnerable regions within the fibrous cap. Circumferential stress imagi
