TL;DR: 3D freehand U.S. imaging with 3D B mode and power Doppler ultrasound (U.S.) is a valuable method to quantify in-stent restenoses, particularly in B mode, and it is thus hoped that, in the clinical setting, noninvasive 3D U.s. may provide sufficient precision to grade in- Stent Restenoses.

TL;DR: In this article, a bovine muscle sample was imaged using ultrasound and electrical impedance tomography, and similar speckle patterns were observed, but due to electrical impedance inhomogeneities instead of acoustic ones.

TL;DR: This new anisotropic elasticity-palpography technique was successfully applied to characterize ten coronary plaque and one healthy vessel geometries of patients imaged in vivo with intravascular ultrasound and revealed that the anisotropy index-palPograms were estimated with a good accuracy.

TL;DR: In this article, a dual-modality intravascular imaging system based on fast time-gated fluorescence intensity imaging and spectral domain optical coherence tomography (SD-OCT) was developed for the purpose of interventional detection of atherosclerosis.

TL;DR: The objectives were to compare the performance of a segmentation algorithm, based on the minimization of an uncertainty function, to delineate contours of external elastic membrane and lumen of human coronary arteries imaged with 40 and 60 MHz IVUS, and to use values of this function to delineates portions of contours with highest uncertainty.
