This paper presents an automatic system for the measurement of carotid intima-media thickness (IMT) that is based on the digital processing of ultrasound images. The measurement technique is described in detail, highlighting the advantages compared to other methods and, reporting some experimental results. Finally, an analytical approach is used to estimate the intrinsic accuracy of the system.read more

Review: A state of the art review on intima-media thickness (IMT) measurement and wall segmentation techniques for carotid ultrasound
TL;DR: This review is an attempt to discuss the most performing methodologies that have been developed so far to perform computer-based segmentation and intima-media thickness (IMT) measurement of the carotid arteries in ultrasound images.

TL;DR: It is shown that the algorithm's segmentation is not statistically different from that of a trained operator and that the segmentation error is lower than 1 pixel for both the lumen-intima interface and for the media-adventitia interface.

TL;DR: This work presents a computer aided diagnostic (CAD) based ultrasound characterization methodology (a class of Atheromatic systems) that classifies the patient into symptomatic and asymptomatic classes using two kinds of datasets: plaque regions in ultrasound carotids segmented semi-automatically and far wall gray-scale intima-media thickness regions along the common carotid artery segmented automatically.

Completely Automated Multiresolution Edge Snapper—A New Technique for an Accurate Carotid Ultrasound IMT Measurement: Clinical Validation and Benchmarking on a Multi-Institutional Database
Filippo Molinari,Constantinos S. Pattichis,Guang Zeng,Laura Saba,U. R. Acharya,Roberto Sanfilippo,Andrew N. Nicolaides,J. S. Suri +7 more
TL;DR: The combination of multiresolution CA recognition and far-wall segmentation led to an automated, low-complexity, real-time, and accurate technique for carotid IMT measurement, which can constitute a clinically validIMT measurement for assistance in atherosclerosis disease management.

A multiscale dynamic programming procedure for boundary detection in ultrasonic artery images
TL;DR: A thorough evaluation of the method in the clinical environment shows that interobserver variability is evidently decreased and so is the overall analysis time and the authors conclude that the automated procedure can replace the manual procedure and leads to an improved performance.
