Some imaging strategies in multi-angle spatial compounding (2007)
J. E. Wilhjelm, M. S. Jensen, T. Br, B. Sahl, K. Martinsen, S. K. Jespersen, ...
Multi-angle compound images were generated with four schemes: mean, median, root-mean-square and geometric mean. The in vitro images, based on formalin fixed porcine tissue, were analyzed by visual...
Correlation Between Ultrasound B-mode Images of Carotid Plaque and Histological Examination (2007)
S. K. Jespersen, J. E. Wilhjelm, B. Wiebe, L. K. Hansen, H. Sillesen
This paper reports on a study on 69 patients where image features extracted from B-mode ultrasound images of atherosclerotic plaque in the carotid arteries were compared to histological results...
J. E. Wilhjelm, S. K. Jespersen, J. U. Hansen
A newly developed (off-line) spatial compound scanner was used to scan formalin-fixed atherosclerotic carotid plaques. Forty-eight B-mode images were recorded using 7 insonification angles. All...
Ultrasound Spatial Compound Scanner for Improved Visualization in Vascular Imaging (1998)
S. K. Jespersen, J. E. Wilhjelm, H. Sillesen
A new off-line multi-angle ultrasound compound scanner has been built with the aim of improving visualization of vascular tissue. Images are recorded from 3 to 11 insonification angles over a range...
