Issue Date: | 2007 | Journal: | Progress in Biomedical Optics and Imaging - Proceedings of SPIE | Conference: | Medical Imaging 2007: Ultrasonic Imaging and Signal Processing | Abstract: | Ultrasound elastography measures the elastic properties of soft tissues using ultrasound signals. The elastic problem can be analyzed with tensor signal processing. In this work, we propose a new interpretation of elastography through the deformation tensor and its decomposition into both the strain and vorticity tensors. Vorticity gives information about the rotation of the inclusions that might help in the discrimination between malign and benign tumors without using biopsy. Although clinical validation is needed, synthetic experiments present reliable results. | URI: | http://hdl.handle.net/10553/47439 | ISBN: | 081946631X | ISSN: | 1605-7422 | DOI: | 10.1117/12.709251 | Source: | Progress in Biomedical Optics and Imaging - Proceedings of SPIE[ISSN 1605-7422],v. 6513 (65130K) |
