| Title | Segmentation of arterial vessel wall motion to sub-pixel resolution using M-mode ultrasound. | | Author(s) | Fancourt C, Azer K, Ramcharan SL, Bunzel M, Cambell BR, Sachs JR, Walker M | | Institution | Merck Research Labs, Rahway, NJ, USA. | | Source | Conf Proc IEEE Eng Med Biol Soc 2008.:3138-3141. | | Abstract | We describe a method for segmenting arterial vessel wall motion to sub-pixel resolution, using the returns from M-mode ultrasound. The technique involves measuring the spatial offset between all pairs of scans from their cross-correlation, converting the spatial offsets to relative wall motion through a global optimization, and finally translating from relative to absolute wall motion by interpolation over the M-mode image. The resulting detailed wall distension waveform has the potential to enhance existing vascular biomarkers, such as strain and compliance, as well as enable new ones. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
