Methods for imaging of strain rate in the heart wall are useful techniques for the quantitative evaluation of regional myocardial function. However, a mechanism of the transitions between myocardial contraction and relaxation is unclear. Except for a method based on ECG triggering, a required high temporal resolution was realized by scanning the heart wall sparsely at the expense of the lateral spatial...
The endothelial dysfunction is considered to be an initial step of atherosclerosis. Additionally, it was reported that the smooth muscle, which constructs the media of the artery, changes its characteristics due to early-stage atherosclerosis. Therefore, it is essential to develop a method for assessing endothelial function and mechanical property of arterial wall. There is a technique to measure...
Atherosclerotic change of the arterial wall leads to a significant change in its elasticity. For assessment of elasticity, measurement of arterial wall deformation is required. For motion estimation, correlation techniques are widely used, and we have developed a phase-sensitive correlation method, namely, the phased-tracking method, to measure the regional strain of the arterial wall due to the heartbeat...
