Description High resolution images are used to track motion of small arteries under application of a static radial pressure. A Fourier based method for tracking both radial and azimuthal motion over a wide dynamic range has been developed. The overall sensitvity of the method has been tested by computer simulation. INTRODUCTION Clinical intravascular imaging to date has focused on defining general features from normal and abnormal studies. Obvious changes in arterial wall properties, such as calcification and dense fibrosis, can be readily identified. More subtle changes, however, have been hard to detect. For this reason, most clinical studies have focused on anatomical measures such as lumen area, equivalent lumen diameter, and wall thickness[1]. Because the circulatory tree is a dynamic mechanical system, low frequency elastic properties of the arterial wall should be measurable if the displacement of the wall can be monitored as a function of arterial pressure. Recent work by several groups ...
