Abstract: A system and method, for obtaining and analyzing vascular data and generating results, that uses vascular test data to determine the state of the vessel. The data and the determinations can be used to generate reports, render diagnoses or identifying ailments, and may do so remotely. The system includes a telemedicine server and may include a number of other modules such as work stations, review tools, data storage modules, etc. The invention allows rapid and efficient analysis of the data, and provides mechanisms for comparing patient data to know or measured normative data sets, remotely if desired, and provides more accurate and less invasive diagnoses based on vascular conditions. The invention permits remote receipt, processing and distribution of the data and diagnoses.

Abstract: A scanning rheometer is presented for the rheological property measurement of electrorheological (ER) and magnetorheological (MR) fluids using a non-linear viscoplastic model, based on the fluid height variation with respect to time. The rheometer basically includes a static (e.g., an overhead reservoir) or a dynamic source of fluid, a channel or slit whose sides form electrodes which are in contact with the flowing ER fluid, or a capillary tube exposed to a static/alternating magnetic field for flowing MR fluids, a transfer tube, either one or two riser tubes, and a column level detector for monitoring the column of fluid as it moves in one of the riser tubes. The column level detector is coupled to a processor which analyzes, among other things, column height vs. time data to determine both viscosity and yield stress. The rheometer overcomes one of the major drawbacks of the conventional rheometer: the inability to produce the yield stress of the ER, or MR, fluid in an absolute zero shear rate range.
