Project FFR

Format

SOECS Senior Project Demonstration

Abstract/Artist Statement

FFR (Fractional Flow Reserve) is a clinical measurement that allows the diagnostic of stenosis (narrowing of the blood vessels). It is calculated by dividing the maximum myocardial blood flow in presence of a stenosis by the normal maximum blood flow. Volcano Corps have asked us to provide assistance regarding one of their diagnosis devices, namely the FFR ComboMap System. What is needed is a way for their engineers and testers to validate the accuracy of the system in case there is a change in the algorithm. The intended device is an FFR Calibration System to be used in conjunction with the ComboMap System during verification and validation tests. We will be using LabVIEW as the program and the ELVIS II Board. The LabVIEW program will have an interface that allows the user to choose a specific FFR value. This FFR value will translate into two independent signals for the distal and proximal flow rate. The mean distal flow value will dip depending on the FFR value chosen. The two signals are then displayed in the front interface on a waveform chart. The two signals that are produced will then be outputed from the ELVIS II board to the ComboMap System. These signals will then be tested on the FFR device on the software provided by the client as well as their ComboMap System. Our program will be used as a calibrating device to see if the machine is reading what it is supposed to read.
