Development of a testing model for an intraventricular impedance imaging system

Intraventricular impedance imaging (III) is a technique for assessment of cardiac function. Presently, there is a need to develop an in vitro testing system for evaluation of the III system. The aim of the research described here is to develop such a testing device. The device consists of a computerized 3D catheter positioner, a ventricular volume regulator and several ventricle simulators. These modules are controlled by a PC-based custom-built software package. The developed hardware is structured in modules. The testing model will be used for the evaluation of static and dynamic characteristics of the III system.<>
