Abstract

The authors have designed a phantom consisting of 2 independent latex balloon chambers to investigate regional left ventricular contractibility. The wall motion of each chamber has different, amplitudes thus simulating a regional dysfunction. This phantom is applicable to different imaging techniques (contrast angiography, 2-D echography, nuclear angiography and nuclear magnetic resonance). The preliminary results show satisfactory reliability and imaging quality as well as low variability of measurements
