Left ventricle volume estimation from 3D SPECT reconstruction

Our approach describes the three-dimensional reconstruction of the internal and external surfaces of the human's left ventricle from actual SPECT data. The reconstruction is a first process fitting in a complete VR application that will serve as an important diagnosis tool for hospitals. Beginning with the surfaces reconstruction, the application will provide volume and interactive real-time manipulation with the model. We focus on speed, precision and smoothness for the final surfaces. We present several recoveries with non-missing data and partial missing data, performed using different fillings for a PHANTOM test volume. We also present a reconstructed cardiac cycle from an actual patient data, all along with its associated ejection fraction estimation.
