Summary:
A new method for 3D reconstruction and quantitative analysis of cardiac cavities based on topographic cellular active contour (TCAC) techniques was developed aiming on-line visualization of cardiac chambers. TCAC algorithms perform boundary contour tracking in video real-time speed on 2D projections taken at different angles by an electronically controlled transducer. The 3D view of the human heart is reconstructed from these contours. The whole process was implemented on the ACE-BOX platform exploiting the power of CNN processors. Performance of TCAC methods was assessed by comparison with manually traced echocardiographic video flows by independent cardiologist experts. For the selected clinical examples, error of our algorithms proved to be comparable to the inter-observer variability between independent experts. Validation of accuracy of volume quantification was performed on 60 in-vitro static objects. The clinical potential of our system is demonstrated by 3D reconstruction of two cardiac chambers with interactive planning of surgical interventions.
