Abstract

Volumetric echocardiography can potentially give a more complete picture of cardiac dynamics than its two-dimensional (2D) counterpart. Current clinical volumetric imaging probes have relatively low frame rates, and often require ECG gating to stitch together an entire volume. This makes measuring fast dynamics of the heart as well as imaging patients with irregular heartbeats difficult. We have previously designed and manufactured 2D sparse arrays with elements seeded in a density-tapered spiral pattern for cardiac imaging. Using these prototypes, we demonstrate in this paper the first high-frame-rate volumetric closed-chest porcine cardiac as well as open-chest myocardial blood flow results. These preliminary results suggest the potential of performing high-frame-rate volumetric cardiac imaging using the sparse spiral arrays.
