Abstract
A system for visualizing one or more bubbles formed by a catheter, the system includes a fluid container, a pulse generator, a schlieren imaging assembly, and a processor. The fluid container is configured to: (i) contain a fluid, and (ii) receive into the fluid the catheter having one or more electrodes. The pulse generator is configured to apply one or more pulses to at least one of the electrodes. The schlieren imaging assembly is configured to acquire schlieren images of the bubbles occurring in the fluid when applying the one or more pulses, and the processor is configured to visualize the bubbles using the schlieren images.
