Precise guiding and visualization of balloon catheter using photoacoustic imaging
Abstract
We conduct a pilot study using photoacoustic imaging (PAI) technique as a new catheter guiding method. The ex vivo experiment was implemented with three different states of balloon catheter consist of no injection, air injection, and pure water injection. A simple surface removing method was applied to catheter signal extraction. The high-resolution maximum amplitude projection (MAP) images were achieved as results of the experiment.
