Paper Abstract

We developed a miniaturized, simple and full field-of-view photoacoustic/ultrasonic endoscopy system, and used a flexible coil to transmit the rotational torque from the rotary stage, which enables a 360o field-of-view imaging in vivo. The developed imaging catheter was fully encapsulated by a single-use protective polyamide tube. A B-scan rate up to 5 Hz (200 A-lines/B-scan) was achieved. Three-dimensional photoacoustic and ultrasound images of the rectum from a SD rat were acquired in vivo. It suggests that this PAE system can be of great interest for clinical translation for a variety of endoscopic applications.
