Paper Abstract

We have successfully developed a fully-sheathed, flexible shaft-based, mechanical scanning photoacoustic endoscopy (PAE) system for imaging the human gastrointestinal tract via the instrument channel of a clinical video endoscope. The endoscopic system uses a single element ultrasonic transducer and flexible shaft-based proximal actuation mechanism, and it has a 2.5 m long and 3.2 mm diameter catheter section, which can be accommodated in the 3.7 mm diameter instrument channel of a clinical video endoscope. Here, we demonstrate the intra-instrument channel workability and in vivo imaging capability of the PAE system.
