英文摘要	Endoscopy is an essential clinical tool for the diagnosis of gastrointestinal (GI) tract cancer. A photoacoustic system that elegantly combines optical and ultrasound endoscopy advantages by providing high‐sensitivity functional information and large imaging depth is a potentially powerful tool for GI tract imaging. Recently, several photoacoustic endoscopic imaging systems have been proposed and developed. However, the relatively large size and rigid length of the catheter make it difficult to translate them into wide clinical applications; while the existing system of a relatively small catheter, capable of in vivo animal imaging, is unable to acquire full (360°) field‐of‐view cross‐section images. In this study, we developed a photoacoustic/ultrasonic dual‐modality endoscopic system and a corresponding miniaturized, encapsulated imaging catheter, which provides a full 360° field‐of‐view. The diameter of the catheter is 2.5 mm, which is compatible with the 2.8‐mm instrumental channel of a conventional clinical optical endoscope. Using this system, we demonstrate in vivo 3‐dimensional endoscopic photoacoustic/ultrasonic imaging of the colorectum of a healthy Sprague Dawley rat, by depicting vasculature and morphology of the GI tract. The significantly improved imaging field of view, reduced catheter size, high‐quality imaging results suggest that the developed photoacoustic/ultrasonic dual‐modality endoscopy has a great potential to be translated into a broad range of clinical applications in gastroenterology.
