Project Description:

Our project, ER-SEE-P, focuses on developing an advanced ultrasound-based visualization system to assist in the Endoscopic Retrograde Cholangiopancreatography (ERCP) procedure, a critical method for diagnosing and treating conditions in the bile and pancreatic ducts. During ERCP, physicians often face challenges due to limited visualization from current side-viewing endoscopes, which provide only surface-level imaging and require prolonged cannulation attempts. This can lead to complications such as pancreatitis, tissue trauma, and excessive radiation exposure. We propose a forward-facing curvilinear phased array transducer designed to be attached to the tip of a sphincterotome, providing real-time, detailed imaging of the major duodenal papilla and surrounding ducts. The transducer is miniaturized to fit within the existing ERCP equipment, with a diameter of less than 5 mm, and is capable of visualizing tissue structures at depths of up to 15 mm. By offering direct visualization, our device aims to reduce the need for blind probing, enhance guidewire placement accuracy, minimize procedure time, and lower radiation exposure.
