DEVICES, SYSTEMS, AND METHODS FOR REDUCING SIGNAL NOISE IN ENDOSCOPIC ROTATIONAL IMAGING

The present disclosure includes devices, systems, and methods for reducing signal noise in endoscopic rotational imaging. Many embodiments include an elongate member that includes an impedance matching network disposed between a proximal imaging core and a distal imaging core. In many such embodiments, the elongate member may connect a controller at the proximal end and include a rotational transducer at the distal end. In various embodiments, the proximal and distal imaging cores may include a plurality of insulated conductors disposed within a shield (e.g., a shielded twisted pair (STP)). In various such embodiments, the insulated conductors may be utilized to communicate differential signals between the controller and the rotational imaging transducer. In some embodiments, the insulated conductors in the proximal imaging core may have a larger diameter than the insulated conductors in the distal imaging core.
