Abstract: Devices, systems, and methods for controlling the field of view in imaging systems are provided. For example, in one embodiment an imaging system includes a flexible elongate member sized and shaped for use within an internal structure of a patient, an imaging transducer positioned within the distal portion of the flexible elongate member, an imaging marker positioned to be detectable within a field of view of the imaging transducer, and a controller in communication with the flexible elongate member and configured to adjust a control signal of the flexible elongate member based on the detection of the imaging marker in data received from the flexible elongate member in order to achieve a desired field of view for the imaging transducer.
