Abstract: Devices, systems, and methods for controlling an intravascular imaging device are provided. For example, in one embodiment a method includes communicating a control signal to an actuator of the intravascular imaging device to cause oscillation of an imaging element of the intravascular imaging device, wherein the intravascular imaging device further includes an acoustic marker; receiving imaging data from the imaging element of the intravascular imaging device; identifying the acoustic marker in the imaging data by determining a correlation between the imaging data and a template representative of the acoustic marker; adjusting an aspect of the control signal based on identifying the acoustic marker; and communicating the adjusted control signal to the actuator of the intravascular imaging device.

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.
