1. A system for image registration, the system comprising:
at least one processor in communication with:
a beamforming ultrasound probe configured to receive and transmit ultrasound signals, and
an ultrasound transducer disposed on a medical device comprising a distal end and an axis, the ultrasound transducer having a predetermined spatial relationship with respect to the medical device, wherein the predetermined spatial relationship comprises a position of the ultrasound transducer relative to the distal end or an orientation of the ultrasound transducer relative to the axis;
the at least one processor configured to:
control the beamforming ultrasound probe to (i) obtain a live stream of ultrasound images of an anatomy and (ii) at least one of transmit or receive an ultrasound signal,
determine a location of the ultrasound transducer relative to the beamforming ultrasound probe based on the ultrasound signal received or transmitted by the ultrasound transducer,
receive an ultrasound image of the live stream of ultrasound images,
receive an X-ray image of the anatomy that includes a representation of the medical device,
identify a position of the medical device in the X-ray image,
determine an offset of the ultrasound image of the live stream from the identified position of the medical device in the X-ray image based on (i) the predetermined spatial relationship of the ultrasound transducer with respect to the medical device and (ii) the determined location of the ultrasound transducer relative to the beamforming ultrasound probe, and
register the ultrasound image of the live stream with the X-ray image based on the offset.
