Classification: CPC A | IPC A

Claim 0:
1. A magnetic-based tracking system for tracking an ultrasound probe to create a three dimensional (3D) visualization, the system comprising:
a reference device including a reference magnet;
the ultrasound probe comprising a magnetometer, wherein the ultrasound probe is configured to capture ultrasound images, wherein the magnetometer is configured to detect magnetic field strengths of a magnetic field generated by the reference magnet, and wherein a position of the ultrasound probe is tracked on a portion of a patient body in relation to the reference magnet;
and a console including a processor and non-transitory computer-readable medium having stored thereon logic that, when executed by the processor, is configured to perform operations including;
receiving the ultrasound images, the magnetic field strengths, and corresponding timestamps for both the ultrasound images and the magnetic field strengths;
pairing the ultrasound images with the magnetic field strengths based on corresponding timestamps for both the ultrasound images and the magnetic field strengths;
and generating the 3D visualization of the portion of the patient body from the ultrasound images by (i) aligning each of the ultrasound images in accordance with ultrasound image-magnetic field strength pairings and (ii) stitching the ultrasound images together in relation to the position of the ultrasound probe on the portion of the patient body.
