1. A method for switching between fields of view of an ultrasound probe, the method comprising:
obtaining an anatomical model representing a region of interest of a subject, wherein the anatomical model comprises anatomical information;
establishing a first field of view relative to an ultrasonic probe, wherein the first field of view comprises an initial portion of the region of interest;
obtaining ultrasound data from the first field of view by way of the ultrasonic probe;
identifying a first anatomical feature within the first field of view based on the ultrasound data;
determining a location in digital space of the first field of view relative to the anatomical model based on the first anatomical feature;
establishing a second field of view based on the anatomical model and the first field of view, wherein the first field of view functions as a reference field of view, and wherein establishing the second field of view comprises extrapolating a location of the second field of view with respect to the first field of view based on the first anatomical feature, wherein establishing the second field of view further comprises receiving a user input, wherein the user input indicates a desired field of view that is not a pre-encoded field of view, and encoding the desired field of view as the second field of view into the anatomical model, wherein encoding the second field of view comprises flagging a triangle of a plurality of triangles as one of:
an interior triangle, wherein the interior triangle is within the second field of view and within a safety margin, wherein the safety margin defines an area within the second field of view;
a border triangle, wherein the border triangle is at least partially outside of the safety margin; and
an exterior triangle, wherein the exterior triangle is outside of the second field of view; and
switching from the first field of view to the second field of view.
