Systems and Methods Related to Registration for Image Guided Surgery

A system comprising:

• a non-transitory memory;
• one or more processors coupled to the non-transitory memory and configured to read instructions to cause the system to perform operations comprising:
• accessing a set of model points of a model of an anatomic structure of a patient, the model points being associated with a model space;
• collecting a set of measured points of the anatomic structure of the patient, the measured points being associated with a patient space;
• determining a first plurality of weights for the set of model points respectively based on a target anatomic location;
• and
• registering the set of model points to the set of measured points based on the first plurality of weights to generate a registration.

A method performed by a computing system, the method comprising:

• accessing a set of model points of a model of an anatomic structure of a patient, the model points being associated with a model space;
• collecting a set of measured points of the anatomic structure of the patient, the measured points being associated with a patient space;
• registering the set of model points with the set of measured points to generate a first registration;
• dividing the anatomic structure into a plurality of anatomic areas;
• generating a plurality of area registrations for the plurality of anatomic areas respectively based on the first registration;
• and
• generating a second registration for translating the model space to the patient space using the plurality of area registrations.
