1. A system for planning a medical procedure, the system comprising:
a processor; and
a memory operably coupled to the processor and storing instructions that, when executed by the processor, cause the system to perform operations comprising:
receiving a three-dimensional model of an anatomic region of a patient, and
evaluating whether the three-dimensional model is suitable for use in a registration procedure to be performed in the anatomic region, wherein the evaluating comprises—
analyzing a span of the three-dimensional model along at least two different directions,
determining whether the three-dimensional model includes at least one segmented component corresponding to at least one structure of the anatomic region, and
performing a registration between the three-dimensional model and a virtual registration data set.
