1. A surgical system for use in treating tissue of a patient's anatomy at a target site, with a stabilizer and a fixation element, based on patient-specific imaging data, the surgical system comprising:
a localizer to generate patient location data associated with a location of at least a portion of the patient's anatomy;
a display unit to display visual content overlaid onto the patient's anatomy within a field of view observable by a user; and
a computing device coupled to the localizer and the display unit, the computing device comprising one or more processors and a non-transitory storage medium having stored thereon a visualization program that when executed by the one or more processors is configured to:
generate a virtual reference frame,
identify a plurality of different fixation approaches for the fixation element to engage tissue and secure the stabilizer relative to the target site based on the patient-specific imaging data, with the plurality of different fixation approaches including one or more viable fixation approaches,
arrange a virtual viability model within the virtual reference frame based on the patient location data, the virtual viability model comprising one or more viable portions associated with the one or more viable fixation approaches, and
render at least a portion of the virtual viability model in the visual content displayed by the display unit overlaid onto the patient's anatomy within the field of view to assist the user in visualizing the one or more viable fixation approaches.
