A patient-specific device for guiding resection of a tumor located in local tissue of a patient includes a locator form and a surgical guidance cue. The locator form has a locator-form surface matching a surface of the local tissue of the patient near the tumor's location when the local tissue is imaged in a preoperative position, such that the locator form, when fit to the surface of the local tissue, restores the local tissue to the preoperative position. The surgical guidance cue is integrally formed with the locator form and based on images including only preoperative images of the local tissue in the preoperative position, to indicate a spatial property of the tumor in the preoperative position.

Systems and methods for guiding tissue resection

A method for guiding resection of local tissue from a patient includes generating at least one image of the patient, automatically determining a plurality of surgical guidance cues indicating three-dimensional spatial properties associated with the local tissue, and generating a visualization of the surgical guidance cues relative to the surface. A system for generating surgical guidance cues for resection of a local tissue from a patient includes a location module for processing at least one image of the patient to determine three-dimensional spatial properties of the local tissue, and a surgical cue generator for generating the surgical guidance cues based upon the three-dimensional spatial properties. A patient-specific locator form for guiding resection of local tissue from a patient includes a locator form surface matching surface of the patient, and a plurality of features indicating a plurality of surgical guidance cues, respectively.
