System and method for modeling a biopsy specimen

摘要

The present disclosure provides, in certain embodiments, a system and method for generating a 3D model of a biopsy specimen. The 3D model may greatly enhance the capability to identify insufficient margins surrounding neoplastic tissue obtained through an excisional biopsy, and improve communication from a pathologist back to a surgeon and/or patient. The model provides a 3D representation of the neoplastic tissue within the specimen, thereby allowing the surgeon (or other medical personnel) to rotate and orient the model at any desired angle to identify insufficient margins and relate the location of the insufficient margins to the removal site to more accurately identify the location at which additional tissue needs to be excised. By identifying the exact location at which additional tissue needs to be excised, the surgeon is able to minimize the amount of additional tissue removed from the patient in order to achieve sufficient margins.

1. A system operable to generate a three-dimensional model of a biopsy specimen that includes a first tissue and a second tissue, the system comprising:
scanning circuitry operable to scan, and generate first coordinate data of, at least a portion of an outer surface of the biopsy specimen; first circuitry operable to generate second coordinate data from two or more slices of the biopsy specimen, wherein the second coordinate data defines an outer edge of the second tissue disposed within any of the two or more slices of the biopsy specimen; and rendering circuitry operable to generate the three-dimensional model of the biopsy specimen from the first and second coordinate data, wherein the three-dimensional model of the biopsy specimen comprises a three-dimensional rendering of the outer surface of the biopsy specimen and a three-dimensional rendering of an outer boundary of the second tissue, wherein the generated three-dimensional model of the biopsy specimen indicates one or more regions where a distance between the three-dimensional rendering of the outer surface of the biopsy specimen and the three-dimensional rendering of the outer boundary of the second tissue is less than a defined distance, and wherein the system is operable to extend at least a portion of the three-dimensional rendering of the outer surface of the biopsy specimen at the indicated regions such that the distance between the three-dimensional rendering of the outer surface of the biopsy specimen and the three-dimensional rendering of the outer boundary of the second tissue is equal to or greater that the defined distance.
