US 11,298,051 B2 · Technique for processing patient-specific image data for computer-assisted surgical navigation

Abstract

A technique for processing patient-specific image data for computer assisted surgical navigation. A database is provided including multiple first data sets of two- or three-dimensional image data. Each first data set is representative of first shape data or first biometric data of a skin surface of at least one patient. The method further comprises obtaining, by an optical camera system, a second data set of two- or three-dimensional image data of a skin surface of a particular patient and deriving second shape data or second biometric data of the skin surface from the second data set. By comparing the second shape data or second biometric data with the first shape data or the first biometric data of one or more first data sets, a similarity score is calculated. A signal generated based on the similarity score triggers one of selection and de-selection of a first data set.

A method for identifying a data set associated with a patient for use in computer assisted surgical navigation, the method comprising:

providing a database comprising multiple first data sets of image data obtained by a medical imaging method, wherein each first data set is representative of first geometric data of a skin surface of at least one patient;
obtaining, by an optical camera system, a second data set of image data of a skin surface of a particular patient;
deriving second geometric data of the skin surface of the particular patient from the second data set;
comparing the second geometric data with the first geometric data of one or more of the first data sets to calculate a similarity score for each comparison;
and
based on the similarity score, generating a signal that triggers one of selection and de-selection of one of the first data sets for computer assisted surgical navigation,
wherein the image data are three-dimensional image data,
wherein the first and second geometric data are first and second three-dimensional shape data, respectively, and
wherein the first and second three-dimensional shape data are compared by a shape matching algorithm.
