Claim 11:
12. A surgical navigation system configured to process patient-specific image data, the system comprising:
an interface configured to access a database comprising multiple sets of three-dimensional first image data obtained by a medical imaging method, wherein each image data set is representative of first geometric data of a skin surface of at least one patient;
an optical camera system configured to obtain a second data set of two-dimensional or three-dimensional image data of a skin surface of a particular patient; and
a processing unit configured to:
receive a pre-selection of a particular first data set among the multiple first data sets of three-dimensional image data for computer assisted navigation;
derive second geometric data of the skin surface of the particular patient from the second data set;
compare the second geometric data of the skin surface with the first geometric data of the skin surface of the particular first data set to calculate a similarity score for each comparison; and
based on the similarity score, to generate a signal that triggers one of selection and de-selection of the particular first data set for computer assisted surgical navigation.
