Method, system and software for the registration of data sets
First Claim
1. A method of registering a first data set with a second data set, including the steps of:
- i) specifying three or more landmarks in a first data set;
ii) specifying three or more corresponding landmarks in a second data set;
iii) registering the first data set to the second data set using the landmarks;
iv) for at least one of the landmarks, determining a first patch around the landmark and a second patch around the corresponding landmark; and
v) refining the registration between the first and second data set using the patches.

Abstract
The present invention relates to a method, system and software for registration of a subject data set with a reference data set. The method of the invention includes the steps of: specifying three or more landmarks (1, 2, 3) in a first data set (8); specifying three or more corresponding landmarks (4, 5, 6) in a second data set (7); registering the first data set to the second data set using the landmarks; for at least one of the landmarks (1), determining a first patch (40) around the landmark (1) and a second patch (43) around the corresponding landmark (4); and refining the registration between the first and second data set using the patches (40, 43). A system and software for registration of a subject data set (7) with a reference data set (8) are also disclosed.

29. A system for registering a first data set with a second data set, including:
-
i) a memory for storing a first and a second data set;
ii) an input device arranged for receiving input which specifies three or more landmarks in the first data set and three or more corresponding landmarks in the second data set; and
iii) a processor arranged for registering the first data set to the second data set using the landmarks, then for at least one of the landmarks, determining a first patch around the landmark and a second patch around the corresponding landmark, and then for refining the registration between the first and second data set using the patches. - View Dependent Claims (30, 37, 38)

31. Software for registering a first data set with a second data set, including:
-
i) a code portion arranged for storing and retrieving a first and second data set from a memory;
ii) a code portion arranged for receiving input which specifies three or more landmarks in the first data set and three or more corresponding landmarks in the second data set;
iii) a code portion arranged for registering the first data set to the second data set using the landmarks;
iv) a code portion arranged for determining, for at least one of the landmarks, a first patch around the landmark and a second patch around the corresponding landmark; and
