SEGMENTING MEDICAL IMAGE DATA SETS
First Claim
1. A method for segmenting a body structure image data set produced from a medical imaging method, comprising:
- using a reference data set to define delineated body structures in the body structure image data set; and
ascertaining an overall mapping function that substantially maps a reference data set onto the body structure image data set, wherein the overall mapping function comprises a portion that includes a dissection of the body structure image data set into structural parts and their individual rearrangement, and a portion which includes a global deformation and/or shift of the body structures.

Abstract
A method for segmenting a body structure image data set produced from a medical imaging method includes: using a reference data set to define delineated body structures in the body structure image data set; and ascertaining an overall mapping function that substantially maps a reference data set onto the body structure image data set, wherein the overall mapping function comprises a portion that includes a dissection of the body structure image data set into structural parts and their individual rearrangement, and a portion which includes a global deformation and/or shift of the body structures.

9. A computer program embodied on a computer readable medium for segmenting a body structure image data set produced from a medical imaging method, comprising:
-
code that uses a reference data set to define delineated body structures in the body structure image data set; and
code that ascertains an overall mapping function that substantially maps a reference data set onto the body structure image data set, wherein the overall mapping function comprises a portion that includes a dissection of the body structure image data set into structural parts and their individual rearrangement, and a portion which includes a global deformation and/or shift of the body structures.

10. A device for segmenting a body structure image data set produced using a medical imaging method, comprising:
-
a processor;
a data input device for inputting the body structure image data set and a reference data set assignable to the body structure image data set;
a memory for storing the data sets;
segmentation logic stored in memory and executable by the processor, the segmentation logic comprising logic that uses a reference data set to define delineated body structures in the body structure image data set; and
logic that ascertains an overall mapping function that substantially maps a reference data set onto the body structure image data set, wherein the overall mapping function comprises a portion that includes a dissection of the body structure image data set into structural parts and their individual rearrangement, and a portion which includes a global deformation and/or shift of the body structures.

11. A method for segmenting a body structure image data set produced from a medical imaging method, comprising using discontinuous deformation to derive at least a portion of the body structure image data set from a reference data set.
- 12. A method for mapping a reference data set onto a patient image data set to enhance delineations and/or physical features in the patient data set, wherein the patient data set and/or reference data set are separated into regions such that at least one the regions can be individually rearranged relative to other regions in the data set, whereby any twisting and/or shifting of such regions of the patient'"'"'s body relative to the corresponding regions in the patient data set, can be accommodated.
