Abstract
A medical image data processing apparatus comprises a registration unit configured to perform a non-rigid registration of a first set of medical image data and a second set of medical image data, wherein the registration unit is further configured to determine, for at least one region, a rigid or affine registration that is an approximation of the non-rigid registration.
Claims19
A medical image data processing apparatus comprising:
- circuitry configured to:
- perform a non-rigid registration of a first set of medical image data and a second set of medical image data, wherein each of the first and second sets of medical image data is representative of a scan area or volume, and the performing of the non-rigid registration comprises determining a non-rigid deformation field,
- perform a cluster analysis to automatically determine a plurality of regions of the scan area or volume, such that, for each region of the plurality of regions, the non-rigid deformation field within the region is approximately homogeneous, and
- determine, for each region of the plurality of regions, a respective rigid or affine registration that is an approximation of the non-rigid registration in the region.
