A navigation apparatus for assisting navigation of a device through tissue comprises processing circuitry configured to receive volumetric medical imaging data representative of an anatomical region, the anatomical region comprising a region of tissue to be traversed by a device; process the volumetric medical imaging data to identify different types of tissue in the region of tissue; determine a position of the device; and process the volumetric medical imaging data to obtain a virtual endoscopic view of at least part of the region of tissue, the virtual endoscopic view comprising a virtual representation of the device in its determined position; wherein the virtual endoscopic view is rendered such as to visually distinguish the identified different types of tissue, thereby assisting navigation of the device through the region of tissue.

Navigation apparatus and method

An imaging data processing apparatus comprises a registration unit configured to obtain a hierarchical registration between a reference data set and volumetric medical imaging data, the reference data set comprising a plurality of anatomical structures, wherein the hierarchical registration comprises an initial registration and at least one further registration, and the at least one further registration is obtained by the registration unit by modifying the initial registration, and a segmentation unit for segmenting at least part of the volumetric medical imaging data in dependence on the hierarchical registration. The initial registration comprises a registration between at least part of the reference data set and at least part of the volumetric medical imaging data, the at least part of the reference data set comprising a first anatomical structure or first group of anatomical structures. The at least one further registration comprises a registration between a subset of the reference data set and at least part of the volumetric medical imaging data, the subset of the reference data set comprising a second, different anatomical structure or second, different group of anatomical structures.
