Abstract
In a method for transformation of a 3D representation of a part of a body, a central axis of the part of the body to be represented is defined, and a transformation surface that is axis-symmetrical to the central axis is defined. The transformation surface is transformed into a plane and a transformation of the voxels representing the part of the body oriented to the transformed transformation surface is carried out.
Claims20
A method for transformation of a 3D representation of a part of a body, the method comprising:
- defining a central axis of the part of the body;
- defining a transformation surface that is axis-symmetrical to the central axis;
- spatially assigning voxels representing the part of the body to the transformation surface, wherein the spatially assigning is undertaken in a radial direction outwards from the central axis;
- applying an unfolding transformation to the transformation surface and the voxels assigned to the transformation surface, wherein
- the transformation surface is unfolded in a plane and the voxels maintain their spatial assignment to the unfolded transformation surface.
A transformation facility, comprising:
- an axis-positioning unit configured to define a central axis of a part of a body to be represented;
- a surface-positioning unit configured to define a transformation surface that is axis-symmetrical to the central axis;
- an assignment unit configured to spatially assign voxels representing the part of the body to the transformation surface, wherein the voxels representing the part of the body are assigned to the transformation surface in a radial direction outwards from the central axis;
- and
- a transformation unit configured to apply an unfolding transformation to the transformation surface and to the voxels assigned to the transformation surface, wherein
- the transformation surface is unfolded in a plane and the voxels maintain their spatial assignment to the unfolded transformation surface.
An apparatus for transforming a 3D representation of a part of a body, the apparatus comprising:
- a memory storing computer readable instructions;
- and
- at least one processor configured to execute the computer readable instructions to cause the apparatus to
- define a central axis of a part of a body to be represented,
- define a transformation surface that is axis-symmetrical to the central axis,
- spatially assign voxels representing the part of the body to the transformation surface, wherein the voxels representing the part of the body are assigned to the transformation surface in a radial direction outwards from the central axis, and
- apply an unfolding transformation to the transformation surface and to the voxels assigned to the transformation surface, wherein
- the transformation surface is unfolded in a plane and the voxels maintain their spatial assignment to the unfolded transformation surface.
