Representation apparatus

A medical imaging device configured to provide medical image data for generating an augmented reality or virtual reality, the medical imaging device comprising:

• a projector configured for projecting a light pattern onto a surface of an examination subject;
• wherein the light pattern includes a defined projection geometry relative to the projector;
• wherein the projector is configured to provide the defined projection geometry to a first representation apparatus;
• and
• the first representation apparatus configured for representing a first augmented reality, a first virtual reality, or the first augmented reality and the first virtual reality, the first representation apparatus including a camera unit configured for mapping, at least in segments, the examination subject arranged in a direction of view of the first representation apparatus, wherein the camera unit is further configured for mapping the light pattern that is projected onto the examination subject by the projector, wherein the first representation apparatus is configured for adjusting a representation of the first augmented reality, the first virtual reality, or the first augmented reality and the first virtual reality using the mapped light pattern and the defined projection geometry.

A method for registering a representation apparatus configured to provide an augmented reality or virtual reality with an examination subject, the method comprising:

• projecting a light pattern onto a surface of the examination subject using a projection unit, wherein the light pattern includes a defined projection geometry relative to the projection unit;
• mapping, at least in segments, of the light pattern that is projected onto the surface of the examination subject by a camera unit;
• determining a transformation instruction between a coordinate system of the representation apparatus and a coordinate system of the examination subject using the mapped light pattern and the defined projection geometry;
• and
• adjusting a representation of the augmented reality or the virtual reality as a function of the transformation instruction.
