Abstract
In a system, method and workstation, images of a first subject are acquired with an image signal acquisition unit, the position of the image signal acquisition unit is determined, the position of a second subject is determined and the position of the second subject relative to the image signal acquisition unit is also determined and an image of the second subject is mixed into an image of the first subject acquired with the image signal acquisition unit.
Claims16
A system comprising:
- an image signal acquisition unit for acquiring 2D image signals of an examination subject in real time, and an imaging unit for producing a 2D image of the examination subject in an image plane from said 2D image signals;
- an instrument having a tip adapted for interaction with the examination subject;
- a navigation system including a position acquisition unit for determining a position of said image signal acquisition unit and for determining a position of said tip relative to said position acquisition unit;
- and
- a mixing unit connected to said imaging unit for mixing a representation of said tip into said 2D image and, if said tip is not located in said image plane, for determining a distance of said tip from said image plane and for mixing a designation of said distance into said 2D image, said designation being alterable and indicating a magnitude of said distance.

A system comprising:
- a C-arm X-ray image data acquisition unit for acquiring 3D image data of a patient, and an image unit for producing a 3D image of the patient from said image data;
- a support mechanism for support the first subject;
- a position acquisition system for determining a position of said C-arm X-ray image data acquisition unit, said support mechanism, and a medical instrument adapted for insertion into the patient, relative to said C-arm X-ray image data acquisition unit;
- and
- a mixing unit for mixing a representation of the medical instrument into said 3D image of said patient dependent on said position of said C-arm X-ray image data acquisition unit, said support mechanism, and said medical instrument relative to said C-arm X-ray image data acquisition unit.
