Embodiment Construction

[0062] as attached figure 1 As shown, the ultrasound probe 1 is connected to the combination device 5 via an image data connection 10 . An image data connection 10 is connected to the interface 9 for receiving ultrasound image data. The image of the object 3 is displayed on a display device (for example a screen 6 ), which is connected to the combination device 5 . The combining device 5 may be a computer, such as a personal computer, and may be used to perform a partial alignment of different image data and / or different images.

[0063] Ultrasound probe 1 generates first image data of object 3 and transmits the first image data via image data connection 10 to combining device 5 . The combination device 5 includes a data store 4 containing data that has been previously provided by the stand-alone device ( figure 1 The second image data generated by (not shown in). The combining device 5 is used to combine the first and second image data and display them on the screen 6 . ...

Abstract

The invention relates to the registration of ultrasound image data of an object and of three-dimensional second image data, e.g. from Computed Tomography (CT) or Magnetic Resonance Imaging (MR) of the object. It is proposed to support a manual registration by an automatic process. Reference information defining a reference location (36b) in the ultrasound image (33) are used, wherein the reference location (36b) is located on a surface of the object or is located at a defined distance to the surface of the object when the ultrasound detector generates the ultrasound image data. At least one surface point (36a) on the surface (34) of the object or at a defined distance to the surface (34) is identified in the second image (31). The ultrasound image data and the second image data are aligned with respect to one registration direction using the reference information and using information concerning a location of the surface point (36a) in the second image (31).

Description

technical field [0001] The invention relates to the registration of first image data and second image data of an object. The first image data are generated or have been generated by an ultrasound (US) probe. In particular, US image data is (locally) two-dimensional. The second image data is (partially) three-dimensional image data. Background technique [0002] The subject matter of this application may be combined with and / or augmented with the subject matter of the following two patent applications, U.S. Patent Application Serial No. 10 / 815,759, filed April 2, 2004 filing, and European Patent Application No. 03008448.7, filed on April 11, 2004. The subject matter of these two patent applications is hereby incorporated by reference. [0003] In order to be able to compare images or combine images, the content of the images must be inaligned. This is generally not the case if the different image data are produced by different detectors and / or at different times. The pr...
