Registration of first and second image data of an object
First Claim
1. A method for supporting a manual registration of first image data of an object and of second image data of the object, wherein a) the first image data are generated and/or have been generated by an ultrasound detector, b) the second image data are three-dimensional image data, c) reference information defining a reference location in the first image data are used, wherein the reference location 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 first image data of the object, d) at least one surface point on the surface of the object or at a defined distance to the surface is identified in the second image data, and e) the first and second image data are registered with respect to one registration direction using the reference information and using information concerning a location of the surface point in the second image data.

Abstract
The invention relates to the registration of ultrasound image data of an object and of three-dimensional second image data of the object. It is proposed to support a manual registration by an automatic process. Reference information defining a reference location in the ultrasound image are used, wherein the reference location 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 on the surface of the object or at a defined distance to the surface is identified in the second image. 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 in the second image.

13. An apparatus for supporting a manual registration of first image data of an object and of second image data of the object, comprising:
-
an interface adapted to receive first image data, wherein the first image data are generated and/or have been generated by an ultrasound detector;
an interface adapted to receive second image data and/or a data storage for storing the second image data, wherein the second image data are three-dimensional image data;
an interface adapted to receive reference information defining a reference location in the first image data, wherein the reference location 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 first image data of the object;
an identification device adapted to identify at least one surface point on the surface of the object or at a defined distance to the surface in the second image data and adapted to generate corresponding information concerning a location of the surface point in the second image data, wherein the identification device is connected to the interface adapted to receive the second image data and/or is connected to the data storage;
a partial registration device adapted to register the first and second image data with respect to one registration direction using the reference information and using the information concerning a location of the surface point in the second image data, wherein the partial registration device is connected to the interface adapted to receive reference information and is connected to the identification device. - View Dependent Claims (14)
