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.

Abstract: A method and arrangement for setting a relative position of a radiation device and a patient. The invention relates to the use of radiation therapy for the targeted, selective destruction of tumors.

Abstract: The invention relates to a method of combining first and second image data of an object (3), wherein the first image data of the object (3) are repeatedly generated by an ultrasound detector (1), wherein the second image data of the object (3) are generated separately, for example the second image data have been recorded earlier by a computer tomography, a magnetic resonance or a positron emission tomography imaging device, wherein the first image data are transferred from the ultrasound detector (1) to a combination device (5) and wherein the combination device (5) is adapted to combine the first and second image data of the object (3).

Abstract: The invention relates to a real time radiation treatment planning system for use in effecting radiation therapy of a pre-selected anatomical portion of an animal body according to the preamble of claim 1.
