Abstract: In many medical applications, it is crucial to match or register two different image data with each other, for example live image data with previously obtained 3D image data. The present disclosure relates to registration of a 3D image dataset with (live) ultrasound data. Rather than reconstructing an image from the ultrasound data and registering the reconstructed image with the 3D image dataset, the approach of the present disclosure matches the ultrasound A mode signals output by an ultrasound transducer with simulated ultrasound A mode signals generated from the 3D image dataset.

Abstract: A system and a computer-implemented method for identifying a region of interest for image registration is provided. The method includes analyzing three-dimensional CT or MRI image data of a tissue to identify one or more structural elements therein and determining a spatial arrangement of the structural elements, accessing first ultrasound image data of the tissue and performing a first image registration of the first ultrasound image data with the CT or MRI image data at a first accuracy, and identifying, based on the spatial arrangement of the structural elements, a region of interest for a subsequent second image registration of second ultrasound image data of the tissue with the CT or MRI image data at a second accuracy that is higher than the first accuracy.
