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.

Abstract: Disclosed is a computer-implemented method of determining a control parameter for controlling a medical imaging device. The disclosed method encompasses acquiring an operating parameter such as an imaging depth of an ultrasound probe used for imaging an anatomical structure (e.g. an internal organ or bony tissue or cartilage) and using the operating parameter as a guidance for appropriately orienting an x-ray device to generate an image of the same anatomical structure from for example the at least substantially same perspective as the perspective used for generating the ultrasound image. In examples, this is accomplished by using a transformation matrix which is suitable to transform the operating parameter of the ultrasound device into a corresponding control parameter of the x-ray device, or by using an appropriately configured, specifically trained, learnable algorithm such an artificial intelligence algorithm for determining the control parameter of the x-ray device.
