摘要： A method includes generating emitted signals using transmitter elements and measuring received signals using receiver elements. The received signals are reflected portions of the emitted signals and the received signals correspond to one or more targets. The method also includes applying a first matched filter to the received signals to determine range information for the received signals, filtering the received signals based on the range information to define filtered signals, and determining calibration parameters using the filtered signals. The method also includes correcting the received signals using the calibration parameters to define calibrated signals and determining angle of arrival information for the received signals using the calibrated signals.

摘要： A method includes, following specification of an initial transformation as a test transformation that is to be optimized, determining a 2D gradient x-ray image and a 3D gradient dataset of the image dataset, carrying out, for each image element of the gradient comparison image, a check for selection as a contour point, and determining an environment best corresponding to a local environment of the contour point and extending around a comparison point in the gradient x-ray image for all contour points in the at least one gradient comparison image. Local 2D displacement information is determined by comparing the contour points with the associated comparison points, and motion parameters of a 3D motion model describing a movement of the target region between the acquisition of the image dataset and the x-ray image are determined from the displacement information and a registration transformation describing the registration.
