Abstract: A method for segmenting a target anatomy in ultrasound data. Scan-converted ultrasound data is obtained within a scan-converted space in the Cartesian coordinate system. The scan-converted ultrasound data is transformed to de-scanned ultrasound data within a de-scanned space in the Toroidal coordinate system. The de-scanned ultrasound data is an estimate of the ultrasound data as obtained by an original acquisition procedure. A segmentation of a target anatomy can thus be performed on the ultrasound data in the de-scanned space The resulting segmentation data can then be re-scanned back to the Cartesian coordinate system for display with the ultrasound data.

Abstract: A method for the non-destructive examination of aeronautical parts utilizing a system for acquiring x-ray images of the aeronautical parts, the method including verifying the system for acquiring x-ray images of the aeronautical parts, the verification including the steps of: acquiring an x-ray image of a known reference part including predefined structures, recognizing the predefined structures of the known reference part in the acquired x-ray image, measuring image quality on the basis of the result of the recognition step, wherein the recognition of the predefined structures of the known reference part in the acquired x-ray image includes the steps of: using information extracted from the acquired image in order to produce first structure information, and combining the first structure information with information representing a priori knowledge of the structures, by modelling using a Markov chain, in order to produce second structure information.
