摘要： A method for determining the presence or absence of malignant features in medical images, wherein a plurality of base comparison or training images of various types of lesions taken of actual patient is examined by one or more image reading experts to create a first database array. Low-level features of each of the lesions in the same plurality of base comparisons or training images are determined using one or more image processing algorithms to obtain a second database array set. The first and second database array set are combined to create a training database array set which is input to a learning system that discovers/learns a classifier that maps from a subset of the low-level features to the expert's evaluation in the first database array set. The classifier is used to determine the presence of a particular mid- level feature in an image of lesion in a patient based solely on the image.

摘要： The invention relates to a method of analyzing a medium in order to label the zones of said medium as a function of the contents of said zones, which medium is exposed to ultrasound signals. The method includes a step for receiving echographic ultrasound signals by means of a set of elements, thus defining a set of received signals, a step for correlating at least one pair of signals which are received by two elements from among the set of elements and originate from at least one zone of said medium, a step for analyzing the maximum correlation value as a function of the distance between the two elements whereby the correlated signals are received, said analysis step enabling the detection of the presence of a coherent reflector in said zone of said medium, and a step for labeling the zone in conformity with the result of the analysis step. The invention enables a binary image to be formed of a medium wherefrom noisy data originates, the binary values being attributed to the image as a function of the detection of a coherent reflector.

摘要： The invention relates to an ultrasonic medical imaging apparatus intended for analyzing an organic medium potentially including defects within a noisy structure. Ultrasound signals focused at a given depth according to M distinct successive excitations are emitted and an image formation module makes it possible to obtain an image of said depth after reception of responses from the medium. The invention is such that the apparatus includes a module for using said responses for constructing a rectangular response matrix of dimension N*M, a coefficient Knm of which represents the response from the medium received by the transducer n following an excitation m, decomposing said response matrix into singular values, using the singular vectors corresponding to said singular values for locating singular zones corresponding to defects in the medium. Application: Ultrasonic apparatus particularly in the medical field.

摘要： The invention relates to a highly automated puncture system for inserting a cannula or a needle into a blood vessel of a person or an animal. The puncture system has an acquisition module that allows for determining at least a location of a blood vessel underneath of the surface of a skin and is further enabled to determine an optimal puncture location that is potentially suitable for inserting a cannula into the blood vessel. Further, the puncture system has tissue analysis means to analyse the skin surface in the proximity of the punture location to check whether the skin is suitable for punctuation. This prevents puncturing the skin at locations where scars, wound and the like can be found.
