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 an ultrasound imaging system for forming an echographic image of a medium, which system includes a set [REC] of transducer elements [EL] which are operative in a transmission mode and in a reception mode for ultrasound waves, construction means [REB] for constructing echographic signals on the basis of signals [S[1] . . . S[N]] received on the transducer elements [EL], display means [DIS] which are coupled to the construction means [REB] in order to display an image of the medium formed by means of the echographic signals. The construction means [REB] are such that in so-called exclusion zones, in which a coherent reflector is detected and which are determined by determination means [DET], the reception delays [D] are estimated in a manner [INT] other than that [CORR] used for the other zones. The calculation [CAL] of echographic signals is then carried out on the basis of the estimated delays [D[Z],Di[Z}}. The invention enables a correction of phase aberrations and nevertheless offers an excellent lateral resolution, notably in the case of point coherent reflectors.
