摘要： In a method for the processing of radiology images for detection of radiological signs, an algorithm is provided to detect such radiological signs on projections as a function of their contrasts. These contrasts are measured by using the responses of linear differential filters with different scale parameters. The method can be used to color or enhance the intensity of the radiological signs detected as a function of their degree of malignancy. The algorithm may be applied directly to the signal given by the detector.

摘要： An apparatus and method for medical imaging, particularly for mammography, wherein a body organ, such as a breast, is exposed to X-rays and the X-rays are collected after attenuation through the object. The recorded attenuations are processed and displaying a result of this processing in the form of a representation of an image of the object. The processing of the recorded attenuations form includes automatic classification of zones of the breast into pathological or non-pathological classes. The automatic classification takes into account at least one classification input into the apparatus in advance in association with data that can be collected by the apparatus, and using this prior classification as a reference in order to produce a classification of the same type if there is similarity between the collected data and the data associated with this reference classification.

摘要： A method and computer program and device for evaluation of the radiographic image quality of a phantom containing cells with two visualizable objects in which: the coordinates of each phantom cell are determined on each phantom image; for each phantom cell containing at least two objects: a level of a radiographic reference signal is calculated in an area of reference at right angles with the first object whose position in the cell is known; for each area of the cell capable of containing the other object: a search area formed by a set of pixels is defined; for each pixel of the search area: a signal sample is extracted in an area of interest centered on the pixel and of the same size as the reference area; a logarithmic probability function is calculated between the sample and the reference signal, the probability function corresponding to a mathematical observer; a surface parameter of the set of probability values thus obtained is calculated; the area of interest whose surface has a peak is selected as area containing the other object; the image quality score is calculated from the results of detection for the set of phantom cells.

摘要： In a method and apparatus for image processing an algorithm is used to detect radiological signals in a series of 3D data. The algorithm indicates the position of a radiological signs in a digital volume by means of markers. The algorithm has the potential to distinguish automatically between malignant elements and benign elements. The algorithm comprises a fuzzy logic approach to explain the ambiguities in the image. The algorithm is applied directly to the radiography projection images.

The system includes an X-ray source adapted to irradiate the object with a beam of X-rays from a plurality of positions in a sector, an X-ray detector positioned relative to the X-ray source to detect X-rays transmitted through the object and a processor which is adapted to generate a three dimensional image of the object based on X-rays detected by the detector. The detector is adapted to move relative to the object and/or the X-ray source is adapted to irradiate the object with the beam of X-rays such that the beam of X-rays follows in a non arc shaped path and/or a center of the beam of X-rays impinges substantially on the same location on the detector from different X-ray source positions in the sector.
