| 20090304253 | METHOD OF PROCESSING RADIOLOGICAL IMAGES, AND, IN PARTICULAR, MAMMOGRAPHIC IMAGES - A method of processing a radiological image of an organ. The method may comprise generating a recombined image (R) from at least one previously acquired low energy image (L) and one high energy image (H) of a portion of the organ. The recombined image comprises a background and one or more areas corresponding to the presence of a contrast medium in the organ. The method may further comprise correcting the recombined image (R) by compensating (C) for the nonuniformities present in the background to obtain a compensated recombined image in which the background has a substantially uniform grey level. | 12-10-2009 |

| 20110157154 | SINGLE SCREEN MULTI-MODALITY IMAGING DISPLAYS - Methods and systems provide an integrated display, on a single screen, of images obtained from multiple modalities used in screening a subject. The methods and systems are usable with 2D, 3D, and 4D imaging, by which a single screen displays a screen image from a first modality. A window delineating an area of interest is placed on a first modality image from the first modality, and this area of interest is then displayed on a second modality image from a second modality, thereby providing a combined image representing the area of interest through both modalities. Preferably, the first modality image corresponds and/or is correlated with the second modality image. | 06-30-2011 |

| 20110019891 | MEDICAL IMAGING PROCESS FOR TRIPLE-ENERGY MODELING, AND DEVICE FOR IMPLEMENTING SUCH A PROCESS - A method for X-ray imaging of a body using an imaging device comprising an image sensor and an X-ray emitter which operates at different emission spectra, wherein the method includes: acquiring a first image resulting from the passage through the body of X-rays emitted by the X-ray emitter with a first emission spectrum; calculating characteristics of the body on the basis of the first image, and calculating a second and a third emission spectrum based on the characteristics of the body, wherein the first, second and third emission spectra are distinct from one another; acquiring a second and third image resulting from the passage through the body of X-rays emitted by the X-ray emitter with the second and third emission spectrum respectively; and modeling the body by generating thickness charts for different materials comprising the body on the basis of the three images. | 01-27-2011 |
