摘要： The method comprises a histogram of the radiographed image, i.e., a real histogram, a mathematical model of the image chain and the object obtained by calibration. The mathematical model of the image chain and the object and a set of parameters of acquisition, of the detector, of the positioner and of the object are used to determine two values of gray level, gray min and gray max, delimiting a useful zone and the part below gray min and the part above gray max are suppressed in the real histogram, i.e., a limited histogram. A set of rules is applied to the limited histogram in order to determine the level of brightness (WL) and the contrast (WW) is obtained from the brightness and possibly from one or more parameters selected by the user or fixed a priori.

摘要： A process is disclosed which involves automatic position-finding for a point of interest of an object that exhibits high contrast as compared with surrounding tissues, the process being carried out by means of a stereotactic photographic device that includes a digital image acquisition system. The process includes a number of steps for each image belonging to the pair of stereotactic images. An initial analysis of a histogram of the image pixels are made, and a subsequent determination is made of a threshold corresponding to the difference between the high contrast objects and the surrounding tissues. A subsequent determination is made of the threshold of the image, in order to obtain a binary image incorporating two gray levels. This is followed by the filtering of the threshold determined image in the preceding step, based on morphological criteria of the object in which the point of interest is located. This operation is designed to obtain a segmented projection of the object of interest. This is followed by the localization of the point of interest in the image reference mark. Utilization of the process is for stereotactic examinations performed during mammography.

摘要： A method of image processing in a radiological apparatus includes reconstructing a 3D image of a body from a set of radiography projection images, locating structures presumed to be representative of 3D radiological signs within the 3D image, determining a set of 2D candidate particles corresponding to projections of the presumed 3D radiological signs, assigning, through a fuzzy logic description, to the 2D candidate particles a degree of membership in 2D membership classes of a set of membership classes, each membership class being relative to a type of radiological sign, considering a 2D fuzzy particle being formed by the set of the 2D candidate particles and by their respective degrees of membership in a class, making an aggregate of the 2D fuzzy particles to obtain 3D fuzzy particles in a digital volume, and determining a degree of confidence for each 3D radiological sign from the 3D fuzzy particles.

摘要： A sensor comprises two identical vibrating members operating with a common working frequency and joined to each other by a mechanical decoupling device. The device comprises a frame and two connecting bridges each supporting one member. The frame comprises a succession of mass portions and thinned portions so that the frequency of one mode of structural resonance of the frame is substantially equal to the common working frequency, and each connecting bridge is disposed in a node of vibration of the frame at the common working frequency. Thus, the vibrations of the two vibrating members are decoupled from each other.

摘要： A region of interest is selected in an input image, such as a digital or analog image form a mammography apparatus. Display parameters for the input image or a part thereof are determined as a function of the region of interest. The image or a part thereof is displayed using the determined parameters. Choosing display parameters as a function of the region of interest optimizes the display of the possible region of interest without any adjustment by the operator.
