摘要： A processing method for images obtained by tomosynthesis comprising acquisition of a plurality of 2D projection images of a region of interest of a patient; reconstruction of a 3D digital image from the acquired 2D projection images. An embodiment of the method is characterised in that it comprises: detection of an object in the reconstructed image; estimation of a thickness limit characteristic of a contrast default of the voxels for a diameter of the object; estimation of the thickness of the object; comparison of the thickness of the object to the thickness limit; and in that if the thickness of the object is less than the thickness limit, the method further comprises application at least to the voxels of the object in the reconstructed image of a multiplicative corrective factor equal to the ratio between the thickness limit and the thickness of the object.

摘要： A method and apparatus for calibrating an apparatus that acquires a sequence of radiographic images and correcting images of an object under observation. For each image of a sequence acquired by the apparatus and for a given frequency of acquisition of the sequence, the apparatus is calibrated by determining the value of the variation of a mean of gray levels in at least one zone of interest of the current image of at least one calibration device, the variation being determined relative to the mean gray level of the first image of the sequence in each zone of interest. The determination of the variation is reiterated for a series of images sequences acquired using calibration devices resulting in first images of mean gray levels different from one sequence to another. Each image of an image sequence of the object under observation is corrected, comprising zones of observation having different gray levels by subtracting from the current image the variation of one gray level relative to the first image of the object, the subtraction being a function of the gray level considered from each zone of observation.

摘要： The invention relates to a method of correcting a digital mammogram of a breast containing an implant. According to the invention, brightnesses situated at and around the implant peak (PI) in the low frequency component of the image (XLP) are attenuated (ATT) as compared with a function (P1) that is applied to the other brightnesses, thereby attenuating the implant.The invention also provides a method of segmenting an implant in a radiographic image, the method being characterized by the following steps: smoothing the image by a noise-reducing lowpass filter, applying a non-directional spatial derivative filter, pixel thresholding, and selecting an outline to define the segmented portion of the image that corresponds to the implant.

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 monolithic accelerometric transducer comprises a fixed part, two mobile mass parts and a resonator having ends fastened to said mobile parts, a flexible frame around the two mobile parts, and two connecting members connecting the frame to the second mobile part and to the fixed part. The frame provides a mechanical filter between the resonator and the fixed part which is not affected by the vibrations of the resonator. The quality factor Q of the resonator is not degraded and the measurement provided by the transducer is more accurate. In a differential output accelerometer, the position of the transducer is deduced from that of another, identical transducer by rotation of 180.degree. about an axis parallel to the resonator, the fixed parts of the transducers being fastened together.

摘要： A method for determining an insertion trajectory of a tool for reaching a moving target object prior to its insertion into a tissular matrix. The method comprises acquiring images of the tissular matrix, constructing a three-dimensional representation of the tissular matrix, determining coordinates of the initial position of the target object and any obstacles, and determining at least one potential trajectory of the tool from the coordinates of any obstacles and the initial position of the target object. The method further comprises simulating insertion of the tool in the tissular matrix to determine displacement of the target object during insertion of the tool up to the initial position of the target object along a potential trajectory, determining a new position of the target object based on the determined displacement, and determining the insertion trajectory for the new position of the target object.
