摘要： A method of compensation for the thickness of an organ in an X-ray machine of the type comprising an X-ray source and a detector of the beam of X-rays after it has passed through the organ, the detector being capable of converting the X-ray beam into a digital electronic signal, in which, from a digitized image, an image of the radiologic thicknesses of an organ traversed by the X-ray beam is calculated, a thickness threshold is defined, from this there is derived an algebraic compensation image to bring the pixels of a level below or above the threshold back to the value of the threshold, and the thickness image and a proportion of the compensation image are summed up, to obtain a compensated thickness image.

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.

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.
