摘要： The stereotaxic images being digitized, a target pixel in a target region of interest is selected, a target window of chosen dimensional characteristics and containing the said target region of interest is generated around the selected target pixel, a set of pixels is determined in a second image, according to a predetermined selection criterion, a second window, of the same dimensional characteristics as the said target window, is generated around each selected pixel, a correlation processing between the grey-scale levels of the pixels of each second window and the grey-scale levels of the pixels of the target window is carried out so as to obtain a correlation value for each second window, and the region of interest homologous to the target region of interest is identified on the basis of the analysis of the set of correlation values thus obtained, so as to minimize the risks of matching error between the homologous regions of interest. The element of interest is then located on the basis of the positions of the two homologous regions.

摘要： The invention concerns radiology systems and, more particularly, in such systems, to a method to determine and calibrate the lumination (namely the quantity of light received multiplied by the exposure time) received by the radiographic film in order to obtain a given blackening of the film. This method consists in carrying out a certain number of calibrations of the radiology system, and then in making a sensitogram of the type of film used. Then, a radiographic shot is taken with an object of a known thickness E.sub.o and, to obtain a reference optical density DO.sub.refo, the optical density DO.sub.m of the shot obtained is measured and compared with DO.sub.refo on the sensitogram to determine L.sub.ref.

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： The calibration method consists in measuring the efficiency D of a detector cell placed behind the object as a function of various phantom thicknesses E.sub.p and various X-ray tube supply voltages V.sub.m. These measurements enable an analytic model D=f(V.sub.m, E.sub.p) to be determined describing the resulting curves. The inverse function of this analytic model can be used for calculating thickness E.sub.p as a function of the measured efficiency D and the known supply voltage V.sub.m.
