摘要： The invention relates to solutions where biased (photoelectric) (semiconductor) material (e.g. Ge, Si, Se, GaAs, HgI, CdTe, CdZnTe, PbI) converts X-ray quanta directly into electron-hole pairs, each of which, by using an intensive electric field connected across said material, can be collected, avoiding lateral diffusion, into the area of its respective pixel. The X-ray quanta are detected and the amount of the ones exceeding the possibly adjustable threshold level is counted. According to the invention the reading electronics (20) may be implemented by providing for each of the pixels (31, 31", ...) its own junction surface (32) which is connected to the said semiconductor material in a manner by which the reading out of them, as well as for enabling the TDI imaging, the counters (23", ...) for each of the pixels (31", ...) can be loaded parallel from the counters (23, 23", ...) for pixels on the same row in the preceding pixel column.

摘要： The invention generally relates to imaging of an object by electromagnetic radiation, especially to digital mammography performed by scanning technique. According to the invention, movement of a digital sensor of a mammography apparatus, synchronized with scanning movement of the beam, is performed by keeping the active surface of the sensor essentially at right angles to the beam, on a plane formed by scanning movement of the beam, while at the same time distance from the sensor to the radiation source is continuously adjusted so that its path in the direction of scanning movement of the beam becomes essentially linear.

摘要： The invention relates to digital scanning imaging by electromagnetic radiation. To reduce the difference between the resolutions in the scanning direction and the direction perpendicular thereto, pixels (P1, P2, P3, P4, P5, P6) in the scanning direction are connected to counters (C1, C2, C3) through switching means (Sm1, Sm2, Sm3) which allow pulses to be directed to the counter of a neighbouring pixel, in addition to its own pixel, for counting, whereby the reading area can be divided into a plurality of 'partial pixels' and by suitably changing the switch positions, it is possible to follow the imaging scan as reading areas formed by the 'partial pixels'.

摘要： The imaging apparatus used in mammography generally having a cassette tunnel ( 17 ) or a similar space for the placement of an image data receiving device ( 14 ') in the imaging area of the apparatus. In such a space or in its immediate vicinity, device ( 19 ) for moving the cassette in the space can be provided, thus making the imaging process in many ways faster and easier to carry out. Such device for moving the cassette can also be utilized in various ways to achieve a more versatile and more accurate use of the imaging apparatus.

摘要： In mammographic imaging, the means used to receive image data are often cassettes with an actual image data receiving medium, such as a film, placed inside the cassette. The cassette is positioned in a cassette tunnel or similar space provided in the imaging area of the imaging apparatus. By having the labeling of the film performed in conjunction with the imaging process itself before removal of the cassette from the cassette tunnel, labeling errors due to the reasons stated above are avoided and working efficiency is improved as the separate operation of labeling of films is left out.

摘要： The invention relates to an automatic exposure control of an imaging implemented by electromagnetic radiation, in particular to prioritizing and selecting several automatic exposure signals in connection with mammography imaging, to be used in such a way that areas having darkened too little would not be left into the image to be formed, at least not in the area of the breast tissue. A selection process of the signals makes up an essential part of the invention, in which signals are selected for the basis of control of imaging parameters according to signal values, and possibly also according to the physical location of the signal sources, on the grounds of the selection criteria according to the invention.

摘要： The present invention relates to automatic exposure control implemented in imaging by electromagnetic radiation, in particular to automatic exposure control in film-based mammography, which is based on a completely new approach as compared with the solutions currently in use, which utilize adjustment curves and/or tables constructed on the basis of empiric tests. The new approach includes modeling into the AEC system the radiation spectra obtainable from the radiation source as a function of its operating parameters and attenuation of the spectrum as the radiation traverses components of the imaging apparatus. By measuring the thickness of the object to be imaged and knowing the initial spectrum and its calculable behavior, a correspondence between the AEC signal and the desired darkening of the image can be achieved which is based on true density of the object being imaged.
