Abstract: A digital imaging apparatus and method which includes a radiation source and a sensor arrangement for detecting radiation. The sensor arrangement contains one or more sensors formed of one or more preferably elongated sensor modules, which sensor module contains one or more pixel columns which receive image data. The digital imaging apparatus includes means for positioning the object to be Imaged which is situated within the area between the radiation source and the sensor arrangement, and means for limiting the beam from the radiation source essentially according to the active sensor surface of the said sensor arrangement. Also included is means to move the beam across the object being positioned to be imaged and means to move the at least one sensor belonging to the sensor arrangement in synch with the scanning movement of the beam in order to keep the active sensor surface essentially at right angles to the beam on the plane formed by the scanning movement.

Abstract: 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.

Abstract: 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.

Abstract: The object of the invention is a method and apparatuses used in tissue imaging, in particular for positioning the tissue to be imaged in the imaging area. For example, in mammography the tissue has generally been, among other things, compressed with compression plates and/or even physically pulled into the imaging area. In accordance with the invention, a tissue stretching solution is presented, whereby a tissue stretching means, which comprises a layer of flexible material that is translucent to the energy form, containing image information, used in imaging, is simply, quickly and effortlessly feedable and attachable to the tissue stretching device.
