摘要： A method of generating layer images from a number of single-shadow images and a device for performing this method. The absorption values associated with the image points of the single-shadow images are stored in a memory. The image value of the layer-image point is formed from the lowest absorption values associated with this layer-image point. Structures or artefacts which are situated outside the layer being imaged can thus be eliminated from the image.

摘要： A tomosynthesis apparatus for the formation of layer images of a body. The apparatus has a large number of radiation source positions which are situated in one radiation source plane. The radiation from the sources in stopped by a diaphragm device so that the radiation beams passing through the diaphragm apertures irradiate a common superposition zone and are incident on a detector surface which is arranged behind the superposition zone. The diaphragm apertures are shaped so that in the detector plane the edge of the radiation beam of each radiation source is at least locally tangent to the edge of a cylinder which is centrally projected onto the detector surface by the radiation source and which is situated within the superposition zone. The axis of the cylinder extends at least approximately perpendicular to the radiation source plane.

摘要： A device for imaging layers of the interior of a three-dimensional object. The object is irradiated from a large number of radiation source positions which are distributed in one plane from this, a coded image of the object which coded image consists of separate perspective images is produced. The coded image is illuminated and imaged by means of an imaging matrix whose imaging elements are distributed in the matrix plane according to the flat distribution of the radiation source positions. Layer images of the object are formed on a photosensitive element by the superposition of the perspective images. For forming different layer images of the object, the imaging elements are positioned in different distributions of changed scale with respect to the distribution of the radiation source positions.

摘要： In a short-time tomosynthesis apparatus for imaging layers of a body to be examined, the body is irradiated by radiation beams from a large number of different directions in order to form perspective images. The radiation beams are detected by a detector which is arranged underneath the body. The perspective images appearing on the exit of the detector will overlap when the radiation beams have a comparatively large angle of aperture. For separating the perspective images, an image separating system is provided at the exit of the detector. The image separating system may comprise a fiber-optical system or an electron-optical deflection unit.

摘要： The invention relates to a method of and a device for forming images of a layer of a three-dimensional object. In order to obtain high-quality images, the object is irradiated by means of a necessarily large number of radiation sources which are arranged in different mutually parallel planes or which are arranged to be displaceable (for example, rotatable) with respect to the object. Alternatively, the object with the record carrier (X-ray film) may be arranged to be displaceable with respect to the radiation sources. In the decoding step (superposition and summing of the shadow images) use is made of the two dimensional distribution of all radiation sources used during coding (irradiation) of the object.

摘要： For the formation of layer images of a three-dimensional object, the object is irradiated from a large number of radiation source positions which are situated in one plane. Thus, a coded image of the object, consisting of individual perspective images, is formed. Subsequently, the coded image is illuminated and the perspective images thereof are superposed for the reconstruction of the object by means of a lens matrix which extends parallel to the plane of the coded image and whose flat lens distribution corresponds to the distribution of the radiation source positions. In the superposition zone of the perspective images, a photosensitive element is introduced in order to form individual layer images of the object. For the formation of the different layer images on the photosensitive element, the lens matrix is displaced in the direction of the optical axis, and the photosensitive element is positioned each time within the depth of focus range of the lenses of the lens matrix.
