摘要： The invention relates to a method of reconstructing images from cone beam projection data from an examination zone (3) of an object to be examined. The cone beam projection data is acquired by means of an X-ray device which includes an X-ray source (1) and an X-ray image intensifier (2), the X-ray source (1) being guided along a trajectory around the examination zone (3) in order to acquire the projection data. First projection data are then acquired from the examination zone (3) in a first mode of operation of the X-ray image intensifier (2) which involves a low resolution. For a sub-zone (4) of the examination zone (3) second projection data is acquired in a second mode of operation of the X-ray image intensifier (2) which involves a high resolution. Subsequently, the first and second projection data is combined so as to form third projection data. The third projection data is represented by the second projection data in the sub-zone (4) of the examination zone (3) and by the first projection data in the remaining part (3a) of the examination zone (3). The images are reconstructed on the basis of the third projection data. The invention also relates to a corresponding X-ray device, notably a C-arm X-ray device.

摘要： The invention relates to an X-ray apparatus which includes an X-ray source (2) for the emission of a conical X-ray beam and an X-ray detector (3) for the multiple detection of the X-rays after their passage through an object to be examined, being arranged along an object axis (4), while the X-ray source (2) and the X-ray detector (3) are displaced along a trajectory. In order to increase the size of the reconstructable examination zone without increasing the size of the X-ray detector, and in order to minimize the problem caused by projections truncated in the transverse direction, the invention proposes an X-ray apparatus which includes means (12, 14, 15) for changing the position and/or the orientation of the X-ray detector (3) relative to the X-ray source (2) and a control unit (11) for displacing the X-ray source (2) and the X-ray detector (3) along the trajectory and for controlling the position and/or the orientation of the X-ray detector (3) during the detection of the X-rays.

摘要： Determining the internal structure of a body, for example, a human body, by means of an electric field which extends between individual electrodes of an electrode array which at least partly surrounds the body. Each time the value of the currents flowing through the individual electrodes is measured. From the currents electrical resistance values in individual tubes of flux generated between the electrodes are measured. By exposure of the body successively to electric fields which each have a different direction and by measurement of the resistance values then occurring, the specific resistance in individual elements of a matrix which is imagined to be stationary with respect to the body can be determined. From the given distribution of the specific resistance in the elements of the matrix, resistance values are calculated in all tubes of flux successively at least once for each field direction. For determination of a correction for the specific resistance in the elements of the matrix, the calculated resistance values are compared with the measured resistance values. The magnitude of the difference determines the magnitude of the correction.

摘要： A network computer system in which the individual processors are arranged in the form of a matrix, with each processor connected with its directly neighboring processors. The individual processors are checkerboard-like assigned to one of two groups, and each group is connected, by its own instruction line, to a control unit for connection to the control computer. The system is useful in performing iterative calculations in which the processors of the one group calculate new values on the basis of initial data previously calculated by the directly adjacent respective processors of the other group.

摘要： An electron beam computed tomography system is provided that uses a cone beam geometry to generate truly three-dimensional images. The required cone beam projections can be obtained using a single sweep of the electron beam along the target ring (20). The target ring (20) is non-planar and shaped roughly like a ⅝th segment of the boundary curve of a saddle. The resulting source trajectory satisfies Tuy's completeness condition with respect to a sizeable volume of interest around the isocenter of the system. The detector (28) has a large area and is built from a plurality of small, brick-shaped detector modules (32), which are placed side by side along a detector trajectory that is a mirror image, through the isocenter, of the source trajectory. Owing to the special shapes of the target ring and the detector strip, a cone-beam of x-rays starting from the target ring and heading towards the opposite segment of the detector strip is not blocked by other portions of the detector.

摘要： A 3D image of a region of an object is computed from truncated cone beam projection data acquired with an x-ray device and a prior CT image representing a larger region of the object. The truncated projection data are extrapolated to derive pseudoprojection data associated with projection directions outside the detector, and an intermediate CT image is reconstructed based on the truncated projection data completed with the pseudoprojection data. The prior CT image is then registered with the intermediate CT image. Forward projection data associated with projection directions outside the detector are computed from the truncated projection data and the registered prior CT image. The 3D image is finally reconstructed based on the truncated projection data completed with the forward projection data.

摘要： The invention enables the temporal variation of the magnetic field generated by a gradient coil to be derived from the measured temporal variation of the current through this gradient coil and from a pulse response which has been determined once and stored for the relevant coil. In this case an inexpensive non-linear amplifier may be used in the gradient channel, and also a gradient coil with eddy current effects, without the reconstruction or the pulse design being degraded.
