摘要： An apparatus for compensating for drift of the focal spot of an X-ray radiation source used in a tomography system is disclosed so as to maintain a primary collimated beam of radiation emanating from the focal spot aligned with target detectors of the tomography system. A second collimated beam of radiation is produced from the same focal spot and directed along a different axis from the first beam. An array of detectors track the movement of the second collimated beam and produce signals which are used to reposition the collimator used to collimate the primary beam so as to maintain the primary beam substantially aligned with the target detectors.

摘要： In a method for acceptance and stability testing of filmless dental radiographic equipment a test measurement body having a plurality of absorption elements which absorb differently is arranged in the beam path of the X-rays at a defined close distance from a radiation-sensitive sensor. The electric signals obtained from the sensor are fed to a computing unit which processes these to form image value signals which are then fed either directly to a display unit or are firstly compared with prescribed desired image values and, in the case of deviations, fed to the display unit. The test measurement body includes a holder for reproducibly holding a sensor which can be applied intraorally to a patient.

摘要： A CT apparatus for scanning compact structures associated with a larger body uses radiation source producing a reduced field-of-view to simplify construction and reduce exposure of the larger body. Truncation artifacts in the reconstructed image caused by volume elements in the larger body imaged by the radiation beam only for projections at some angles, are reduced by acquiring two projections at two different energies and combining those projections to compensate for the attenuation of the radiation by the volume elements of the larger body.

摘要： The device of the present application is an adhesive surface marker comprising a gel sealed by a casing and membrane structure. The markers of the present invention can include a cavity for receiving imaging materials. The markers provide means for marking patients and diagnostic images taken of those patients through different methods including X-Ray, Computerized Tomography, Positron Emission Tomograph, and Nuclear Magnetic Resonance Imaging among others, retain their shape and size, and do not suffer from water-loss which can lead to reduced density to certain radio-graphic modalities (e.g. MRI).

摘要： An X-ray system scans the vascular portion of a human patient by a series of rapidly pulsed exposures from an X-ray tube rotated continuously through 360 degrees around the patient. The tube emits a cone-shaped beam through the patient to a receptor which generates a corresponding series of two-dimensional video images of the patient from successive angles.

摘要： Methods and apparatus for correcting the effect on image quality of a film processor which develops a radiographic image of a structure of interest on a film having an emulsion is disclosed. Such methods and apparatus include shielding a first portion of the film along one edge from the x-ray energy used for imaging the structure of interest and impressing a first calibrated test pattern on the first portion of the film. The first pattern includes a first calibrated graded stepwise density pattern having density positions. The density pattern is produced by visible light. A first plurality of symbols is located adjacent the first pattern, wherein each symbol indicates the magnitude of one of the density positions. A control film of similar emulsion as the emulsion of the image film is provided and impressed with a second calibrated test pattern along one edge. The second pattern includes a second calibrated graded stepwise density pattern having density positions, which pattern was also produced by visible light. A second plurality of symbols is located adjacent the second pattern, wherein each symbol indicates the magnitude of one of the density positions. The intensity and spectrum of the visible light used for impressing the first and second patterns is adjustable. The film is processed in a film processor to develop the first pattern and the radiographic image of the structure of interest. The control film is processed to develop the second pattern. The performance of the film processor used to develop the film is measured by comparing and noting the symbols associated with those density positions between the first and second patterns which match. Physical parameters of selected portions of the developed image of the structure of interest are measured, such parameters define image quality. These parameters are corrected for the effect of film processor performance by adjusting the values of the measured physical parameters according to the optical density values at the match positions of the first and second patterns.

摘要： The invention relates to a method for imaging a desired object by using a panoramic X-ray radiography apparatus equipped with exposure automatics, the apparatus including an X-ray generator (5), an X-ray tube (6), and an image receptor (8) with its holder (10). The detecting of the cone of rays (7) which has passed through the object, for the purpose of determining the exposure value, is carried out during the imaging at points positioned in each given case at different heights (17) in the cone of rays, by using one or more detectors (1). The positioning can be done either by moving the detector or by activating a certain detector in an arrangement of a number of detectors.
