摘要： In a system of X-ray diagnosis for angiographic examinations, the passage of a contrast medium is detected by its physiological effects such as the rise in the temperature of the cutaneous tissues, by means of thermocouples positioned on the patient's body. The signals from the thermocouples are processed in a device which gives forward motion signals for a panel supporting the patient and signals for triggering the shooting in such a way that the radiological image includes an image of the contrast medium.

摘要： A method and apparatus for positioning a patient with respect to an X-ray installation. An X-ray image is produced at the beginning of the operation and stored in an image memory. The memory is read in order to visualize the X-ray image on a television receiver. The table is displaced to a desired position, and the image in the receiver is decentered so as to reproduce the image that would be observed if an X-ray were taken at the desired position.

摘要： An antiscattering grid for an X-ray imaging apparatus of the type comprising a substrate having a plurality of metallized partitions which together define a plurality of cells distributed over the substrate. The partitions allow passage of the X-rays emitted from a source lying in line with the grid, and absorbing the X-rays not coming directly from this source. The substrate is made of a polymer material that may be formed by radiation curing of a monomer sensitive to this radiation. The substrate may be substantially planar and the partitions may be oriented to form a focused grid.

摘要： A method and apparatus for using a tomography to facilitate the placement of an instrument in a vessel or in an organ of a patient's body wherein a specific or selected region of the patient is defined. X-ray radiation is projected onto the selected region, the X-ray radiation being emitted by the X-ray source of the apparatus. The radiation transmitted to a detector of the apparatus is measured, the detector being positioned in line with the X-ray source. The signals of the selected region are measured by the detector and transmitted for acquisition that stores the image. The acquired signals for the image are transmitted to a display in order to display a projected image of the selected region of the patient in a plane parallel to the longitudinal axis of the patient, such that the time interval between measuring the radiation and displaying the radioscopic image is short enough to allow the instrument to be guided in the patient's body in “real-time”. The method is repeated in order to acquire new projected images of the selected region.

摘要： A method is disclosed for eliminating the diffused radiation in a radiology image. The method fundamentally consists in interposing a mask comprising a finite number of areas absorbent to X-rays between the X-ray source and the object which is to be examined, in detecting the corresponding fundamental image in order to deduce from the areas of the same which correspond to the parts eliminated from the beam a distribution of the diffused radiation throughout the image, and in correcting the fundamental image based on this distribution. The method is particularly applicable to medical radiology.
