Description

Form system | x-ray images - images

The model is useful. It relates to medical technology and can be used both for operational and long-term zagnosti.

Currently, radiography is used for diagnostics in dentistry, and due to the low sensitivity of the photo-exposure, the patient receives a noticeable dose of x-ray radiation during the study. In addition, the process of obtaining an x-ray image is technologically extended in time, which deprives it of efficiency.

Known devices using x-ray detectors and converting x-ray radiation into a television signal.

The most technical one is the claimed one: / useful model, is a system with a television X-ray detector (Synchrotron Radiation News, .1990, v, 3, N 4, p.17-22), containing a fiber fiber washer applied to its surface a layer of the phthomophore facing the object under study, an image enhancer, a coordinate sensitive detector, a processing system in which information is stored, processed, and the resulting images are displayed on a monitor screen and on with a printer.

The Odaako-Tazana system, in terms of its design features, (dimensions, location of the high-voltage amplifier, in the immediate vicinity of the phosphor layer) allows it to be used ONLY for outdoor studies or for in vitro studies.

The basis of the claimed useful mode § / 5 was the task of creating a fluoroscope with a remote receiving element, which allows to perform diMKM 5 - A 61 in 6/02, Н 04 N 5/321 in its dimensions and other characteristics

agnostic B oral cavity.

 To solve this problem in the X-ray image forming system

containing a fiber washer with a phosphor layer5 deposited on its surface facing the object under study, an image enhancer, a coordinate-sensitive detector and a processing electronic system, according to the invention, two or more fiber optical fibers are sequentially installed at an angle to each other between the fiber washer and the image intensifier . Additionally, in order to meet the requirements of hygiene, sterility and tightness, a fiber washer with a phosphor layer deposited on it, fiber optic fibers, image enhancer and coordinate-sensitive detector are placed in a disposable hygiene case. As a material for the cover, a material that is transparent to x-ray radiation can be used, on the one hand, and on the other hand, which meets the requirements of hygiene, sterility and tightness. lavsan.

The drawing shows a structural diagram of the inventive system, containing the layer I of the phosphor deposited on the surface of the fiber washer 2, which is connected to sequentially located at an angle to each other fiber optic fibers 3,4,5. The fiber optic fiber 5 is connected to an amplifier 6 of the image, connected through a fiber washer (not shown in the diagram) to a coordinate-sensitive detector 7 connected to the processing electronic system 8 based on a semiconductor memory structure (CCD), and fiber washer 2 with an applied layer I of the phosphor, fiber optical fibers 3,4.5, amplifier 6 and the coordinate-sensitive detector 7 together form the adjacent part of the fluoroscope, which is placed in a gigiyeshskoy cover 9 disposable.

The system is working. in the following way. The preliminary receiving part of the fluoroscope, placed in a disposable hygiene cover 9, is placed in the patient’s oral cavity by placing a phosphor layer in the immediate vicinity of the studied object (tooth), and the x-ray source is properly set. The X-ray pulsed radiation passes through the object under investigation and enters the layer I of the luteophosphor, in which the X-ray image is converted to optical. Then this image is fed through a fiber washer 2 and optical fibers 3,4,5 to an image amplifier 6 and then to a CCD matrix of a coordinate-sensitive detector 7. Here, the optical image is converted into a video signal, which is processed by an electronic system 8, including an interface the input of which is connected to the output of the detector 7, and the output is connected to a computer in which the signal is stored, processed and the resulting images are presented in a form convenient for the researcher on the monitor screen and printer connected to a computer.

So, the use of the claimed system. . allows you to:

reduce the dose of x-ray due to the high sensitivity of the recording equipment by 3-4 orders of magnitude compared with radiation in traditional radiography;

get the result directly during the study:

use additional shformation followed by more detailed image processing.
