Intensifying Screen Explanation: Mavi ve Yeşil renkte üretilen ve özel röntgen filmi. http://en.wikipedia.org/wiki/X-Ray Detectors Photographic plate The detection of X-rays is based on various methods. The most commonly known method are a photographic plate, X-ray film in a cassette, and rare earth screens. A photographic plate or film is used in hospitals to produce images of the internal organs and bones of a patient. They are also used in industrial radiography processes. Since photographic plates are sensitive to X-rays, they provide a convenient and easy means of recording the image. X-ray film is usually provided as pre-loaded paper cartridges with the film inside a light proof paper envelope. An additional paper coated in a thin layer of lead is often included in contact with the photographic film. The lead reflects the x-rays back through the photo film thus more or less doubling the sensitivity of the assembly. Thus the photographic film has to be used the right way round, and is marked as such. The emulsion is frequently coated on both sides of the film or plate in order to increase the sensitivity further. The part of the patient to be X-rayed is placed between the X-ray source and the photographic receptor to produce what is a shadow of all the internal structure of that particular part of the body being X-rayed. The X-rays are blocked by dense tissues such as bone and pass through soft tissues. Those areas where the X-rays strike the photographic receptor turn black when it is developed. So where the X-rays pass through "soft" parts of the body such as organs, muscle, and skin, the plate or film turns black. Contrast compounds containing barium or iodine, which are radiopaque, can be injected in the artery of a particular organ, or given intravenously. The contrast compounds essentially block the X-rays and hence the circulation of the organ can be more readily seen. Many years ago thorium was used as a contrast medium (Thorotrast) — this caused many people to be injured or even die from the effects of the radiation from the thorium. Photographic plates are losing favour in many X-ray facilities because of the necessity to have processing facilities readily to hand, and because the photographic plates themselves, plus the processing chemicals are relatively expensive consumables. http://www.quickmedical.com/wolf_xray/format/ http://www.canyonstate.com/xray-screens/ http://saglikbank.com/ilanlar/ilandetay.asp?id=5503 http://www.quickmedical.com/wolf_xray/format/xray_film.html Wolf X-ray manufactures two speeds of high quality X-Ray Film. Wolf Tru-Blue Film - A high contrast medium speed blue sensitive film with exceptional latitude and low fog. Speed range: 100 with Medium 200 with Hi-Plus (most commonly used for all general radiography procedures). 300 with Light Plus Wolf Green Team Film - For high contrast fine grain x-rays. Approximately twice as fast as Tru-Blue Film. Speed Range: 100 with Rarex BG Fine, 200 with Rarex BG Medium, 400 with Rarex BG Regular (most commonly used for all general radiography procedures), 800 with Rarex BG III. Wolf Film is appropriate for all radiographic procedures and is available in the seven sizes shown in the table below. All Wolf film may be processed manually or automatically and is packaged 100 per box. -------------------------------------------------- Note added at 2 hrs (2008-01-04 14:03:28 GMT) -------------------------------------------------- Kaset, Rafransatör 18x24, 24x30, 30x40,35x35,35x43, 15x30 panoramik film kaset ve rafransatörlerinde (yeşil-mavi 100-200-400 hız) ithalat fiyatları.

These screens are intended for use with orthochromatic or green sensitive X-Ray film. Green screens are available in four speeds: Fast, Regular, Medium, and Fine. GREEN MEDIUM: This green emitting rare earth screen has a relative system speed of 200 when used with a medium speed green sensitive film. This screen/film combination is primarily recommended for specialized studies that require improved resolution compared to a 400 speed system (Regular). GREEN FAST: This green emitting rare earth screen has an approximate relative system speed of 600 when used with a medium speed green sensitive film. When used with a high speed green film system speeds of 1000 to 1200 can be achieved. GREEN REGULAR: This green emitting rare earth screen has a relative system speed of 400 when used with a medium speed green sensitive film and 800 speed with high speed green film. This screen is highly recommended for all general radiographic procedures, providing an optimum balance of dose reduction and image quality. GREEN FINE: This green emitting rare earth screen has a relative system speed of 100 when used with a medium speed green sensitive film. This screen is recommended for general extremity studies. This screen provides an excellent balance of image quality and sensitivity, which cannot be duplicated by the use of non-rare earth, detail screens. The GREEN FINE screen should only be used with film that is orthochromatic or green sensitive. Please note the screen comparison chart in the back of this brochure for screen equivalents. Bule Intensifying Screens Blue Intensifying screens contain high quality calcium tungstate phosphors. Compared to rare earth phosphors this phosphor exhibits a more linear response over a broad kVp range. Blue Screens are available in three speeds (for general diagnostic radiography): High Plus, Medium and Detail. BLUE DETAIL: This blue emitting calcium tungstate screen has a relative system speed of 50 when used with a medium speed (full speed) blue sensitive film. BLUE HIGH PLUS: This blue emitting calcium tungstate screen has a relative system speed of 200 when used with a medium speed (full speed) blue sensitive film. This screen is recommended for general radiography providing an efficient balance of speed and image quality. BLUE MEDIUM: This blue emitting calcium tungstate screen has a relative system speed of 100 when used with a medium speed (full speed) blue sensitive film. This screen is useful for detail studies providing a reduced X-Ray dosage compared to BLUE Detail * These screens are compatible with full or medium speed blue sensitive film. Do not use these screens with green sensitive or half speed blue film. * Please note the screen comparison chart in the back of this catalog for screen equivalents. Half Blue Intensifying Screens HALF BLUE screens are available in three speeds: HALF Blue III, HALF Blue Fast Detail, HALF Blue Detail. HALF BLUE: The active X-Ray phosphor component of FRH screens is comprised of lanthanum oxybromide. This X-Ray phosphor emits light in the blue and ultra violet portions of the light spectrum. The construction of these screens is specially designed to maximize useful life and minimize damage due to moisture and other common contaminants that may come in contact with the screen surface. HALF BLUE-III: This blue emitting rare earth screen has a relative system speed of 800 when used with full or medium speed blue sensitive film. This combination is generally recommended for conditions where dosage reduction and "penetration" is of primary importance (e.g. lateral lumbar studies). When used with a half speed blue sensitive film the relative system speed is 400. This combination is recommended for general radiography. HALF BLUE-FAST DETAIL: This blue emitting rare earth screen has a relative system speed of 400 when used with full or medium speed blue sensitive film. When used with a half speed blue film this screen has a relative system speed of 200. This versatile product can be used in both general radiography and in applications requiring high radiographic detail. HALF BLUE-DETAIL: This blue emitting rare earth screen has a relative speed of 100 when used with full or medium speed blue sensitive film. When used with a half speed blue film the system speed is approximately 50. This product is mainly recommended for extremity studies. * These screens are compatible with full or half speed blue film. Do not use these screens with green sensitive film. * Please note the screen comparison chart in the back of this brochure for screen equivalents. |
