If you pour a 1.5% acetic acid solution into the basin, in which you rinse the image, the development of the photo will stop.įixation is the destruction of unreduced silver from the composition of the emulsion layer of the image. Better yet, rinse the film in a slightly acidified liquid. In the room where the treatment takes place, it is necessary to have a washbasin with a tap and water. The developed film is thoroughly washed in normal cold water. In 1 liter of such a developer, 1m 2 of starting material can be developed. They develop the same photo in 20% less time. More modern domestic developing reagents TRM-110R and Renmed-V appeared on sale. The temperature should not differ from the optimum in any direction by more than 4 degrees. If the temperature is reduced by 1 degree, the image development period is increased by 10%. If the temperature is increased by 1 degree, you need to reduce the photo development time by 10%. Films produced in the Fatherland have a marking, where it is written how long it is necessary to develop the film in the specified developer at a given temperature regime (20 g.). The developer for X-ray film Roentgen-2 is popular among radiologists. If developing manually, you must first take care of the optimal processing conditions for the image. All the necessary conditions are set automatically in the X-ray film developing machine. The photo exposure parameters depend on the screen parameters, on the X-ray film parameters, on the development conditions, on the developing and fixing reagents. After use, the screens are wiped with a cotton swab soaked in a solution specially developed for this purpose. Manufacturers take care that the screens do not have mechanical damage. They are accompanied by sets of screens for amplification. Exposure processĭomestic classic films are sold in cassettes to maintain opacity. Agfa recommends buying developer and fixative from the same company when using Agfa D5 blue-sensitive film. The manufacturer claims that the image is stable when the conditions of development change, clarity when developing with weaker developers. She details the photo to the smallest nuances. It is successfully used in radiography of the lungs, bone structure, and in angiography. In Russian radiology, Agfa blue-sensitive film is popular, especially Agfa D5. The following table shows the types of imported films and their parameters: Country It is impossible to develop them qualitatively by hand. On the other hand, imported films available on the market are only suitable for developing machines. It is suitable for processing machines and for manual development. In recent years, Russia has been producing RM-D film based on imported raw materials. These films are not suitable for automatic development in a developing machine. For fluorography, a domestic product RF-3 is produced. These are blue-sensitive films RM-1 and RM-K. Domestic and foreign productsĭomestic films have been produced for a long time, and are mainly intended for manual development. Medium gradient indicates the contrast setting of the film. Sensitivity is the reciprocal of the amount of x-rays required to take x-rays. In fluorographic examination, the green range of the spectrum is used. There are films that contain dyes that also make them sensitive to red light.īlue light is used in the classic use of radiography, in the production of conventional X-rays. When dyes are added to the emulsion layer, the film is also receptive to the green range of the spectrum. They are sensitive to the blue range of the spectrum. There are films containing silver halides without dye impurities in the photosensitive layer. The sensitivity index is determined regardless of the type. Fluorographic film is available in rolls. For this, an optical system has been designed. They are used to take pictures at a reduced size. This type of film is used for taking pictures at a scale of 1: 1.įluorographic type of film has an emulsion layer on one side. It is used in conjunction with 2 amplification screens. These layers form a light-sensitive surface, that is, such a film is double-sided. There are also X-ray plates for specific purposes, but they are rarely used in medical practice.įilms of classic use are sheets of various sizes (most often 40x40 cm), on which layers of emulsion are applied on both sides. If we consider the types of medical X-ray film, then it is divided into radiographic, used for general radiology, and fluorographic.
