x-ray film cassette
A cassette is a hard holder that is used to hold the screen and the film. It is a light tight device that cannot enter the light in it. The main purpose of the cassette is to protect the film from exposure to light and protect the film from any Also type of banding or rubbing, avoid scratches.structure
The cassette has 2 parts, the front or front part and the back part. The front part is towards the x ray tube and is made of material of low / low atomic number so that x rays easily expose the x ray film passing through that part. And the back part of the cassette is made of material with high atomic number, usually the lead (pb) is chosen for this. Which acts to absorb radiation and provides protection to the patient from scattered radiation.
The front part of the cassette has a front intensifying screen and the back part has a back intensifying screen. xray film is loaded between the front intensifying screen and the back intensifying screen. The loading and unloading of the film in the cassette must be done inside the dark room.Note-:
The back part of the cassette has clips and hinges which make the cassette anti-light and sometimes these clips cause an X-ray back scatter to bring an art effect to the films but such a high Kelovoltage occurs in radiography.
Never, cassette should be opened in white light and day light as it spoils the x-ray film.
2. During the work in the radiology department, rough handling of the cassette should not be done so that there is no possibility of any scratch or other malfunction in the cassette.
3. The hinge and clip on the backside of the cassette should be checked periodically, if these clips have deteriorated, they should be repaired at the right time or there is a possibility of light and radiation reaching inside the cassette so that the films The
cassette should be kept away from the developer and fixer solution while working in the dark room, otherwise these solution spots may fall on the
cassette 5. The cassette should be periodically cleaned by a cotton pad to prevent dust. Etc. The particles cannot reach inside the cassette. 6. Cassette
should be kept length-wise as per their size, such as books are kept in the cupboard. If the cassette is kept one on top, then pressure comes on the films, which is static on the film. There is a possibility of artifact
7. When the cassette is open during work in the dark room, then the radiographer working in the dark room should speak at least and in case of sneezing, the cassette should be closed immediately, otherwise the saliva emanating from the mouth Drops can cause spots on the screen present in the cassettes, which can also cause artifacts on films.
8. Sterilization / disinfection of cassettes should be done from time to time as it keeps in contact with the patient with very serious and infected diseases.
The back part of the cassette has clips and hinges which make the cassette anti-light and sometimes these clips cause an X-ray back scatter to bring an art effect to the films but such a high Kelovoltage occurs in radiography.
Care / handling of cassette -:
The cassette is a very important device in the radiology department as it provides an anti-light and radiation environment to the film, so that to a large extent the quality of the image in the radiology department can be avoided, so the cassettes need some special precautions. Which is as follows 1.Never, cassette should be opened in white light and day light as it spoils the x-ray film.
2. During the work in the radiology department, rough handling of the cassette should not be done so that there is no possibility of any scratch or other malfunction in the cassette.
