What is the X-ray cassette?
An X-ray cassette is a light-resistant container that protects the film from exposure to daylight, holds the film between two intensifying screens and allows the passage of X-rays through the front cover on to the film.
How do you explain what an X-ray is to a child?
X-rays are special pictures of the inside of your body. A doctor will decide when you need an X-ray and what body part needs to be X-rayed. An X-ray machine, not a camera, is used to take these pictures.
How many types of X-ray tape are there?
The formats of the cassettes used in conventional radiology are: 13 x 18 cm; 18 x 24 cm; 24 x 30 cm; 20 x 40 cm; 30 x 40 cm; 35 x 35 cm; 35 x 43 cm; 30 x 90 cm. No cassette is used in digital radiography.
What is an X-ray simple definition?
X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. The most familiar use of x-rays is checking for fractures (broken bones), but x-rays are also used in other ways.
What is the purpose of cassette?
Cassette, also called tape cassette, in audio and video recording, flat, rectangular container made of plastic or lightweight metal that holds magnetic tape for audio or video recording and replay.
What is the importance of cassette in radiology?
The Role of X-ray Cassettes in Radiographic Procedure For the technologists, the cassette ensures that the highest-quality image will not be compromised by outside light. Furthermore, it protects the image from physical damage created by dust, dirt, and other external contaminants.
What are the types of intensifying screen?
An intensifying screen is a plastic sheet coated with fluorescent material called phosphors. Phosphors are materials which convert photon energy to light. LUMINESCENCE is the emission of light from a substance bombarded by radiation. There are two types; fluorescence and phosphorescence.
How does a cassette work?
How does cassette tape work? Cassette tape is coated with magnetic particles, either iron oxide or chromium oxide. Each magnetic head realigns the magnetic particles on the passing tape in patterns that correspond to the loudness and frequency (rate of vibration) of the incoming sounds.
What is the function of cassette?
Cassettes are used in association with intensifying screens and have related FUNCTIONS: 1. To contain a film 2. to exclude light, 3. to maintain the film in close, uniform contact with both screens during the exposure, 4. to protect the intensifying screens from physical damage.
What is the importance of intensifying screen?
Intensifying screens are used in the x-ray cassette to intensify the effect of the x-ray photon by producing a larger number of light photons. It decreases the mAs required to produce a particular density and hence decreases the patient dose significantly.
What is importance of intensifying screen?
What are the functions of a radiographic film cassette?
Introduction A radiographic film cassette is a rectangle or square plastic or metallic container used to hold x-ray films (exposed or unexposed) and intensifying screens in close and uniform contact with one another.4-4-2011 RADIOGRAPHIC CASSETTES BY SUDIL 2. 3. Functions1.
What kind of screen is on a cassette?
A radiographic cassette contains one or two intensifying screens and a sheet of x-ray film. 2. A perforated holder in which tissue blocks are placed for paraffin embedding.
What does grid cassette mean in medical terms?
a light-proof housing for x-ray film and electrostatic imaging plates, containing front and back intensifying screens, between which the film is placed; a magazine for film or magnetic tape. grid cassette a cassette that has its front replaced by a built-in grid.
What is the origin of the word cassette?
Etymology: Fr, little box. a device used in radiography for holding a sheet of x-ray film and one or two screens. A cassette also may have a grid to absorb scattered radiation.
