What is the function of the Bucky?
A bucky is typically used for table or wall mounted x-ray systems and holds the x-ray cassette and grid. A bucky, is a device found underneath the exam table, a drawer like device that the cassette and grid is slid into before shooting x-ray.
What is a Potter Bucky diaphragm used for?
A Bucky-Potter grid is commonly used for chest radiography.
What is the Bucky diaphragm?
Bucky diaphragm – in radiography, a diaphragm with a moving grid that avoids grid shadows.
What is Bucky factor?
The Bucky factor is the ratio of radiation on the anti-scatter grid to the transmitted radiation. Hence, the Bucky factor reflects the increased radiation dose required from anti-scatter grid use, as any increase in mAs proportionally increases dose. The Bucky factor changes with: change in kVp.
Which part of a radiographic table is called a Bucky?
False Moving grids are Called a Bucky, High Frequency grids that Don’t move are called Stationary grids.
What is XRAY grid?
Grids are placed between the patient and the x-ray film to reduce the scattered radiation reaching the detector (produced mainly by the Compton effect) and thus improve image contrast.
What is XRAY tape?
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. The cassette is placed in a grid holder.
What is XRAY collimator?
In radiology, a collimator is an arrangement of absorbers for limiting a beam of X-rays, gamma rays, or nuclear particles to the dimensions and angular spread required for the specific application.
What is air gap technique?
Air gap technique is a well-known method to reduce the amount of scattered x-ray radiation reaching the detector, thus reducing noise and improving image contrast. 1. It is rather commonly utilized instead of a conventional grid in plain radiography.
What is heel effect in radiology?
Anode heel effect refers to the lower field intensity towards the anode in comparison to the cathode due to lower x-ray emissions from the target material at angles perpendicular to the electron beam.
What is the name of the device that moves the grid during the exposure?

What is cassette in radiography?
Cassettes are rigid holders used in conventional and computed radiography (CR) for the screen film system and imaging plate respectively. The back side of the cassette has rubber or felt for adequate contact between the screen film system or with the imaging plate.
