POTTER-BUCKY DIAPHRAGM

Typical Number in Hospital: Cost Bands: References: 7

More commonly known as a 'Bucky', this is an assembly which is normally located under the table of a diagnostic X-ray set and holds the X-ray film cassette and the secondary radiation grid. The grid is used to prevent secondary X-ray emission from the patient from reaching the X-ray film, and is formed from a large number of thin strips of lead separated by a radiolucent material. To prevent the outline of the grid from appearing on the film a mechanism is provided for moving the grid during exposure. The Bucky is mounted on bearings which permit movement along rails under the X-ray table so that the grid and film can be moved to an appropriate position under the patient. The Bucky is used with most diagnostic X-ray equipment.

Vertical, pedestal, and cantilever types exist which can be used with mobile X-ray sets. For ward and theatre work, stationary grids are sometimes used with ordinary cassettes, or the grid is within the cassette.
