RADIOGRAPHIC BUCKY

History:
The
concept of using radiographic bucky dates back to the early days of X-ray
imaging. Prior to the development of bucky devices, images were obtained by
placing the patient on a table and holding the film behind the body part being
imaged. This method resulted in poor image quality due to scattering radiation
from the patient's body. In 1913, Dr. Gustave Bucky developed the first grid,
which was a stationary grid mounted directly behind the image receptor. Later,
a movable grid was developed, allowing the grid to move in synchrony with the
image receptor. This was the first step toward the modern bucky design.
Design:
Modern
radiographic buckys are typically designed as a tray that holds the image
receptor, which can be moved in and out of the tray during imaging. The bucky
contains a grid of thin lead strips that are oriented perpendicular to the
X-ray beam. The grid absorbs scattered radiation while allowing the primary
X-ray beam to pass through and expose the image receptor. The image receptor is
held securely in place within the bucky, reducing motion artefacts in the
resulting image.
Use:
A
radiographic bucky is typically used in conjunction with a radiographic table
or stand. The patient is positioned on the table or stand, and the bucky is
positioned over the body part to be imaged. The X-ray tube is then aligned to
project the beam through the bucky and onto the image receptor.
The use of bucky results in improved image quality by reducing scatter radiation that can degrade the image contrast. It also allows for more consistent image production by holding the image receptor securely in place and reducing the potential for motion artefacts.
Overall, the use of a radiographic bucky has been a significant advancement in X-ray imaging technology, improving image quality and consistency while reducing patient radiation exposure.
