The process by which a beam of radiation is reduced in intensity when passing through matter. It is the combination of absorption and scattering processes and leads to a decrease in flux density of the beam when projected through matter.
Industry:Medical devices
To reduce the strength of an X-ray or electron beam. Filters and foils diminish their respective X-ray and electron beams by directing the beam through a metal disk that is thicker in the center than at the edges; this action attenuates the center of the beam more than the edges, and thus "flattens" or equalizes the area of the beam.

Anterior/Posterior. It denotes the path the beam takes through the body. AP means the anterior surface of the patient‘s body is entered first and it exits posteriorly, through the back.
Industry:Medical devices
A sequence of well-defined, unambiguous rules or processes for the solution of a problem in a finite number of steps. Computers can carry out the steps in many kinds of algorithms.
Industry:Medical devices
Fans, or air intakes with filters, that move air inside the Stand and gantry, and exhaust them through the top or upper back of the Stand.
Industry:Medical devices
The opposite of vacuum. A major part of beam generation takes place in a vacuum, which is maintained by the vacion pumps. If a pump fails, or some breach occurs, the system is said to “go down to air. ” A portion of beam generation takes place in air, after the beam leaves the bend magnet, before it strikes the target, and then strikes the ion chamber.
