RADIOGRAPHIC & MAMOGRAPHIC EQUIPMENT

An magnetic resonance imaging machine is one of the most popular radiology equipment

• The x-ray machine is divided into four major components.

• The Tube• The Operating Console• The High Voltage Section• The Film Holder , Grid Cabinet or Table

• Floor mounted x-ray tube stand.• Wall grid cabinet or Bucky• Mobile Table with grid cabinet (optional)

• The Bucky-Potter grid is a device invented by German radiologist Gustav Bucky and improved by American radiologist Hollis E. Potter that enhances the quality of diagnosticmedical x-ray images. The grid is positioned on the opposite side of the patient from the x-ray tube to reduce the quantity of scattered x-rays that reach the film, fluorescent screen, or x-ray image intensifier. Reducing the amount of scattered x-rays increases the image’s contrast resolution and, consequently, the visibility of soft tissues.

• Control Booth should contain the operator console and technique charts and space to store cassettes.

• The wall between the booth and X-ray unit is shielded.

• High Voltage Section or Generator used to change incoming power to levels needed to produce x-rays.

The X-Ray Tube Development

• Dr. Roentgen used a Crookes-Hittorf tube to make the first x-ray image.

• There was no shielding so x-rays were emitted in all directions.

The X-Ray Tube Development

• The Coolidge Hot cathode tube was a major advancement in tube Design. The radiator at the end of the anode cool the anode.

The X-Ray Tube Development

• This is a modern rotating anode x-ray tube. It is encased completely in a metal protective housing.
