anode,

the electrode at which oxidation occurs. anodal, adj.

anode (an´ōd),

n the electrically positive terminal of a roentgen ray (radiographic) tube; a tungsten block embedded in a copper stem and set at an angle of 20° or 45° to the cathode. The anode emits roentgen rays (radiographs) from the point of impact of the electronic stream from the cathode.

anode, rotating,

n an anode that rotates during radiograph production to present a constantly different focal spot to the electron stream and to permit use of small focal spots or higher tube voltages without overheating the tube.

anode

the positive electrode or pole to which negative ions are attracted.

The stationary anode in an x-ray tube is a solid bar of copper with an inset of tungsten on the face of the bar opposite the cathode filament. The tungsten target has a high melting point to withstand the intense heat of the x-ray beam—the copper conducts the heat away.

anode-film distance

see focal-film distance.

rotating anode

an x-ray tube in which the anode rotates when x-rays are being produced. This means that there is a larger effective target surface of the anode which can be available to generate x-rays.

stationary anode

a non-rotating anode in an x-ray tube so that the target surface is comparatively small.
