Generator and X-ray tube<br />
The anode rotates rapidly (3,500 –<br />
10,000 rpm) to help dissipate the<br />
tremendous heat generated.<br />
X-ray tube surrounded by circulat<strong>in</strong>g oil<br />
The whole system is remarkably<br />
<strong>in</strong>efficient<br />
i Anode is tungsten - converts the<br />
electrons <strong>in</strong>to X-rays.- steeply angulated<br />
(8 –15°) - X-rays <strong>com</strong>e from as much a<br />
po<strong>in</strong>t source<br />
S<strong>in</strong>ce low-frequency X-rays contribute<br />
to radiation exposure but not image<br />
quality- alum<strong>in</strong>um or copper filters<br />
The beam is also shaped by the use of<br />
collimators at this po<strong>in</strong>t to help focus<br />
the eventual direction the X-rays travel.<br />
