Explain the importance of reducing exposure dose and time to a patient undergoing a diagnostic X-ray examination. Describe ways to achieve this.

X-ray Spectra and Medical Uses of X-rays

There are two distinct components to an X-ray spectrum generated by an Xray tube — the braking radiation and characteristic lines. The appearances of these two components depend on the nature of the tube and its operating conditions. Describe the features of these components relating them to the mechanisms by which they are produced.

Draw and label a schematic diagram to show the structure of a basic X-ray tube.

Describe the production of X-rays by a rotating anode tube. Explain the advantages of using a rotating anode compared to a fixed anode.
