Effect of SID on patient dose

Changing the distance of the X-ray tube to the patient affects the dose applied

to the patient.
For example doubling the distance reduces the dose by a factor of 4. The new

dose can be calculated by a formula:
new mAs = known mAs × ( new distance

/ old distance

)

CAUTION:

The distance of the X-ray tube to the patient cannot be less than

45 cm.
