How is magnetic flux density applied to radiography?
Important in field strength in MRI
How is power (Watts) applied to radiography?
Output of x-ray detector
How is electric charge applied to radiography?
Quantity of electrons flowing per second
What is the intensity of the x-ray beam multiplied by?
mA multiplied by the kV multiplied by the length of exposure
What is the mAs dependent on?
The number of x-rays
What is forced measured in?
Newtons
For work to be done:
Force must be in the direction of movement and there must be movement
What is potential energy?
Stored energy, waiting to released by conversion into a different energy form
