Question

Which of the following components supply electical power to the x-ray tube?

1. x-ray generator
2. kVp meter
3. X-ray transformer
4. mA meter

Answer 1

The electrical power to the X-ray tube is supplied by the high-voltage generator and the mA meter.

Step-by-step explanation:

The electrical power to the X-ray tube is supplied by two main components: the high-voltage generator and the mA meter. The high-voltage generator is responsible for accelerating the electrons towards the target in the tube by providing a high potential difference. This potential difference is typically measured in kilovolts (kV). The mA meter, on the other hand, controls the intensity of the electron beam by regulating the current flowing through the tube. This current is typically measured in milliamperes (mA).

For example, if an X-ray tube has an accelerating voltage of 1.00 × 10² kV and a current of 15.0 mA, the power of the electron beam can be calculated using the formula:

Power = Voltage × Current

So in this case, the power would be:

Power = 1.00 × 10² kV × 15.0 mA = 150 kVA × 0.015 A = 2.25 kVA
