How many heat units (HU) are generated on a high-frequency (HF) generator with an exposure of 300 mA, 0.12 sec., and 95 kVp?

To determine the number of heat units (HU) generated on a high-frequency (HF) generator during an X-ray exposure, you use the following formula:

Heat Units (HU) = mA × time in seconds × kVp × conversion factor

For HF generators, the conversion factor typically used is 1 for single-phase and 1.4 for three-phase or high-frequency machines. Since HF generators usually fall under the three-phase or high-frequency category, we will use the factor of 1.4 for our calculation.

Given:

• mA = 300

• time = 0.12 seconds

• kVp = 95

Now, substituting these values into the formula:

HU = 300 mA × 0.12 sec × 95 kVp × 1.4

Calculating step by step:

1. 300 mA × 0.12 sec = 36

2. 36 × 95 = 3,420

3. 3,420 × 1.4 = 4,788

However, if we directly consider only the basic calculation without the conversion factor or miscalculated, we come about the need to recognize that instead for specific calculations it yields significant
