Question

Which of the following has the highest patient dose assuming all other parameters are the same?

1) mA=200, rotation time=2 seconds
2) mA=200, rotation time=1 second
3) mA=150, rotation time=3 seconds
4) mA=400, rotation time=1 second

Answer 1

In this question, option 3) with a product of 450 has the highest patient dose assuming all other parameters are the same.

Step-by-step explanation:

In this question, the patient dose depends on the product of the milliamperage (mA) and the rotation time. The higher the product, the higher the patient dose. Let's calculate the product of mA and rotation time for each option:

1. mA = 200, rotation time = 2 seconds, product = 200 * 2 = 400
2. mA = 200, rotation time = 1 second, product = 200 * 1 = 200
3. mA = 150, rotation time = 3 seconds, product = 150 * 3 = 450
4. mA = 400, rotation time = 1 second, product = 400 * 1 = 400

From the calculations, option 3) with a product of 450 has the highest patient dose assuming all other parameters are the same.
