Final answer:
The set of technical factors that would most likely produce the least patient exposure is: 68 kVp, 100mA, 0.06 seconds.
Step-by-step explanation:
The set of technical factors that would most likely produce the least patient exposure is: 68 kVp, 100mA, 0.06 seconds.
Reducing the kilovoltage peak (kVp) decreases the energy of the X-rays produced, resulting in less penetration and lower patient exposure. Lowering the milliamperage (mA) reduces the number of X-rays generated, further decreasing patient exposure. Lastly, decreasing the exposure time reduces the overall duration of radiation exposure.
