Which factor is known to reduce patient dose effectively?

Reducing the mA (milliamperage) is known to effectively reduce patient dose because it directly influences the amount of radiation exposure during imaging procedures. The mA setting affects the quantity of X-ray photons produced; therefore, lowering the mA decreases the overall radiation emitted during the examination. This adjustment allows for sufficient image quality while minimizing the exposure to radiation, which is critical in safeguarding patient health.

Additionally, while maintaining image quality is essential, the reduction of mA needs to be balanced with other factors such as exposure time and patient positioning. The goal is to achieve optimal imaging with the least amount of radiation possible, protecting patients from unnecessary exposure while ensuring diagnostic efficacy.
