Question

To reduce patient exposure during pulsed mode fluorescence, what should be chosen?

1) Lower dose rates
2) Higher dose rates
3) Extended exposure time
4) Shortened exposure time

Answer 1

To reduce patient exposure during pulsed mode fluorescence, shortened exposure time should be chosen. This aligns with the fundamental radiation protection principle of minimizing the duration of exposure to decrease the dose received.

Step-by-step explanation:

To reduce patient exposure during pulsed mode fluorescence, the best choice would be to opt for shortened exposure time. Radiation protection measures emphasize the importance of minimizing the time spent in a radiation environment, as less time equals less exposure. Furthermore, while shielding and increasing the distance from the source of radiation also play key roles in protection, exposure time is the direct variable in question here.

Using isotopes with short half-lives in medical imaging is another method to limit radiation dose, as they decay more quickly, reducing the time during which radiation is emitted. Additionally, in medical diagnostics, advances such as faster films have led to a decrease in necessary exposure time, contributing to a reduction in patient radiation dose.
