Which radiography practice is least effective in minimizing patient radiation exposure?

Increasing the number of X-ray views is least effective in minimizing patient radiation exposure because it inherently requires additional imaging, which translates to more radiation being directed at the patient. Each additional view adds cumulative radiation dose, even if each view may be necessary for a thorough assessment.

In contrast, using high kilovoltage usually allows for better penetration through tissues, which can reduce the amount of radiation needed to obtain adequate images. Utilizing filtration also helps remove lower-energy X-rays, which contribute little to diagnostic quality but increase patient exposure. Proper collimation serves to limit the X-ray beam to only the area of interest, reducing unnecessary radiation to surrounding tissues. Each of these techniques plays a critical role in managing patient exposure effectively, while increasing the number of views does not minimize exposure but rather increases it.
