How can excessive radiation dose be avoided in DXR?

The prevention of excessive radiation dose in DXR (Digital X-ray Radiography) is best achieved by optimizing exposure settings and using appropriate shielding. This approach involves carefully adjusting the technical parameters of the imaging equipment, such as the exposure time, current, and voltage, to ensure that the lowest possible radiation dose is used while still obtaining high-quality diagnostic images.

Optimal exposure settings allow for sufficient image quality without unnecessary exposure to radiation. For instance, if the equipment settings are too high, the patient will receive more radiation than necessary. Additionally, implementing appropriate shielding—such as lead aprons or barriers—further reduces the amount of radiation that reaches the patient and staff, contributing to overall safety.

Using low-density materials, increasing distance from the radiation source, and limiting patient access can be beneficial in certain contexts but do not directly address the fundamental need to balance image quality with radiation safety. Proper optimization and shielding are critical in clinical practice to minimize radiation exposure without compromising diagnostic effectiveness.
