This is the principle of justification; Once justified, the examination should be performed with minimal radiation dose. This requires achieving adequate image quality while keeping the exposure as ...

Nevertheless, it is important that exposure times are adjusted to give only enough radiation to obtain a diagnostic image. Overexposure of a digital detector is unlikely to result in an ...

Anything that increases the amount of radiation exposure e.g. longer fluoroscopy times, more radiograph images generated, proximity to the radiation source, positioning the X-ray source above the ...
