Question

describe the relationship between measured exposure and exposure index( radiology question) *please explain in it in word not equation!

Answer 1

Exposure index in radiography is defined as the relative index of speed and sensitivity of digital receptor to the incident X-Rays and this is used to provide appropriate feed backs. Exposure on other hand is referred as concentration in air and radiation at a specific point. Exposure index is the measure of the single level of radiation produced by a detector during the exposure.

As defined exposure index does not indicate the dose of radiation to the patient but it helps in understanding the index of radiation that will be extracted during one linear exposure at a point. The exposure measures is dependent on exposure index as it will be equal to the index justified by the manufacturer.
