Abstract

There is general agreement that the extent of the risk from x-ray examination is related in some way to the radiation dose. As the dose increases, the likelihood of significant biological effects also increases. If a clear correlation between dose and effect is to be established, a convenient and reasonably accurate method of estimating patient’s absorbed doses during common radiographic examinations will be highly needed. A simple method is developed in this project to determine the two important parameters e exposure at skin entrance (ESE) and half value layer (IIVL), which is essential to get reasonably accurate estimates of absorbed doses. Then, the patient’s absorbed doses in common x-ray examinations can be estimated using the computer program. The absorbed doses in 12 routine radiographic projections were calculated by the use of clinical data in MCV Hospital.
