Abstract

The absorption coefficient of contrast media was measured in region of diagnostic radiology. Relative values of absorption coefficient was found the largest peak in the range of $60{\sim}70\;kVp$ for barium sulfate and 60 kVp for iodine. Increasing the thickness of contrast media and patient, the values of absorption coefficient was rising. In the Radiograph, desired $70{\sim}80\;kVp$ in the gastrointestinal digestion tract with barium sulfate and the vascular tract is before and behind 65 kVp of exposure.
