Measurement of patient dose in cardiac scintigraphy

Abstract

In this study were calculated radiation dose to diagnose heart disease by using a Gamma camera and the process of photography in two phases filming under the influence of voltage and imaging at rest, and survey was conducted for 25 patients by injecting the patient elementTc-99m being done by ECG continued during examination voltage or when give some medicine hearty alternative to exercise that increase heart rate and during which inject the patient a radioactive elements then taken image of the heart muscle directing gamma camera to capture the radioactive material, which inhabited the cells of the heart muscle (Picture stress) while taken second image in the same way to take the first picture after two to four hours (at rest). We found that the weights vary between patients (70-140) and was in the test dose of rest between (3.75-5.56) As in the case of voltage between (3.33-6.33), depending on the weights of patients and the average doses in the case of the two tests together (0.98 ± 4.47) and the average equal weight (14.67 ± 95.44) and results demonstrated that the dose in the big weights are high with a different type of scan.
