Measurement of radiation dose for patients by CT scan and x-rays

Abstract

When the patients examined by x-rays and CT, it is found that the examination by x-rays are the most common and widely available diagnostic imaging technique. The images are read quickly, because the time required for the images to be finished in about 10 minutes. The result shows that; there is a positive relationship between time exposure and voltage. CT scan costs more and takes more time than x-ray and it is not always available in small hospitals and rural areas. Also, it is found CT scan is more accurate to get image for any parts of the body, one of the most accurate tools for examining the chest, abdomen and pelvis because it provides detailed, cross-sectional views of all types of tissue, Also used to examine patients with injuries from trauma such as a motor vehicle accident, performed on patients with acute symptoms such as chest or abdominal pain or difficulty breathing. The result shows that; there is a positive relationship between weight and radiation dose.
