The image quality factor is not merely a matter of whether the image is repeated or not, but also has a wide range of information and also has to maintain the protection method for the patient is the reception of the dose due to radiographic action. So it is necessary to monitor the patient's dose using the EI value. The factors that determine the EI value are the exposure factor and the thickness of the object or BMI (Body Mass Index). Exposure factors (kV and mAs) are factors that have been commonly used as patient dose monitoring, where the tube voltage is a component that changes more often with a relatively constant tube current. The study used data on patients with Thoracic examination at the age of 20-65 years which were then categorized into BMI. The analysis was carried out on the EI value contained in the radiographic image. The results showed that BMI in the normal, Light Grade Fat (LGF), Heavy Grade Fat (HGF) categories, respectively, the EI values were 1562, 1679, and 1955 for the female sex, and 1266, 1600, and 1821 for the male gender. Significantly (P?0.05) the EI value showed difference between female and male sexes.
