Analysis of Patient Radiation Dose and Quality of Radiograph for Adult Thorax Diagnosis Use High Kilo Volt Method

Abstract

Quality of radiographic images of thorax is influenced by radiation quality. Hence research is needed related to the effect of high kV method for adult thorax diagnosis. The effect of the radiation quality on the image can be known through the density of the film resulted from the stepping of the stepwedge object. The effect of high kV use on doses was done by analyzing incident air kerma on two radiography planes with Philips and Toshiba brands. From this study it was found that using of high kV method will caused image contrast to decrease when compared with standard kV method (generally used). But the image of the lung bronchus will be seen more than the use of standard kV method. In the use of high kV method can be done with a low burden tube (mAs), Thorax consists of lung organs and heart. It is moves or hard to resist so it is suitable for use because it takes a short time. The use of high kV method decreases the patient's acceptable dose by still producing an optimal diagnosis of adult radiographs.
