Relation between body mass index and position of chest examination as a function of entrance surface dose

Abstract

Abstract X-ray is ionic radiation which is now a necessity in the health sector as a tool in establishing diagnosis. Calculation of exposure doses in patients generally only considers gender and age, but from a theoretical point of view, energy absorption will be greater with increasing thickness of material. The thickness of the material in terms of chest examination using X-rays is indicated by position of the examination where the lateral examination makes the material exposed to radiation thicker than the posterioranterior or anteriorposterior examination position, as well as the patient's body mass index. Therefore, the relationship between the position of examination and body mass index to the entrance surface dose is the topic of this study. Analysis of chest examination data in several patients with various examination positions and different body mass indices showed an increase in entrance surface dose with increasing body mass index and examination position. The highest entrance surface dose was observed in patients with lateral examination positions, as well as in patients with large body mass indexes.
