Abstract

This study was conducted to ultimately reduce unnecessary radiation exposure by emphasizing the need and importance of correct positioning by examining the positioning relationship of anatomical structures in the human body and changes in X-ray images according to changes in patient positioning during the left lateral chest X-ray examination. This study investigated and analyzed previously published papers and books on the left lateral chest X-ray examination to find out the importance of positioning in the left lateral chest X-ray examination. To find out the importance of correct positioning in the left lateral chest X-ray, we compared three images of incorrectly positioned right thorax and left thorax rotated forward and the lower median surface of the body leaning against the image receptor. In the left lateral chest examination, a distorted image was obtained in which the shape of the anatomical structure observed in the image was changed according to the presence or absence of rotation of the patient and the inclination of the median visual surface. X-ray images with the most accurate and large amount of information were obtained from X-ray images with the correct positioning performed during left lateral chest X-ray examination. Therefore, It is believed that the left lateral chest X-ray examination will have beneficial effects such as providing accurate medical information, preventing misdiagnosis, reducing social costs, and ultimately reducing radiation exposure.
