Abstract

Two x-ray exposures are normally done to detect the position of an artifact in space. This is achieved by either moving the X-ray tube or the patient to obtain a 90-degree view from the previous one. In the movement of the patient, the position of the artifact is moved from the anterior posterior (AP) to the lateral (Lat) position [1]. This technique results in dose to the patient. A method to detect the position in space with only one X-ray exposure was developed to limit the amount of radiation for detection of an artifact. This article discusses this technique as well as methods to improve image quality in terms of position detection is space [ 2-7].
