The purpose of this study is to determine if there is a significant difference in dose received by radiosensitive organs/tissues when exposures are taken in an anteroposterior (AP) or posteroanterior (PA) position for a scoliosis series. To conduct this research, a thorax phantom and dosimeter were utilized to measure the absorbed radiation dose to the patient when they were positioned in an AP versus PA position. The results of the experiment found that the radiation dose absorbed by the radiosensitive organs was 2248% less when the projection was taken in a PA position than an AP position. Additional experiments conducted by researchers have found similar results.
