Images were assessed against an image quality criteria Likert scale by qualified radiographers. The phantom was repositioned PA erect and repeated. Materials and methods: An anthropomorphic phantom was positioned AP erect against a digital radiography (DR) detector with 30 thermoluminescent dosimeters (TLDs) inserted to record the thyroid, breast, ovaries, and testes absorbed radiation dose at an exposure of 66 kV and 8 mAs. The hypothesis of this study is to evaluate the change in radiation dose and image quality between AP and PA positions. If a posterior-anterior (PA) projection was utilised, the radiation dose could potentially be reduced. Multiple radiosensitive organs lie anteriorly within this anatomical region, increasing the stochastic risk of cancer. Introduction: Anterior-posterior (AP) cervical spine X-rays are routine examinations to assess degenerative change, persistent pain and traumatic injuries.
