Final answer:
The ASRT document that defines the radiographer's role is the Practice Standards, explaining professional conduct and imaging techniques like lateral, PA, axial, and oblique projections.
Step-by-step explanation:
The ASRT document that defines the radiographer's role is the Practice Standards. These standards are a crucial framework that ensures radiographers maintain a professional level of practice and adhere to established protocols. They include various types of radiographic projections, such as lateral projection, PA (posteroanterior) projection, axial projection, and oblique projection, which are different techniques used to capture images of the body from various angles and positions for diagnostic purposes.
Unlike the options a) Standards of Ethics, c) Standard of Care, and d) Legal Standards, which also guide the radiographic profession, the Practice Standards specifically detail the expectations for professional conduct, clinical performance, quality of care, and the roles of the radiographer in various imaging procedures.
