Radiography 101 is written and medically reviewed by Paul Zeta, RRT, MBA, a practicing imaging professional — a registered radiologic technologist (RRT) and clinical radiography instructor.
The site is authored by Paul Zeta, RRT, MBA, a registered radiologic technologist with hands-on clinical experience in general radiography and a professional background as a radiography instructor. The author worked as a clinical staff radiographer in a hospital imaging department and taught radiologic technology, which directly informs the examination preparation and positioning content published here.
Positioning and physics guidance can affect patient care and examination outcomes, so every article is written and reviewed by someone with actual clinical and teaching credentials in the field — not by an anonymous copywriter. Content is checked against established radiography references (including Clark's and Merrill's), official ARRT / CAMRT / PRC–RTLE materials, and peer-reviewed professional guidance, as detailed in our editorial policy.
Questions about the content, corrections, or our review process are welcome — reach out at contact@radiography101.org.
Radiography 101 is an independent educational resource. It is not affiliated with, endorsed by, or reviewed by the ARRT, CAMRT, PRC, or any examination board. Vendor and examination-board references are cited for factual accuracy only.
