Contents of position instructions: 1. suggested technical factors 2. image receptor size and orientation 3. patient and part positioning 4. respiration instructions 5. central ray entrance/exit points and angulation 6. image quality points 7. structures demonstrated • Representative radiographic image which can be enlarged for closer inspection. • Enlargeable photograph of properly positioned human model showing the correctly collimated area of interest with the central ray entry point. • A helpful NOTE tab for every position; save techniques, special terms, or other helpful information. • Search function finds search term in position titles and/or instructions. • My Routines function allows grouping of selected positions into a saved routine. • My Notes function allows saving notes not related to a position. • Developed using the ARRT Content Specifications to include nearly all ARRT entry-level radiographic positions. 1. “OPTIONAL” positions are included which may be ordered in clinical practice. These OPTIONAL positions are judged by the authors and other educational colleagues as handy references, but are not listed on the ARRT Radiography Content. • Instructions referenced to the most recent ASRT Radiography Curriculum and national positioning texts. • Content is written, edited and expanded by two Ph.D. radiography educators, each with extensive authoring experience and more than 30 years of teaching experience. • A convenient guide to positioning the patient and a valuable study aid for radiography students. • A great reference and review tool for technologists and clinical instructors.

Verdict
The clearest difference is review sentiment: Skeletal Anatomy 3D at 73% against iRadTech Lite's 25%. Skeletal Anatomy 3D also leads on update cadence (every 4 months vs every 21 months) and iOS requirement (9.0 vs 12.0). iRadTech Lite's advantage is price (Free vs $2.99) and rating (5.0 vs 4.1). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
