Radiographic Positioning and Procedures Handbook: Systematic Approach to Patient Setup, Central Ray Alignment, & Evaluation Criteria for Radiologic Te
Built for radiologic technology students and the technologists who supervise them in clinic, this reference connects the anatomy of surface landmarks and joint geometry to the central ray decisions that separate a diagnostic image from a repeat exposure. It moves from positioning terminology, body planes, and evaluation-criteria fundamentals through every major projection of the appendicular and axial skeleton, then into cranial, facial, and trauma-adapted technique, pediatric and geriatric/bariatric positioning adjustments, mobile and surgical C-arm imaging, and contrast-assisted fluoroscopic studies. Central ray angle, source-to-image distance, and the specific anatomical relationships each evaluation criterion confirms are worked out at every projection, not asserted.
The Central Ray Compass - Landmark Bearing, CR Heading, IR and SID Placement, Positioning Trap, Compass Lock - repeats at every major projection and consolidates into an indexed back-of-book Atlas built for quick clinical lookup.
From the Landmark to the Image, You Will Learn How To
- Lock central ray geometry - landmark-to-CR-angle reasoning that replaces guesswork with a repeatable bearing.
- Position the full appendicular and axial skeleton - hand through pelvis, cervical through sacrum, with the evaluation criteria that confirm each projection succeeded.
- Adapt cranial and facial technique for trauma - Waters, Caldwell, and Towne method variations, orbital and Le Fort fracture imaging nuance.
- Reposition safely across the lifespan - pediatric immobilization and distraction technique, geriatric fall-risk precautions, bariatric equipment and exposure adjustment.
- Run the mobile unit and the C-arm - sterile field discipline, portable trauma sequencing, and intraoperative fluoroscopic views by specialty.
- Support contrast-assisted studies - upper GI series, barium enema, and voiding cystourethrogram positioning alongside the fluoroscopic team.
- Catch the trap before the repeat - the recurring positioning errors named at every projection and cross-referenced in the Atlas.
- Build career-long quality assurance habits - repeat and reject analysis, image-quality self-review, and professional practice standards.
Bring positioning technique you can defend into every exam room you enter.
