Mastering the Grid: A Comprehensive Approach to Radiographic Positioning Procedures

| Step | Action | Rationale | | :--- | :--- | :--- | | | Ask patient to remove metal artifacts (necklace, bra) and don a gown. | Prevents superimposition over lung fields. | | 2. Stance | Patient stands facing the IR, chin up. Shoulders rolled forward and down. | Rolls scapulae out of the lung fields. | | 3. Landmark | Palpate the jugular notch. Center IR so that top is 1.5-2 inches above the shoulders. | Ensures full lung apices are included. | | 4. CR | Perpendicular to the IR, directed to T7 (mid-thorax). | Creates a true PA projection without magnification of the heart. | | 5. Respiration | Instruct: “Take a deep breath in… hold it.” | Distends lungs for maximum aeration. | | 6. Outcome | 10 posterior ribs visible above the diaphragm; sharp vascular markings; no rotation (clavicles equidistant from spinous processes). | Diagnostic image. | Radiographic Positioning Procedures A Comprehensive Approach
