How would you manipulate the stupendous circle from A = B x C to solve for C?   

Change 8% into a decimal

Image #6  Lateral Ankle To make image optimal I will: Increase external rotation of the leg (depress toes) Increase internal rotation of the leg (depress heel) Move the CR more anteriorly Decrease flexion of ankle

Image #4  AP Ankle Positioning: All pertinent anatomy is included CR is not directed to the proper point Critical joint spaces are open Anatomy is aligned to the light field

Image #19 Fuji S-Value: 455 Range: 100-400 (no adjustment needed) Under 100 Over-exposed (- Technique)  Over 400 Under-exposed (+ Technique) To make image optimal I will: Move the CR posterior Increase technique Decrease technique Place lead anatomical marker anterior within light field

Image #9 Positioning: The CR is correctly angled The CR is over-angled The CR is too proximal No rotation is present

Image #18 What projection/position does this represent?

Image #16 Fuji S-Value: 311 Range: 100-400 (no adjustment needed) Under 100 Over-exposed (- Technique)  Over 400 Under-exposed (+ Technique) To make image optimal I will: Extend the mandible (to be optimal and collar was removed/ c-spine cleared) Open collimation to include anatomy of interest Move the CR anterior to proper point Decrease the technique

Image #5  Oblique Ankle (Mortise) Positioning: Anatomy is under-rotated Anatomy is over- rotated Ankle joint is under-dorsiflexed Sufficient collimation is present

Image #20  L5-S1 Spot To make image optimal I will: Move the CR down to proper point Position spine parallel to IR Place lead markers in light field Modify/ use tube angle
