How to center the x-ray tube for Bucky detent

In my last video, I showed you how to center for a table top exam (aka small extremities) When we radiate a body part that is more than 10 cm in thickness (current 2025 ARRT numbers), we should switch to a bucky (either table or wall) because of the addition of a grid to help clean up scatter. Remember, more matter, more scatter!!! Don't forget the 3 locks for detent: 1. SID 2. Trans detent 3. Longitudinal detent #radiologyschool #fyp #xrayschool #detent #xray
