| When a patient is instructed to lay supine on the radiographic table for a Bucky exam, what is the very first step to positioning the patient? | Align the long axis of the patient with the long axis of the table/IR. |
| Describe general guidelines for correct marker placement. | - Place on lateral side of collimation for tabletop exams. - Place at narrowest part of the anatomy. (Why?) - For Bucky exams, place about 1" from edges of IR. |
| What is the difference between the terms POSITION and PROJECTION? | POSITION = the actual position of the patient's body. PROJECTION = the path of the CR |
