Question

when performing an anteroposterior (ap) upright chest radiograph when the patient is on a stretcher, the technologist must ensure that the angle of the tube matches the angle of the:
○ patient’s chest
○ image receptor (ir)
○ back of the cart
○ no angle is required for an anteroposterior (ap) upright chest on a stretcher

Explanation:

In an AP upright chest radiograph on a stretcher, the X - ray tube's angle must match the angle of the image receptor (IR) to ensure proper alignment for accurate imaging. The patient's chest angle isn't the reference here, the back of the cart is irrelevant, and an angle is required for proper projection.

Answer:

B. Image receptor (IR)
