Question

question 6/10
what is the recommended central ray entrance point for a lateral chest radiograph?
○ midcoronal plane at the level of t7
○ midcoronal plane at the level of the sternal angle
○ 3 inches (8 cm) anterior to the midcoronal plane at the level of the xiphoid process
○ midaxillary plane at the level of the manubrium

Explanation:

For a lateral chest radiograph, the central ray entrance point is the midcoronal plane at T7 level (heart and mediastinum are centered here). Other options have incorrect planes/levels (sternal angle, xiphoid - related, manubrium - related don't align with standard lateral chest CR entrance).

Answer:

A. Midcoronal plane at the level of T7
