CR angle for lateral sacrum/coccyx.
a) 0 degrees
b) 5-10 degrees caudad
c) 20-30 degrees cephalad
d) 45 degrees oblique

Respuesta :

The CR angle for the lateral sacrum/coccyx is usually 5-10 degrees caudad. This means that the central ray (CR) is angled downwards towards the feet by about 5-10 degrees. This positioning helps to provide a better view of the sacrum and coccyx for imaging purposes.
