Final answer:
The anterior oblique view of the SC joint typically requires a rotation of 10 to 15 degrees, but the closest option given would be 15 degrees.
Step-by-step explanation:
The anterior oblique view of the sternoclavicular (SC) joint typically requires a rotation between 10 to 15 degrees. The anterior oblique view of the SC joint typically requires a rotation of 10 to 15 degrees, but the closest option given would be 15 degrees. However, protocols can vary between institutions.
It is important that the x-ray technologist follows the specific protocol of their department while ensuring a clear view of the SC joint is obtained.
Since the options provided do not include 10 to 15 degrees specifically, if we had to choose the closest from the options given, 15 degrees of rotation (option a) is most likely to be recommended for the anterior oblique of the SC joint.
