SPAN201 is for students who have successfully completed SPAN 110, SPAN 115, SPAN 102, or the equivalent, or have taken the placement exam. 

The _____ the focal spot, the better the resolution.

What are the 2 types of shape distortion?

Using the inverse square law, If the intensity of radiation at 60 inches is 230 mR, what is the intensity if the SID is decreased to 30 inches?

Using the system speed formula: A PA chest x-ray requires 110 kVp, 10 mAs with a 250-speed image receptor. What radiographic technique should be used with a 400-speed image receptor 

Using the direct square formula, If 20 mAs produces an appropriate exposure at a 40 inch SID, how much mAs is needed at a 60 inch SID to maintain that amount of exposure?

Increasing collimating will have what effect on the amount of radiation reaching the IR

What is the most common change in mAs when changing technical factors to improve exposure to an image?

To maintain the same amount of radiation reaching the IR, if the kVp is increased by 15% the mAs needs to
