A primary benefit of the AP oblique projection, or Grashey method, of the shoulder is that the - ✔ ✔
Glenohumeral and scapulohumeral joints places are open
A radiograph that demonstrates acceptable brightness along one side of the image but not on the
opposite side represents a ___ error (causes a portion of the grid strips to no longer align with the
divergence of the x-ray beam) - ✔ ✔ off-level grid
, A radiograph that demonstrates acceptable brightness in the middle of the image but shows gradually
increasing brightness bilaterally further from the center represents a ___ error
Upside down focused grid
