must be included ?
2. For diabetic emergengy a hyperglycemic patient that sugar free liquids
is awake may need
3. Due to the anode angle, the effective focal spot is smaller
usually ______ compared the actual focal spot.
4. overall image density is primary controlled by mAs

with
6. We place thicker anatomy under the cathode side of True
the x-ray to make use of the anode heel effect for a
more uniform radiographic density
