53
KBP
Higher KBP = More shades of gray (low contrast) = good for chest X-ray (and looking at soft tissue) Lower KBP = Less shades of gray = looking specifically for bone (thoracic spine = 75KBP)
54
1'' = ?
2.54cm
55
Tube tilt
Reduce distance 1'' for every 5˚ of tube tilt
56
Inverse Square Rule
AP knee, normally done at 40''. If this person has a large butt, their butt is increasing the object to image distance. This would increase magnification. Let's take this out to 84''. 40^2=1600 84^2=7056. Let's say you would normally do this at 70kVP w/12MAs at 40''. 7056/1600=4.41 12MAsx4.41=53MAs
57
Filter
We use a filter on the thoracic spine to even out tissue thickness, put thick part on top to even out the thinner side Otherwise, we would overexpose thin parts and underexpose thick parts
58
Grid
Reduces scatter and makes image sharper, use if >10cm
59
Anode heel effect ---> the central ray is
Decreased @ Anode End Increased @ Cathode End When you x-ray a body part that varies in thickness, you want the anode side of the tube toward the thinner area
60
Exposure
Higher mAs = Darker image (higher exposure) | Higher SID = lighter image (lower exposure)
