The hand, foot, and wrist were grouped together due to having similar part thickness. A hand, foot, and wrist are small enough to NOT need a grid. This made all parts have the same kVp of 60. We based the hand off previous experiments and set technique for the rest of these parts off of that hand adjusting mAs as needed for more photons.
HAND
HAND
*PA Hand:
This Image is optimal because the long axis of the hand is parallel to the IR. There is also no rotation and you can tell because the metacarpals are symmetrical.
PA Hand
60 kVp 0.63 mAs
No grid
10x12 FOV
40" SID
DI -0.2
Oblique Hand
60 kVp 0.63 mAs
No grid
10x12 FOV
40" SID
DI -0.5
Lateral Hand
60 kVp 1.25 mAs
No grid
10x12 FOV
40" SID
DI 0.2
FOOT
FOOT
*AP Foot:
This Image of the foot is good because there is no rotation of the foot. The metatarsals and phalanges have symmetry on both sides.
AP Foot
60 kVp 1 mAs
No grid
10x12 FOV
40" SID
DI -0.2
Oblique Foot
60 kVp 1.1 mAs
No grid

*Lateral Wrist:
This Image is good because the wrist is in a true lateral position meaning the ulnar head is superimposed over the distal radius.
PA Wrist
