The CR angle for AP axial toes
15 degree
CR angle for AP axial Foot
10 degrees
Foot position for the AP Tib/Fib
the ankle is flexed until the the foot is verticle
CR entry point for AP
1/2 inch below
the three positions for homblad method
Standing with knee on stool, standing with knee against board, kneeling on table
30- to 45- degrees
The 2nd through 5th bases of the metatarsals do this in a properly positioned AP Foot
Overlap
The distance the IR should be beyond the joints
1 to 1 1/2 inches
If the patient has a large pelvis (<24 cm) the central angle will be this for AP and Oblique
3-5 degrees cephalad
Flexion of the knee for holmblad method
70 degrees from the IR or 20 degrees from the central beam
The CR entrance point of AP and Oblique
third MTP joint
The reason the medial oblique is preferred over the lateral oblique
The plane through the metatarsals is more parallel to the IR
The SID for AP Tib/Fib
48 inches to capture more anatomy
If the patient has a thin pelvis (<19 sm) the CR angle for lateral knee is this
5-7 degrees cephalad
CR angle of the camp-coventry is perpendicular to this
The long axis of the lower leg
The position of the plane of the MTP joints for a lateral toes
Perpendicular to the IR
Rotation for medial Oblique foot
30 degrees
Patella position for lateral tib/fib
perpendicular to the IR
The positioning for the unaffected leg for a lateral knee
extended behind the affected
How much is the knee flexed for the beclere method
60 degrees
Evaluation of the plantar surface of the phalanges in an lateral toes
The plantar surface is concave
The fibula position for a lateral foot
Overlapping the the posterior portion of the tibia
The fibula is superimposed at these two places in the lateral tib/fib
Proximal fibular head and distally over the posterior half of the tibia
The degree of flexion of the knee in a lateral position to show the maximum joint cavity
20 - 30 degrees
The tibial portion of the knee
