mAs: 10.00

kVp: 58

EI : 3599

DI: 8.5 (very high)

Changes to be made: CR directed to midpoint of leg. Entire tibia and fibula is demonstrated. Knee and ankle joints are demonstrated. Partial superimposition of fibula and tibia at proximal and distal ends. Exposure is high. Collimation could have been brought in to include less of the knee.  Two-sided collimation. Marker present. 

mAs: 10.00

kVp: 58

EI : 3585

DI: 8.5 (very high)

Changes to be made: CR to midpoint of leg. Entire tibia and fibula demonstrated. Knee and ankle joint demonstrated. Proximal head of fibula superimposed by tibia. Distal fibula superimposed over osterior half of tibia. Exposure factors are high. Soft tissue is burned out. Marker present. 

mAs: 10.00

kVp: 80

EI : 2202

DI: 6.4 ( Very high)

Changes to be made: CR paralell to tibial plateaus. CR is a bit too low-should be placed 1/2 inch distal to apex of patella. Femorotibial joint space open. Articular facets profiled. High exposure factor. Soft tissue not visable. 

mAs: 6.30

kVp: 82

EI : 1013

DI: 3.0 (high)

Changes to be made: 45 degree lateral rotation. CR 1/2 inch distal to the apex of the patella. Proximal tibiofibular joint open. Tibial plateaus. Fibula superimposed over lateral half of the tibia. High exposure factors, marker present. Four sided collimation. 

mAs: 4.00

kVp: 82

EI : 615

DI: 0.8 (Good)

Changes to be made: 45-degree medial rotation. CR 1/2 inch distal to the apex of the patella. Proximal tibiofibular joint not open. Tube head angle needed. Fibula superimposed over midtibia. Tibia and fibula are separated at their proximal articulation. Lateral condyles of the femur and tibia visible. Good exposure factors, marker present. 

mAs: 6.30

kVp: 80

EI : 637

DI: 1.0 (Good)

Changes to be made:  Knee is not flexed 20-30 degrees. Insufficient cephalad CR angle. Fibular head and tibia slightly superimposed. Patella is lateral and in profile. Optimal expsoure factors. Marker present. 

mAs: 6.30

kVp: 80

EI : 358

DI: -1.4 (Low)

Changes to be made: Knee is flexed 20-30 degrees. Insufficient cephalad tube angulation. Patella in profile. Over rotated as seen by the over super imposition of the tibia by the fibula. Exposure factors acceptable but not optimal. Marker present. 

mAs: 6.4

kVp: 76

EI : 55

Changes to be made: Knee is fully extended. Femoral condyles are symmetric, and tibia intercondylar eminence is centered. Slight superimposition of the fibular head on the tibia. Open femorotibial joint space, with interspaces of equal width on both sides of the knee. Low exposure. 

mAs: 12.5

kVp: 76

EI : 24

Changes to be made: knee is flexed 20-30 degrees. Patella is in profile. CR is 1/2 inch below the patella apex. Collimation needs to be brought in. Tibia and fibula is more than 1/3rd showing. Marker present. Low exposure.
