What is the position of part for the AP Oblique Knee Lateral?
If necessary, elevate the hip of the unaffected side enough to rotate the affected limb. Center IR 1/2 below the apex of the patella. Externally rotate the limb 45 degrees
Position of Part for the Camp-Coventry?
Flex the knee to either 40-50 and rest foot on support, Center the upper half of the IR to the knee joint the central ray angulation projects the joint to the center of the IR. Adjust leg so knee has no medial or lateral rotation.
What is the CR for the PA Patella?
Perpendicular to the midpopliteral area exiting the Patella, Collimate close to the patellar area.
Position of part for the AP Femur (with hip included)?
Proximal femur-which must include the hip joint, place the top of the IR a the level of the ASIS. Rotate limb internally 10to15 degrees to place the femoral neck in profile.
What is the central ray for the Tangential Projection for the Patella?
Perpendicular to the joint space between the patella and the femoral condyles when joint is perp. The angulation is 15-20degress when space is not perp.
What is the largest and strongest tarsal bone?
Calcaneus
What is the position of part for Tangential Projection (Merchant Method)?
Adjust the angle of knee flexion to 40 degrees, may varies 30to90 to demonstrate patellofemoral disorders, Place IR perpendicular to the central ray 1 ft distal to patellae,
What is the structure shown for a Tangential projection(Merchant Method)?
The right angle alignment of the IR and the central ray, the patellae are seen as nondistorded, albeit slightly magnified images.
What are the three positions for the Intercondylar Fossa PA Axial (Holmblad Method)?
1. Standing w/knee of interest in flexed & resting on a stool at the side of the table 2. Standing at side of table w/affected knee flexed & placed in contact w/IR. 3. Kneeling on table w/affected knee over IR. (Patient leans over table for support)
Structures shown for the Camp-Coventry?
Axial image shows unobstructed projection of the intercondyloid fossa and the medial and lateral intercondylar tubercles of the intercondylar eminence.
