Answer to Question 1

edge enhancement

Rationale: Edge enhancement improves visibility of small, high contrast structures.

Answer to Question 2

perpendicular to the femorotibial joint

Rationale: The sthenic patient measures between 18-24 cm from the ASIS to the tabletop which elevates the patient's leg, positioning the tibial plateau perpendicular to the image receptor. Therefore, the CR is directed perpendicular through the femorotibial joint.
