Answer to Question 1

perpendicular

Rationale: The AP oblique knee with either medial or lateral rotation uses a perpendicular beam. The primary focus on the AP oblique is not the femorotibial joint, but rather the femoral condyles and/or proximal tibiofibular joint.

Answer to Question 2

pocket dosimeter

Rationale: The pocket dosimeter resembles a fountain pen. It contains an ionization chamber that can be self reading or non-self reading. The greatest advantage of this device is that it can give an immediate reading.
