What are the five interactions with matter that can occur? Also out of the five only 3 are applied to radiography can you name them?

Answer:
1) Classical
2) Compton
3) Photoelectric
4) Pair Production
5) Photodisentegration

Numbers 1-3 are the only ones that are useable in radiography. The energy required for 4 and 5 is much to great to be used.

Sunrise Patella

IR size: 10×12 inches

Shielding: Lead shield around waist

Patient Position: Instruct patient to lay supine on the table.

Part Position: Ensure no rotation of the pelvis and flex legs 45 degrees.

Central Ray: Angle CR 15 degrees upshot and palpate the knee to find the patellar joint space. Place the cassette on the thighs oh the patient and angle it to be perpendicular to the CR. You may need to use sponges and tape to hold it in place.

SID: 40 inches

Collimation: Collimate tightly on all sides of the patella

Respiration: patient does not hold respiration.
