What is the part position for the AP forearm projection?

What is the part positioning of the AP forearm with the elbow extended, hand supinated, humeral epicondyles equidistant from IR, and long axis of forearm aligned parallel?

100

What structure is in profile on the lateral side of the proximal humerus on the AP projection of the humerus?

What is the greater tubercle?

100

For the axiolateral coyle method with a 45-degree angle towards the shoulder, what anatomy are you visualizing? *Bonus points if you can tell me what way the radial tuberosity is facing?

radial head, neck, and tuberosity in profile and free from superimposition w/ the exception of a small portion of the coronoid process. distorted epicondyles. *posteriorly*

200

What is the collimation for the forearm?

What is the radiation field 2" distal to wrist joint and proximal to elbow joint, and 1" on the sides?

200

What is the estimated kVp for the humerus?

What is 70-75 kVp?
300

What has occurred during an AP forearm projection if the proximal and distal aspects of the forearm do not demonstrate even brightness?

What is the proximal forearm having been positioned at the anode end of the tube?

300

What projection of the elbow demonstrates the olecranon in profile?

What is the lateral elbow?

300

What is the anode heel effect?

What is the geometric angle of the anode causing the absorption of photons, resulting in the anode side producing fewer photons at the anode end and more photons at the cathode end?

400

For a lateral forearm projection, what will be demonstrated if the wrist and distal forearm are internally rotated?

What is the demonstration of the distal radius anterior to the ulna?

400

What is the direction and amount of CR angulation for the axiolateral (Coyle method) projection to demonstrate the radial head and capitulum?

What is the CR of 45 degrees towards the shoulder?

500
During an AP forearm projection, if less than 1/8th of the radial head is superimposed over the ulna, what has occurred?

What is the internal rotation of the elbow?
