The central ray for the lateromedial fan lateral hand is directed to:
2nd proximal interphalangeal joint
2nd metacarpophalangeal joint
1st metacarpophalangeal joint
3rd metacarpophalangeal joint
2nd metacarpophalangeal joint
Rationale: The lateral hand will rotate the thumb side up in position creating a lateromedial projection. The metacarpals should be superimposed and are of primary interest. The fingers should be separated. The central ray is directed to the 2nd metacarpophalangeal joint (MCP) and collimation is to include the entire hand and 1 inch of the distal radius and ulna.
