Patient alignment device

A patient alignment device, comprising:

• a) a table,
• b) first and second board segments, the first and second board segments being supported by the table and having generally flat surfaces, the first board segment having a length which is greater than a length of the second board segment, wherein the first and second board segments have mating curved edges such that either of the first and second board segments can rotate while another of said board segments is fixed,
• c) first and second pins, removably inserted in holes formed in the second board segment, and a third pin, removably inserted in a hole formed in the first board segment, wherein all of the pins comprise means for engaging a respective board segment with the table,
• d) a pair of connectors which removably join the first and second board segments, and
• e) a motor, connected to rotate the first board segment,
• wherein the device can be configured in first and second modes,
• wherein a first mode comprises a condition wherein the connectors are affixed to the board segments, and wherein only one of the pins is inserted in one of said holes, and wherein rotation of the first board segment causes the first and second board segments to rotate as one unit, and
• wherein a second mode comprises a condition wherein the connectors are removed from the board segments, and wherein all three of said pins are inserted into their respective holes, and wherein rotation of the first board segment causes the first board segment to rotate while the second board segment is prevented from rotation.
