Alignment Bar, Varian ETR Couch, for ISIS QA-1 Phantom.

The Alignment Bar fits on the couch top for proper alignment of the ISIS Phantom Cube (Item 681-100).  The Alignment Bar is white with engraved black dash lines on the top and all four sides for central axis/laser location.  Each end has a 1.5 mm diameter x 12.7 mm tungsten pin in the center.  There are seven aluminum balls across the top of the bar, one in the center and three on either side at 13, 14 and 15 cm from center.  The three balls on each side are 1/32", 1/16", and 3/32" (0.08, 0.16, and 0.24 cm) in diameter with the smallest ball closest to the center.  The overall size of the bar is 56.52 cm wide, 4.47 cm long and 2 cm thick.  A pin centered on one side of the alignment bar is used to connect the Alignment Bar to the Leveling Platform (Item 681-159) for center alignment on the couch top.
