CT Mini-Phantom for ISIS QA-1 Phantom.

This Optional Mini Phantom can be used with the Alignment Bar or the Adjustable Table-Centering Bar to verify the coincidence of the lasers and the crosshairs and to check for gantry sag and optical back pointer position when the gantry is rotated ± 90°.  The phantom can be used in the flat or vertical position.  It has an “L-shaped” pin groove that sits on the alignment pin on either bar.  It is scribed on four sides with 2 mm white painted lines.  There are holes for tungsten pins on four sides of the phantom.  Four 1.5 mm dia. tungsten pins are included.
