The Mini-Phantom can be used to check the alignment of the internal and external lasers to the radiographic center of CT and PET/CT units and to verify lateral gantry angle. It can also be used with accelerator units to check vertical and lateral gantry angles, laser alignment and vertical table movement.

The Mini-Phantom is made of clear acrylic measuring 15 cm x 15 cm x 5 cm thick. One 15 cm x 15 cm side has centering scribe lines that go all the way across the phantom. All four of the 5 cm x 15cm sides are scribed through the center and two opposite sides are also scribed at 5 cm from center. The scribe lines are 1.3mm wide and white for ease of viewing the lasers. All four 5 cm x 15 cm sides have three pinholes, one at center and two at 5 cm from center. The center pinholes are 1.5 mm dia to hold a tungsten pin and the other pinholes are 1.0 mm. Four 1.5 mm dia tungsten pins are included with the mini-phantom.

The two large holes are 9.5 mm in diameter and are 10.6 cm apart from center to center. Each hole is in the exact center of a quadrant of the phantom.

Leveling Platform for Mini-Phantom
The Leveling Platform for the Mini-Phantom is made of black acrylic that is 15 cm square x 1.0 cm thick. A hole in the center of the Mini-Phantom is for a tungsten pin that goes into the Mini-Phantom. A bubble level and three leveling screws with rubber tips are used to level the platform. The rubber tips help prevent the platform from moving.
