Reinstein EZ-Cube Phantom

Features

• Output constancy measurements for photon and electron beams
• Depth dose constancy measurements for photon and electron beams
• Superior phantom alignment stability and ion chamber positioning reproducibility
• Rapid, precise and reproducible ion chamber depth changes (from 1 cm to 12 cm depth at 0.5 cm intervals) while maintaining constant TSD.
• Easily readable and unambiguous ion chamber depth scale.
• Output plus depth dose constancy measurements at 90°, 180°, 270° gantry angles.
• One phantom setup for all output and energy constancy measurement depths.

The Reinstein EZ Cube Phantom is a radiation oncology QA phantom that provides rapid and reproducible ion chamber positioning from 1 cm to 12 cm depth at 0.5 cm intervals. Its unique design allows placement of the ion chamber through a range of depths, without ever having to readjust the phantom position with respect to the central axis or its TSD. This can save substantial amounts of time and reduce misalignment. The Reinstein EZ Cube Phantom is designed to simplify testing of beam output plus enregy constancy at three gantry angles: 90 degree, 180 degree and 270 degree.

The EZ-Cube is machined from white acrylic, and contains 3 leveling feet and highly visible cross hair alignment marks on its anterior and lateral faces for precision setup. A channel is milled into the acrylic cube and contains a set of inserts of varying thicknesses which are stacked to fill the channel. A single 2-cm thick plastic insert contains a custom hole to fit a thimble-type ionization chamber. The ion-chamber can be easily positioned along the LINAC central axis from depth of 1 cm to depth of 12 cm by arranging the plastic inserts in different order. Also note that full scatter conditions are maintained at all depths.
