 The Reinstein EZ - Cube Phantom delivers fast, easy and accurate output depth dose constancy measurements for photon and electron beams in accordance with AARPM TG-40 guidelines.
The cube phantom provides quick and accurately changing ion chamber depth without the need for realignment between measurements.
The Reinstein EZ - Cube Phantom is a radiation oncology QA phantom that provides rapid and reproducible Ion chamber positioning from 1cm to 12cm depth at 0.5cm 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. Conventional solid "slab" phantoms often require realignment of the slabs for each change in Ion chamber depth. This can waste substantial amounts of time and lead to misalignment, especially during monthly QA (as recommended by AAPM TG-40) of a dual-photon, multiple-electron beam accelerator.
The Reinstein EZ-Cube phantom is designed to simplify testing of beam output plus energy constancy at three gantry angles: 90°, 180°, 270°, as described in "Comprehensive QA for Radiation Oncology: Report of AAPM Radiation Therapy Committee Task Group 40."
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 1cm to 12cm depth at 0.5cm 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
• Reduction of total setup and measuring times by as much as 75%
• Includes adjustable support leveling legs and a bubble level
Advantages
• Simplifies testing of output versus gantry angel, which is difficult to accomplish by other phantoms.
• Provides rapid and reproducible Ion chamber positioning at 0.5 cm steps, without the need for repeated readjustment of phantom position.
• Eliminates the need to periodically recalibrate or balance detectors - a significant hidden expense with multiple detector systems.
• Is a multipurpose, cost-saving QA and calibration phantom that makes use of your own ion chamber and electrometer.
• Verifies every constancy measurement for photon and electron beams.
