| The
small-size of this phantom makes it highly
portable for convenient QC testing. The
unique configuration eliminates the need
for multiple holes and plugs. |

| The
Reinstein EZ -Cube Phantom |
|
from MRNI, Inc. 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."

Advantages |
|
|
Simplifies
testing of output versus
gantry angel, which is difficult
to accomplish by other phantoms. |
| |
Provides
rapid and reproducible Ion
chamber positioning at 0.5cm
steps, without the annoying
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. |
