OVERVIEW
The Large Field MR Image Distortion Phantom is designed for assessment of image
distortion in whole body MRI for Diagnostics and Radiation Therapy treatment plan-
ning. The phantom’s large size and grid spacing in all three orthogonal dimensions
make it suitable for large bore MRI.
The phantom can be lled with various MR signal-generating solutions. When
empty, the grid/air interface provides good contrast in CT imaging.(When the CT
images of the phantom are to be analyzed by CIRS MRI Distortion Check Software,
it is highly recommended that the phantom is lled with liquid for scanning.)
The phantom is marked with cross-hairs for ease of alignment to positioning
lasers and can be used on curved and at gantry tables. Due to differences in MRI
machine design by manufacturers, the lateral cross-hairs on the phantom may not
align to lasers. This will not inhibit use of the phantom.
The model 604-GS is used in conjunction with CIRS Distortion Check Software.
The 604-GS comes with a complimentary 90-day license for 5 scans using this
cloud-based software. For instructions on how to create your account, go to

PHANTOM DESCRIPTION
The phantom is a liquid llable, acrylic cylinder 356 mm (OD) by 300 mm in length.
The entire volume is lled with an orthogonal 3D grid of 3 mm diameter rods provid-
ing complete geometric data throughout the imaging volume.

USE OF THE PHANTOM
INITIAL SETUP
The phantom is packed and shipped assembled.
Inspect the phantom for any signs of possible damage that could pose a potential
leak.
If phantom is damaged, notify CIRS or your distributor.
LEAK TEST
The phantom has been leak tested by sustained pressure testing to 2 psi (13.8 kPa)
above hydrostatic pressure. The user is encouraged to perform a leak test with wa-
ter prior to use. A leak with water is much easier to clean than MR doped liquids.
After lling with water, position the phantom on dry paper and let sit for approxi-
mately 1 hour. Inspect for wet spots.
If a leak is evident, notify CIRS or your distributor.
FILLING THE PHANTOM
For safety, familiarize yourself with lling and draining operation prior to lling the
phantom with water or test substances.
The phantom is susceptible of producing artifacts in MRI, especially at 3T, if the
phantom is lled with water only. Such artifacts affect the performance of the algo-
rithm in detecting the grid intersections. It is recommended to ll the phantom with
a solution as recommended by AAPM Report 100 for eld strengths ≤ 3T:
1L H2O, 3.6g NaCl, and 1.25g pure CuSO4 or 1.96g CuSO45H2O.
For eld strengths ≥ 3T, it is recommended that you consult published specialty
literature for choosing the most appropriate lling liquid.
Mineral oil and a mixture solution of water and triethylene glycol are reported as be-
ing effective in reducing artifacts. Use caution and due diligence when researching
a lling liquid best for your application.
We recommend lling the phantom in the following manner:
1. Ensure front plate of the hous-
ing is secured. The gasket
for the front plate should have
light, even pressure on the front
plate.
2. Remove both lling port caps
from the top of the housing to
ventilate phantom.

5
HANDLING AND CARE
The phantom is manufactured from PMMA. It is recommended that the phantom
only be cleaned with mild detergent and water.
CAUTION: Do not use any abrasives, rubbing alcohol, or solvents on the
phantom. These will irreversibly damage the phantom.
The strap harness included can be used to transport the phantom especially when
lled with test uid. Ensure the buckles are attached on the front and rear ends of
the phantom. The straps can be tensioned at the buckle locations. The harness
can remain on the phantom if desired during use.
DRAINING THE PHANTOM
1. Remove filling port cap from front plate.
Water or test substance will begin to slowly
drain from the housing. A catch vessel may
be needed to capture test fluids.
2. Remove one (1) of the filling port caps from
the top of the housing to vent for air. Test
fluids will begin to drain faster.
3. Replace filling port caps when housing is
fully dried.
3. Place funnel into one of the lling ports at the top of the housing.
4. SLOWLY ll the phantom with water or test substance through the funnel.
Note: this should take approximately 15 minutes.
• FILLING THE PHANTOM WITH TAP PRESSURE CAN CAUSE
EXCESS PRESSURIZATION ON THE HOUSING WHICH CAN
LEAD TO CATASTROPHIC FAILURE.
5. Remove funnel and replace both lling port caps.

6
STORAGE
CIRS has tested the 3D grid which maintains geometric stability when the tank is
lled. The PMMA housing is hygroscopic which can jeopardize the integrity of the
phantom if left lled over a long period of time.
Through water absorption on the inside of the housing, the PMMA exhibits a differ-
ential distortion through the inside expanding and outside remaining at atmospheric
conditions. This affects different components of the housing and can lead to failure
of the glue joints.
It is highly recommended that the phantom be drained for long-term storage. Re-
move one of the lling port caps from the top of the phantom to allow the inside to
dry after ridding test uids.
