Please handle with care.The phantom is made
of hard resinous material; the phantom can be
damaged if dropped or hit by a hard object.

Phantom unit B
MRI contrast solution (10mM 10L)
MRI contrast solution
Spout for MRI contrast solution Screwdriver
Extra screws
Instruction manual
*5 levels of concentration, 50mL per bottle
Please clean the phantom with water or
pH neutral detergent. Please do not use organic
detergent such as thinner.
Please do not store in high temperatures,
high humidity or in direct sunlight. It may lead
to deformation or damages.
Please do not write with a pen. Writing directly
on the phantom with felt-tip pen or permanent
marker will not wash off.
Warning
The recommended temperature for use of this phantom is 4 degrees above or below 22 degrees Celcius
according to the NEMA and AAPM standards. For the phantom to be at the same temperature as the scan
room, place the phantom in the room for 24 hours before scanning.
MRI signal materials are sensitive to temperature change. For every 1 degree Celcius of increase, T1 will
increase by approximately 1% and T2 will decrease by approximately 1%.
Additionally, the phantom is composed of plastic material and is prone to damage from excessive force or
reactive solvent.
The MRI is one of the most advanced medical imaging diagnosis method. However, standard uses and
materials for precise product management and maintenance have not yet been dened.
The MRI contrast liquid included in this product has been developed with a focus in safety and has been
featured in the Report of AAPM*. The primary ingredient is nickel dichloride (NiCl ).
The table on page 15 displays the values of T1 and T2 of the magnetic resonance of the nickel dichloride.
Figure 1 on page 16 is a graph of the data on page 15.
Kyoto Kagaku's phantom includes contrast solution of 5 dierent levels of concentration to compare with
the 10mM solution as a standardization product.

2. Loosen and remove the screws of the phantom lid with the screw driver. Do not remove the
white plugs at this time. Please take care not to damage the screws when unscrewing.
1. Remove the cap on the MRI contrast
liquid container, and attach the spout
on the opening. Prepare a container
(ie. beaker). Open the spout and carefully
tilt the box to pour the solution into the
container.
3. Carefully pour the nickel chloride solution into the phantom, lling up to 50% to 80% of the body.
4. Once the lid is attached back on the main body of the phantom, tilt the phantom to remove any air
bubbles in the solution.
5. Remove the white plugs and pour in the
contrast solution through the opening to
completely ll the phantom.
At this point, apply a small amount of
jelly to the rubber portion between the
lid and the main body of the phantom.
Caution: Please use the "V" mark to align the
lid and the main body of the phantom.
6. Insert one plug. Tilt the phantom and remove any remaining air bubbles in the solution.
7. Insert the second plug. Be sure to not add
any air bubbles.
T1 and T2 values are heavily dependent on the temperature change; please take extreme care in
maintaining a consistent temperature when the phantom is in use. Leave the phantom with the
contrast solution in room temperature for over 24 hours to retain a consistent temperature for the
product. Raw materials used to manufacuture the provided nickel dichloride solution is manufactured
in 23 degrees Celcius with relative humidity of 40%.
