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.

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%.
