Introduction

About this Instruction Manual

The purpose of this instruction manual is to promote the safe use of the SPECTRE and SPECTRE Pico during its expected service life.
It describes the use of the device as intended by the manufacturer.

Identification

Product Name: Spectroscopy Reference Phantom (SPECTRE)

Manufacturer and Contact Information

Intended Use

The SPECTRE and SPECTRE Pico phantoms are designed for Quality Assurance measurements of Magnetic Resonance Spectroscopy (MRS). Phantoms (also known as Quality Assurance Devices) are used in lieu of a human being inside an MRI scanner to assess its performance. The user should refer to the MRI device’s instructions for use to set up the correct pulse sequence for a given outcome. Equivalent acquisition techniques need to be used on the phantom as in the humans / patients.

Intended User

The SPECTRE and SPECTRE Pico phantoms are intended for use by qualified MRI system operating personnel. The device must be used by competent personnel who have the applicable education and experience. This includes but is not limited to:

• Radiographer/MRI Technologist

• Clinical Scientist/Hospital Physicists

• MRI Physicist

• Radiologist

• Students/Researcher

• Other trained Medical Professional.

The device must be used by a skilled person who has the applicable education and experience to enable them to perceive risks and to avoid hazards which operation or maintenance of the device can create

Warnings and Cautions Used

Essential safety descriptions are provided in the instruction manual in the form of either a Warning or a Caution, as described below:

A CAUTION is given when special instructions must be followed. Disregarding this advice can cause damage to the device or other equipment.

All users must familiarise themselves with all the warnings and cautions contained in the instructions before using this device.

Device Description

About the SPECTRE and SPECTRE Pico Phantoms

The SPECTRE (Spectroscopy Reference) and SPECTRE Pico phantoms are designed for Quality Assurance measurements of Magnetic Resonance Spectroscopy (MRS).  It contains a set of metabolites found within the brain at physiological concentrations and pH, all housed within a HDPE spherical shell. SPECTRE and SPECTRE Pico use a set of metabolites typically used in MRS QA; with the addition of GABA (gamma-Aminobytyric acid) at 2mM, to allow performance testing of both standard (e.g. PRESS, LASER) and J-edited (e.g. MEGA-PRESS) MRS acquisitions.

Materials

Storage Instructions

Store

• In a dry and well-ventilated environment

• Between 15 °C and 30 °C

• Out of direct sunlight

If possible, store the phantom in the MRI magnet room. This will ensure that it is at thermal equilibrium with the room and provide the most reliable and reproducible results. Either store in the supplied box, or use the supplied stand to store on a flat surface such as a shelf.

Cleaning

If the SPECTRE or SPECTRE Pico phantom requires cleaning it can be cleaned with soap, water, and a soft cloth or sponge to remove dirt and debris. Organic solvents such as isopropanol may be used to remove sticky residue on the HDPE sphere, however these may cause the labels to stop adhering to the surface.

Operating Instructions

Unpacking

The SPECTRE and SPECTRE Pico phantoms are supplied in a protective cardboard packaging box. To unpack:

1. Inspect the outer packaging. If any damage is present do not use the device. Please contact Gold Standard Phantoms.

2. Remove each component from the box.

3. Inspect each component for damage. If any damage is present do not use the device. Please contact Gold Standard Phantoms.

4. Carefully remove the outer packaging. Do not use a sharp knife in case this cuts or punctures the device.

Use

1. Place the on the MRI scanner couch in close proximity to the RF coil that is being used. It may help to use foam pads provided with the MRI scanner to aid positioning

2. Align the MRI system’s laser with the middle of the phantom.

3. Move the phantom to magnet iso-centre.

4. Begin the MR examination.

5. When finished store the phantom.

Adverse Events

Any adverse events that occur during the use of this device should be reported both to Gold Standard Phantoms and the relevant Competent Authority of the member state.

Warranty

Standard Manufacturer’s Warranty (SMW)
The phantoms carry as 1 year manufacturer’s warranty. This covers assurance regarding quality / lifespan with a promise to repair or replace the SPECTRE and SPECTRE Pico phantom under a standard RMA (return merchandise authorisation). Shipping and Duty charges may apply.

Disposal

Do not allow the contents of the phantom to enter drains, sewers, or watercourses. Dispose of this material and its container as hazardous waste. Disposal should be in accordance with local, state, or national legislation.
