Posterior
Coil Housing

The HNC-63-INT consists of two housings to facilitate lifting and positioning the coil on the patient cradle
and patient imaging. A latch is located on each side of the housing to secure the housings together and
ensure proper electrical connections between anterior and posterior housings. With latches in the open
position, the anterior housing may be lifted from the posterior housing.

Extreme care should be taken if attempting to move the HNC in one operation. When lifting the anterior housing
from the posterior housing, always grasp the coil by the apron and superior end. IMPORTANT: Never lift the

coil by the rungs in the patient viewing window or by the viewing mirror.

Indications

Contra­indications

This manual contains detailed information on the setup, positioning and use of the
Invivo Corporation coil. Read the insructions carefully and thoroughly before
attempting to scan patients with the coil.

The procedure described in the Quality Assurance Section of this manual should be
performed upon receipt of the coil to establish a baseline of coil performance. The
procedure should be repeated at regular intervals.

The coil is indicated for use, on the order of a physician, in conjunction with an MR
scanner as an accessory to produce images of the brain, cervical spine, anterior
neck, and vasculature of the head and neck, to the aortic arch.

The operator should be aware of the following contraindications for use related to the
strong magnetic field of the MR system:

Scanning is contraindicated for patients who have electrically, magnetically or
mechanically activated implants (for example. cardiac pacemakers). The
magnetic and electromagnetic fields produced by the MR System and coil may
interfere with the operations of these devices.

Scanning patients with intracranial aneurysm clips is contraindicated.

Precautions

Cautions

6

Precautions should be taken when scanning patients with the following conditions:

Greater than normal potential for cardiac arrest

Increased likelihood for developing seizures or claustrophobia

Unconscious, heavily sedated, or confused physical or mental state

Inability to maintain reliable communications

The following general warning statements apply to scanning with a magnetic
resonance system. For further details, review the warnings in your MR system
Operators Manual.

Do not cross or loop cables. Arcing and patient burns could result. Route
cables out of the magnet so that they do not touch the patient.

Assure that the patient is not touching the bore. If necessary, place pads
between the patient and the surface of the bore.

If the patient complains of warming, tingling, stinging, or similar sensations,
promptly stop the scan procedure, examine the patient, and contact the
responsible physician before continuing the procedure. Pay special
attention to very young, sedated, or other compromised patients who may
not be able to communicate effectively.

Patients with ferromagnetic metal should not be scanned because the
magnetic field may interact with implanted surgical clips or other ferromagnetic
materials.

Persons with cardiac pacemakers or other implanted electronic devices
should not enter the magnetic field zone delineated by the MR system
manufacturer.

Rev 05

Emergency
Procedures

There is a risk to scanning feverish or decompensated cardiac patients.

Facial makeup should be removed before scanning because it may contain
metal flakes which can cause skin and eye irritation. Permanent eyeliner
tattoos may cause eye irritation due to ferromagnetic particles.

Patients who work in environments in which there is a risk of having
embedded metallic fragments in or near the eye should be carefully
screened before undergoing an MR exam.

Visually inspect the cable insulator
jackets, strain reliefs and connector
boxes before each use. If the insulation
is broken, or if the cable is frayed,
immediately discontinue use of the
device.

In the unlikely event that a coil creates smoke, sparks, or makes an unusually loud
noise, or if the patient requires emergency assistance:

• Stop the scan if one is in progress.

• Remove the patient from the scan room if medical treatment is needed.

Rev 05

Technical
Considerations

The coil and accessories require special conditions regarding
electromagnetic compatibility. The coil must be installed and used in a
shielded scan room provided with the MR magnet and system. The user
must ensure that the scan room door is closed during system use. Failure
to do so may cause reciprocal interference with portable and mobile RF
communications equipment, affecting the performance of the MR coil and/
or such equipment.

The coil should only be used with the accessories specified in the operator’s
manual.

The use of accessories other than those specified in the operator’s manual
may result in decreased ESD immunity of the coil or MR system, causing
damage to the coil and/or system.

The equipment should not be used with other coils or equipment present in
the MR scanner except as specified in the Operator’s Manual.

Tampering with the cable pins and connector may damage the connector
and affect coil or system performance. Please verify that connector and
pins are not damaged before use.

Chapter 2 - Using the HNC-63-INT

Array Coil

Positioning the
HNC-63-INT
Coil on the
Patient Table

IMPORTANT: You must have the Synergy MultiConnect (SMC)
device and Level 8.1.1 or higher software in order for the Intera
system to recognize the coil. Additionally, Release 8.1.1 software
requires a Synergy MultiConnect patch to enable this coil to be
recognized by your system. Software releases above 8.1.1 do not
require the patch.

The HNC-63-INT Neurovascular Array Coil is designed for imaging of the brain,
cervical spine, anterior neck and vasculature in the head & neck, to the aortic arch.

Polarity (i.e., coil orientation) must be maintained to produce acceptable images. The
coil must be placed on the patient support with the cable exiting the coil on the right, as
you are facing the magnet.The HNC-63-INT coil is designed for head first exams

only!

The HNC coil is designed to rest directly on the patient support. With the anterior coil
housing removed, center the posterior coil housing on the patient support at the magnet
end of the patient support. Position support pad flush with the end of the HNC Coil.

The internal coil pad should be centered on the posterior housing. The pad serves to
provide additional patient comfort during the scan, and helps center the patient in the
coil, and is recommended for optimal coil performance.
