500107 Rev 04Chapter 1 - Patient SafetyTrainingThis manual contains detailed information on the setup, positioning, and use of theInvivo Corporation coil. The instructions should be read carefully and thoroughlybefore attempting to scan patients with the coil.QualityAssuranceThe procedure described in the Quality Assurance Section of this manual shouldbe performed upon receipt of the coil to establish a baseline of coil performance.The procedure should be repeated at regular intervals.IndicationsContraindicationsThe coil is indicated for use, on the order of a physician, in conjunction with anMR scanner as an accessory to produce images of the shoulder.The operator should be aware of the following contraindications related to thestrong magnetic field of the MR system:Scanning patients who have electrically, magnetically, or mechanically activatedimplants (for example, cardiac pacemakers) is contraindicated. The magneticand electromagnetic fields produced by the MR system and coil may interferewith the operations of these devices.Scanning patients who have intracranial aneurysm clips is contraindicated.PrecautionsPrecautions should be taken when scanning patients with the followingconditions:Greater than normal potential for cardiac arrestIncreased likelihood for developing seizures or claustrophobiaUnconscious, heavily sedated, or confused mental or physical stateInability to maintain reliable communicationsCautionsThe following general warning statements apply to scanning with a magneticresonance system. For further details, review the warnings in your MR systemOperator's Manual.Do not cross or loop cables. Arcing and patient burns could result. Routecables out of the magnet so that they do not touch the patient.6Invivo CorporationModel QSC

500107 Rev 04Assure that the patient is not touching the bore. If necessary, place padsbetween 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 theresponsible physician before continuing the procedure. Pay specialattention to very young, sedated, or other compromised patients who maynot be able to communicate effectively.Patients with ferromagnetic metal should not be scanned because themagnetic field may interact with implanted surgical clips or other ferromagneticmaterials.Persons with cardiac pacemakers or other implanted electronic devicesshould not enter the magnetic field zone delineated by the MR systemmanufacturer.There is a risk to scanning feverish or decompensated cardiac patients.Facial makeup should be removed before scanning because it may containmetal flakes which can cause skin and eye irritation. Permanent eyelinertattoos may cause eye irritation due to ferromagnetic particles.Patients who work in environments in which there is a risk of havingembedded metallic fragments in or near the eye should be carefullyscreened before undergoing an MR exam.Visually inspect the cable insulator jackets, strain reliefs and connectorboxes before each use. If the insulation is broken or if the cable is frayed,immediately discontinue use of the device.EmergencyProceduresIn the unlikely event that a coil creates smoke, sparks, or makes an unusuallyloud 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.Invivo CorporationModel QSC7

500107 Rev 04Chapter 2 - Using theShoulder CoilsSelecting theBest CoilTip!The 4-ch Sense Shoulder Coil 3.0Tincludes a 20 cm diameter coil and a16.5 cm diameter coil. As with allcoils, a smaller coil provides higherSNR. Each coil size is optimized forits respective shoulder volume.The small 16.5 cm coil is designed tofit small to medium size shoulders.This coil will fit the majority of patients,and will accommodate patients up toapproximately 180 lbs.The large 20 cm coil is designed forlarger patients. This coil may be usedwith patients from 180 lbs and above.Assure the correct size shoulder coil isselected before attaching to the coilbase.PositioningtheBaseplateThe 4-ch Sense Shoulder Coil 3.0Tincludes a baseplate to support thecoil. Locking the coil down greatlyreduces motion artifact. The baseplateis designed to rest directly on thepatient support. Position the baseplatenear the magnet end of the patienttable.Locking theCoil to theBaseplatePut the lock down so it fits into thehole on the baseplate and slide thecoil laterally into position.The cablemust point into the magnet for properoperation. Use either angled slot,depending on whether the study is ofthe right or left shoulder. A positioncloser to the center allows the shoulderto be positioned closer to themagnet center, resulting in betterimages.8Invivo CorporationModel QSC

500107 Rev 04Routing theCableThe cable must point into the magnet. Assure that the cable is routed correctlyfor right or left shoulder scans. Do not cross or loop cables. Arcing and patientburns could result. Route cables out of the magnet so that they do not touch thepatient.PatientPositioningThe Shoulder Coils are designed for head first exams only!Have the patient slide his or her shoulder into the coil and relax the shoulderagainst the coil housing. The Shoulder Coil may now be adjusted medially orlaterally, and rotated to fit comfortably on the patient's shoulder.Connectingthe CableThe cable is connected to the systemusing the standard phased array plug.Plug the cable into the Synergy arrayport of the system.ATTENTION: Do not attempt to use theShoulder Coil when it is unplugged.Invivo CorporationModel QSC9

500107 Rev 04Chapter 3 - Quality AssuranceSetup -LargeShoulderCoilPlace the Large Shoulder coil on thebaseplate and slide it into thepatient's left lateral slot. Connect thecoil cable to the baseplate connectoras shown.The phantom positioner base isdesigned with two curvatures, one tofit the LARGE Shoulder coil and oneto fit the SMALL Shoulder coil.Orient the phantom positioner basesuch that it cups the curvature of thecoil in use.Place the phantom positioner baseinto the lateral slots and move ittoward the Shoulder Coil until thetwo curvatures mate.Place the phantom positionerbracket onto the phantom positionerbase. The hooks in the phantompositioner bracket seat directly intothe notches in the phantompositioner base.10Invivo CorporationModel QSC

Chapter 4 - Scanning500107 Rev 04ChannelSelectionThe 4-ch Sense Shoulder Coil 3.0T uses channels 1, 2, 3, and 4. Select theproper channel(s) from the channel combination (ch. combination) menu on thesystem operator's console. The following Allowed Channel Combinationinformation is coded into the coil resource file:Coil: SENSE-ShoulderNormal Operation 1, 2, 3, 4Each channel individuallyCoilSelectionAfter connecting the Shoulder Coil to the system, the following coil selection mustbe made at the console:SENSE-ShoulderField of ViewandCoverageThe large shoulder coil is 20 cm in diameter, and therefore has an inherent field ofview (FOV) of 20 centimeters.The small shoulder coil is 16 cm in diameter, and therefore has an inherent fieldof view (FOV) of 16 centimeters.You may use a smaller or larger FOV if desired.SurveyImageThe body coil may be used at any time while the Shoulder Coil is in the scanner. Thisallows a large FOV (400 mm) body coil SURVEY to be performed, which is helpfulin determining the foot-head offset required for imaging the shoulder.IMPORTANT!UsingAutoshimAUTOSHIM is a system software feature that improves image quality. This isdone by improving the magnetic field homogeneity within the FOV selected. Theimprovement in image quality is often dramatic when the selected FOV is far offcenter, and when acquiring SPIR images.SuggestedScanProtocolsInvivo Corporation recommends that you select imaging protocols that have beenestablished by your radiologists. Additional protocols can be found within yourPhilips Application Guides.Invivo CorporationModel QSC23

500107 Rev 04Chapter 5 - Cleaning andStorageCleaningThe 4-ch Sense Shoulder Coil 3.0T, and accessory pads, must be cleaned andstored using the following procedures:• Wipe with a cloth that has been dampened in a solution of 10% bleach and 90%tap water, or 30% isopropyl alcohol and 70% tap water.• Do not pour any cleaning solution directly on the coil or baseplate!• Let the coil housing, base plate, and pads dry before use.• Under no circumstances should the coil be placed into any type of sterilizer.StorageStore the coil and base plate in an air-conditioned scan room or equipment room.To store the coils and baseplate, a storage space of 50.5 cm/19.9 in (width) x 60.5cm/23.8 in (depth) x 28.0 cm/11.0 in (height) is required.24Invivo CorporationModel QSC
