Page 6: Chapter 1 - Patient Safety
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. -
Page 7: Emergency Procedures
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. -
Page 8: Technical Considerations
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. -
Page 9: Chapter 2 - Using The Hnc-63-Int
Chapter 2 - Using the HNC-63-INT Array Coil IMPORTANT: You must have the Synergy MultiConnect (SMC) Positioning the 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 HNC-63-INT requires a Synergy MultiConnect patch to enable this coil to be recognized by your system. -
Page 10: Positioning The Patient
Rev 05 Positioning the Patient When lifting the anterior coil housing, always grasp the coil by the apron and the superior end of the housing. Never lift the coil housing by the viewing window or mirror. Adjust the patient so their shoulders are snug against the curved arch of the posterior coil housing. -
