Introduction — Patient Positioning and Coils

The Echelon OVAL MRI System Patient Positioning and Coils Manual is designed to guide you through the operation of the Hitachi Echelon OVAL MRI System. The Echelon OVAL MRI System Patient Positioning and Coils Manual details the patient screening and positioning processes and the selection and positioning of radio frequency (RF) coils.

This manual is your guide to working with patients. It explains the essential elements of patient screening and provides basic recommendations for your facility’s patient screening policies and procedures. It also guides you in preparing and positioning patients for the scanning process. Chapter 1 gives you the information you need to achieve three other important goals:

• Dispelling patient misconceptions about magnetic resonance imaging (MRI)

• Alleviating patient concerns about the procedure

• Minimizing patient discomfort during the exam

Chapters 2 and 3 explain how to properly position a patient in each of the coils available for use with the Echelon OVAL MRI System. The illustrations and text are designed to guide you in the proper use of each coil.

Safety

Properly used, the Echelon OVAL MRI System is safe and effective. Misusing the system could result in death or serious injury to patients, staff, or ancillary personnel. For detailed safety information, refer to the Echelon OVAL Equipment Description and Safety Manual.

CautionFederal law restricts this device to sale by or on the order of a physician (or properly licensed practitioner).

CautionAuxiliary equipment (such as physiological monitoring equipment) that is not MRI-compatible should not be used with the MRI equipment. This auxiliary equipment may adversely affect the operation of the MRI system, may be adversely affected by the MRI system, and may result in erroneous readings.

CautionHitachi has provided recommended protocols that have been tested and proven to deliver good image quality. If the user deviates from these recommended protocols, Hitachi cannot guarantee image quality.

CautionThe Echelon OVAL MRI System is limited by United States Federal Law to investigational use for any indications not listed in the Food and Drug Administration (FDA) 510(k) Indications for Use statement.
