SUBJECT-LOADED HELICAL-ANTENNA RADIO-FREQUENCY COIL FOR MAGNETIC RESONANCE IMAGING |
摘要 |
Example devices and methods of MRI scanning are disclosed herein. In an example, an MRI scanning system may include a structure defining a bore within which a subject is to be positioned for scanning. The system may also include a magnet to generate a primary magnetic field within the bore parallel to a longitudinal axis of the bore, and a helical-antenna radio-frequency (RF) coil oriented along the longitudinal axis to surround the subject. In addition, the system may include an RF signal generator to drive the helical-antenna RF coil to generate a circularly polarized (CP) RF magnetic field perpendicular to the longitudinal axis, as well as an RF detector to detect a response signal generated by tissues of the subject in response to the CP RF magnetic field. Also included may be a computing system to create an image of the tissues of the subject based on the detected response signal. |
