RF AUTOMATED TUNING SYSTEM USED IN A MAGNETIC RESONANCE DEVICE AND METHODS THEREOF

摘要

An animal handling system for use in a magnetic resonance device (MRD) device, including: a first elongated enclosure having a proximal end, a distal open end and a first geometry, and a second elongated enclosure having a proximal end, a distal open end and a second geometry. The first geometry comprises a first cross-sectional area that is larger than a second cross-sectional area of the second geometry. The first elongated enclosure is inserted into a first input port of the MRD device and the second elongated enclosure is inserted in a second input port of the MRD device diametrically opposite to first input port. The first elongated enclosure and the second elongated enclosure are inserted into the respective input ports, the second elongated enclosure slides into the first elongated enclosure through the open distal end of the first elongated enclosure.

主权项

1. In an MRD comprising a first input port and a second input port, and at least one magnetic source adapted to provide said MRD with a main effective magnetic field having frequency MM;
an animal handling system comprising:
a first elongated enclosure having a first cross-sectional area; a second elongated enclosure having a second cross-sectional area smaller than said first cross-sectional area; said first elongated enclosure is insertable into said MRD's first input port; said second elongated enclosure is insertable into said MRD's second input port; and said second elongated enclosure is slideably insertable into said first elongated enclosure;at least one RF coil configured to provide said MRD with an RF magnetic field having frequency MRF; andan automated RF tuning system comprising a motor and a computer readable medium configured to perform the following steps: measuring said frequency MM of said main magnetic field; measuring said frequency MRF of said RF magnetic field; comparing said frequency MM and said frequency MRF; and aligning said MM with said MRF, in a manner that if said MM and said MRF are substantially different, operating said motor by means of said computer readable medium to relocate said at least one RF coil thereby tuning said RF magnetic frequency MRF to align with said main magnetic frequency MM.
