Automated tuning and frequency matching with motor movement of RF coil in a magnetic resonance laboratory animal handling system

In a magnetic resonance device (MRD) comprising a first input port and a second input port, and at least one magnetic source configured to provide said MRD with a main effect of magnetic field having frequency Mm;

• and animal handling system comprising:
• a first elongated enclosure having a 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 slidably insertable into said first elongated enclosure;
• at least one RF coil configured to provide said MRD with an RF magnetic field having frequency M RF;
• and an automated RF tooting system comprising a motor and a non-transitory 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 and said MRF, in a manner that when said MM and said MRF are substantially different, operating said motor by means of said non-transitory computer readable medium in order to relocate said at least one RF coil thereby tuning said RF magnetic frequency MRF in order to align with said main magnetic frequency MM, wherein said motor is a DC stepper motor.
