Abstract

An incubator arrangement and radiofrequency (RF) coil are provided for use in a Magnetic Resonance Imaging (MRI) system. The incubator arrangement comprises an enclosure adapted to support a subject in a magnet of the MRI system during imaging and a radiofrequency coil disposed within the enclosure. The RF coil is adapted to provide visual and physical access to the subject, and further adapted to obtain a selected signal to noise ratio.

Claims

1. An incubator arrangement for use in a Magnetic Resonance Imaging (MRI) system:

a base;

a support table attached to said base and moveable thereon, said support able adapted to move to be disposed within an imaging space of said MRI system;

a subject support unit attached to said support table and moveable thereon, said subject support unit being adapted to support an infant;

an enclosure attached to said support table and adapted for receiving said infant on said subject support unit, said enclosure further comprising sliding access panels to provide physical access to said infant, said enclosure being adapted to maintain a selected environment and being further adapted to permit a coupling of a plurality of life support mechanisms to said infant, said enclosure further adapted to provide visual access to said subject; and

,

a radiofrequency (RF) coil disposed within said enclosure and adapted to receive at least a portion of said infant, said RF coil being adapted to provide visual and physical access to said infant, and being further adapted to obtain a selected signal to noise ratio.

2. The incubator arrangement of claim 1 further comprising a cable take up assembly adapted to store and permit tensioned movement of at least one cable that feeds from said enclosure to at least one of external visual and environment controls.

3. The incubator arrangement of claim 1 further comprising a heater tube assembly adapted to transfer temperature controlled air from a heater to said enclosure, said heater tube assembly comprising a plurality of tubes adapted to cooperate to extend and retract as said enclosure is translated along the displacement axis into the magnet of the MRI system.

4. The incubator arrangement of claim 1 wherein said base is further configured for attenuation of RF emissions.

5. The incubator arrangement of claim 4 wherein said base further comprises a plurality of copper lined chambers and a plurality of filtering capacitors coupling leads into and out of said chambers to said copper.

6. The incubator arrangement of claim 1 further comprising a transfer table coupled to said support table and adapted to transfer said infant onto said incubator arrangement.
