wherein the entire first sheet of coils is retracted by the storage structure when not in use.
2. The imaging system of claim 1 , wherein the first sheet of coils comprises a plurality of coils that are disposed on one or more layers of a flexible substrate, a rigid substrate, or combinations thereof.
3. The imaging system of claim 2 , wherein the plurality of coils comprises a receiver coil, a transmitter coil, an anterior receiver coil, a posterior receiver coil, a radio frequency coil, or combinations thereof.
4. The imaging system of claim 2 , further comprising a control circuit that is configured to automatically automate or select a subset of coils in the plurality of coils that covers the patient.
5. The imaging system of claim 1 , wherein the storage structure is a fixed structure, a feeder, a mixer, a preamplifier, or combinations thereof.
6. The imaging system of claim 1 , wherein the storage structure is disposed inside the cradle.
7. The imaging system of claim 1 , wherein the storage structure is disposed along a width and inside the cradle.
8. The imaging system of claim 7 , wherein the storage structure stores the first sheet of coils.
9. The imaging system of claim 7 , further comprising a second sheet of coils that is stored inside the cradle, on the cradle or under the cradle.
10. The imaging system of claim 9 , wherein the storage structure is disposed under the second sheet of coils.
11. The imaging system of claim 10 , wherein the first sheet of coils comprises an anterior array of receiver coils and the second sheet of coils comprises a posterior array of receiver coils.
12. The imaging system of claim 1 , wherein the storage structure comprises a spring load arrangement, compression or torsional springs with dampers.
13. The imaging system of claim 1 , wherein the first portion of the first sheet of coils alters based upon the size of a patient lying on the cradle or an anatomical region of the patient to be imaged.
14. The imaging system of claim 13 , wherein the first portion of the first sheet of coils is disposed on the anatomical region of the patient.
15. The imaging system of claim 1 , wherein the first end of the first sheet of coils protrudes out from a slit located near a first edge of the cradle.
16. The imaging system of claim 1 , further comprising a fastener to fasten the first end of the first sheet of coils to a surface near a second edge of the cradle.
17. The imaging system of claim 1 , further comprising a first fastener that is disposed on the first end of the first sheet of coils.
18. The imaging system of claim 17 , further comprising a second fastener that is disposed on a surface near a second edge of the cradle, wherein the first fastener is attached to the second fastener to secure the first portion of the first sheet of coils over a patient.
19. The imaging system of claim 18 , wherein the first fastener and the second fastener comprise a hook and loop strip or non-metallic snap-on buttons or latches.
20. The imaging system of claim 18 , wherein the cradle is configured to retract the first portion of the first sheet of coils when the first end is unfastened and released.
21. An imaging system, comprising:
a cradle;
a first sheet of coils disposed inside of the cradle such that a first end of the first sheet of coils protrudes out of the cradle and a second end of the first sheet of coils is coupled to a storage structure; and
at least a first portion of the first sheet of coils is flexibly pulled out from the cradle by pulling the first end, wherein the first sheet of coils comprises a plurality of coils that are disposed on one or more layers of a flexible substrate, a rigid substrate, or combinations thereof;
further comprising a control circuit that is configured to automatically automate or select a subset of coils in the plurality of coils that covers the patient, wherein the control circuit automatically activates or selects the subset of coils based upon strengths or amplitudes of signals received during a pre-scan of the patient.
22. A method of manufacturing, comprising:
disposing a first sheet of coils inside a cradle such that a first end of a first sheet of coils protrudes out of the cradle and a second end of the first sheet of coils is coupled to a storage structure,
wherein at least a first portion of the first sheet of coils is flexibly pulled out from the cradle by pulling the first end.
23. The method of claim 22 , further comprising disposing the first sheet of coils inside the cradle such that the cradle automatically retracts the first portion of the first sheet of coils or a portion of the first portion of the first sheet of coils when the first end of the first sheet of coils is unfastened or released.
24. The method of claim 22 , wherein the first portion of the first sheet of coils or a portion of the first portion of the first sheet of coils closely and comfortably fits the patient.
