Abstract

A maneuverable RF coil assembly, useful for being maneuvered at both positions: (i) over at least a portion of a neonate immobilized within a cradle at time of MR imaging; and (ii) below or aside the cradle when it is not required for imaging. The maneuverable RF coil assembly comprises at least one RF coil and maneuvering mechanism. The maneuvering mechanism comprises both: (i) a linear reciprocating mechanism for approaching or otherwise drawing away at least one coil to and from the neonate; and (ii) tilting mechanism for placing at least one coil away from the neonate.

Claims

1. A maneuverable radio frequency coil assembly (MRCA) adaptable for use with a neonate cradle, the MRCA comprising:

a radio frequency (RF) coil disposed within a housing;

a sliding mechanism, wherein the sliding mechanism is coupled to or formed within the housing, the sliding mechanism configured to allow the housing to slide linearly along an axis that is parallel to a longitudinal axis of the neonate cradle between a first linear position and a second linear position when the housing is coupled to the neonate cradle, wherein the first linear position is located substantially at the same location as the end of the neonate cradle associated with the head of a neonate, and the second linear position is located at a predetermined linear position away from the first linear position in a direction away from the neonate cradle; and

a rotating mechanism, wherein the rotating mechanism is coupled to or formed within the housing, the rotating mechanism configured allow the housing to rotate about the axis between a first rotation position and a second rotation position when the housing is coupled to the neonate cradle, wherein the first rotation position is a position such that were the housing to also be in the first linear position the housing would be capable of receiving at least a portion of the head of a neonate position on the neonate cradle, and the second rotation position is a predetermined rotatable position about the axis.

2. The MCRA according to claim 1, wherein said housing is capable of being moved in a plurality of consecutively maneuverable movements.

3. The MCRA according to claim 1, wherein said housing is capable of being positioned in a plurality of positions.

4. The MCRA according to claim 1, wherein at least one of:

a. said MCRA comprises a handle configured for maneuvering the housing by a MCRA handler;

b. each of said sliding mechanisms and rotating mechanisms is comprises one of;

an automated mechanism, a manual mechanism, a semi-automated mechanism, and a remote controlled mechanism;

c. said MCRA comprises a least one latch configured to secure at least one position of the housing; and

d. said MCRA comprises at least one sensor configured to sense one or more of;

a structural integrity of said RF coil, a structural integrity of said maneuvering mechanisms, a position of said RF coil, a proximity of said neonate to said RF coil, a received RF signal, and a transmitted RF signal.

5. The MCRA according to claim 1, wherein at least one of:

a. said RF coil comprises a plurality of RF coils;

b. said RF coil is configured to connect to at least a second RF coil; and

,

c. said RF coil is connected to at least a second RF coil by a maneuverable connection.

6. The MCRA according to claim 1, wherein at least one of:

a. said RF coil is one or more of a;

solenoid coil, a planar coil, a volume coil, a surface coil, and a quadrature coil;

b. said RF coil is a multi-tuned RF coil; and

,

c. said RF coil comprises a multi-channel RF coil reconfigurable between a plurality of operational modes.

7. The MCRA according to claim 1 wherein said housing is configured to close an opening of an incubator when in the first linear position and first rotation position.

8. The MCRA according to claim 1, wherein said RF coil is a solenoid coil.

9. The MCRA according to claim 1, wherein the housing is not rotatable unless the housing is in a linear position such that when a neonate is located on the neonate cradle, rotation does not interfere with the head of the neonate.

10. The MCRA according to claim 1 wherein:

the housing is a structure having a base and a wall, such that when the housing is in the first linear position and the first rotation position, the base is configured to receive at least the portion of the head of the neonate and the wall extends from the base along the axis;

the housing has a recess located along the wall, said recess extending from the base of the structure along at least a portion of the length of the wall, wherein the size of the recess is configured to permit life support equipment to extend to the head of a neonate position on the neonate cradle without the life support equipment being inside the RF coil.

11. The MCRA of claim 10, wherein the structure has a substantially cylindrical shape and wherein the wall is a curved wall.

12. The MCRA of claim 1, wherein the sliding mechanism is configured to mate with a sliding mechanism associated with the neonate cradle.

13. The MCRA of claim 1, wherein the rotating mechanism of the housing is configured to mate with a rotating mechanism associated with the neonate cradle.
