Abstract
For the purpose of providing an MRI coil capable of improving an SNR (signal-to-noise ratio), such an MRI coil is comprised of a pair of multi-turn coils 20A and 20B disposed to face each other in an x-direction across a space for accommodating a subject, and the center of turns of the multi-turn coil 20A is biased in a (−y)-direction, and the center of turns of the multi-turn coil 20B is biased in a (+y)-direction.
Claims10
An MR imaging method comprising the step of:
- employing an MRI coil having a pair of coils disposed to face each other across a space for accommodating a subject, at least one of said coils being a multi-turn coil.
An MR imaging method comprising the step of:
- employing a pair of multi-turn coils disposed to face each other across a space for accommodating a subject, said pair of multi-turn coils having at least one of the number of turns and the pitch differentiated between the coils.
An MR imaging method comprising the step of:
- employing an MRI coil having a plurality of coils disposed at different angular positions on an outer periphery of a bobbin surrounding a space for accommodating a subject, at least one of said coils being a multi-turn coil.
An MR imaging method comprising the step of:
- employing an MRI coil having a plurality of multi-turn coils disposed at different angular positions on an outer periphery of a bobbin surrounding a space for accommodating a subject, said plurality of multi-turn coils having at least one of the number of turns and the pitch differentiated between the coils at adjacent angular positions.
An MRI coil comprising:
- a pair of coils disposed to face each other across a space for accommodating a subject, at least one of said coils being a multi-turn coil.
An MRI coil comprising:
- a pair of coils disposed to face each other across a space for accommodating a subject, said coils being multi-turn coils, and having at least one of the number of turns and the pitch differentiated between the coils.
An MRI coil comprising:
- a plurality of coils disposed at different angular positions on an outer periphery of a bobbin surrounding a space for accommodating a subject, at least one of said coils being a multi-turn coil.
An MRI coil comprising:
- a plurality of multi-turn coils disposed at different angular positions on an outer periphery of a bobbin surrounding a space for accommodating a subject, said plurality of multi-turn coils having at least one of the number of turns and the pitch differentiated between the coils at adjacent angular positions.
An MRI coil comprising:
- a plurality of coils disposed side by side along a space for accommodating a subject, at least one of said coils being a multi-turn coil.
An MRI coil comprising:
- on one side of a pair of planes facing each other across a space for accommodating a subject, a plurality of multi-turn coils disposed side by side, and also on the other side, a plurality of multi-turn coils disposed side by side, opposite ones of said multi-turn coils having at least one of the number of turns and the pitch differentiated between the coils, and adjacent ones of said multi-turn coils having the same number of turns and the same pitch or having at least one of the number of turns and the pitch differentiated between the coils.
