1. A spine coil array for an imaging system, the spine coil array comprising:
a plurality of coil elements, the plurality of coil elements comprising a first region, a second region, and a third region, wherein the density of the plurality of coil elements changes at least once from the first region to the third region in a first direction within the spine coil array and changes at least once from the second region to the third region in a second direction, wherein the first direction is a direction in which a patient bed is moved and the second direction is at an angle to the direction in which the patient bed is moved, wherein the first region on the patient bed includes a cardiac examination region inside of which the density of coil elements in the first direction is greater than the density of coil elements of the plurality of coil elements that are outside of and adjacent to the cardiac examination region and outside of the second region, in the first direction, wherein the plurality of coil elements comprises a first density of coil elements per unit length running in the first direction, the first density of coil elements comprising the coil elements delimiting the first region, the first region comprising at least two coil elements of the plurality of coil elements, the two coil elements of the first region being arranged adjacent one another in the first direction, and wherein the plurality of coil elements comprises a second density of coil elements per unit length running in the first direction, adjoining the first region, the second density of coil elements comprising the coil elements delimiting the third region, the third region comprising at least two coil elements of the plurality of coil elements, the two coil elements of the third region being arranged adjacent one another in the first direction. |
