Abstract

The present invention provides a sensor selection device for selecting sensor elements of a magnetic resonance imaging device, the sensor selection device comprising a provider for providing a first characteristic property (601) of a first sensor element (603) within a predetermined scan volume and for providing a second characteristic property (605) of a second sensor element (607) within the predetermined scan volume (215), a means for determining a mutual quantity from the first characteristic property (601) and from the second characteristic property (605), and a selector for selecting or for excluding the first sensor element (601) or the second sensor element (601) based on the mutual quantity.
