A local radio frequency coil assembly adapted to receive an associated patient to be scanned in a magnetic resonance imaging scanner, the assembly comprising: a patient carrier having an abutment surface; an adjustable coil part including an anterior coil; a rigid coil body (16, 18) including a head coil and a posterior coil, the rigid coil body and the adjustable coil part defining a pediatric patient receiving region configured to receive the carrier; the rigid coil body being configured to be mounted to a patient support table of the magnetic resonance imaging scanner; at least one bearing (34, 36) for operably connecting the adjustable coil part to the rigid coil body (16, 18), the adjustable coil part thereby being pivotally mounted to the rigid coil body at a hinge axis to pivot between an open position and a selected position above a portion of the carrier, wherein the at least one bearing (34, 36) is mounted for movement along a sloping surface such that the adjustable coil part is pivoted and biased relative to the carrier, wherein the at least one bearing (34, 36) and the adjustable coil part are arranged for being biased by at least one of gravity or spring force to move towards the carrier along the sloping surface; an interlock assembly which includes a ratchet member that extends from the adjustable coil part and is configured to engage the abutment surface of the carrier to hold the adjustable coil part in the selected position; and a biasing arrangement which is configured to bias by at least one of gravity or spring force the ratchet member of the interlock assembly into engagement with the abutment surface of the carrier to hold the adjustable coil part in the selected position. a patient carrier having an abutment surface; an adjustable coil part including an anterior coil; a rigid coil body (16, 18) including a head coil and a posterior coil, the rigid coil body and the adjustable coil part defining a pediatric patient receiving region configured to receive the carrier; the rigid coil body being configured to be mounted to a patient support table of the magnetic resonance imaging scanner; at least one bearing (34, 36) for operably connecting the adjustable coil part to the rigid coil body (16, 18), the adjustable coil part thereby being pivotally mounted to the rigid coil body at a hinge axis to pivot between an open position and a selected position above a portion of the carrier, wherein the at least one bearing (34, 36) is mounted for movement along a sloping surface such that the adjustable coil part is pivoted and biased relative to the carrier, wherein the at least one bearing (34, 36) and the adjustable coil part are arranged for being biased by at least one of gravity or spring force to move towards the carrier along the sloping surface; an interlock assembly which includes a ratchet member that extends from the adjustable coil part and is configured to engage the abutment surface of the carrier to hold the adjustable coil part in the selected position; and a biasing arrangement which is configured to bias by at least one of gravity or spring force the ratchet member of the interlock assembly into engagement with the abutment surface of the carrier to hold the adjustable coil part in the selected position.
