    Abstract: A Grid (1) for selective absorption of electromagnetic radiation (2, 3), as used e.g. in CT or NM imaging, comprises a block of a rigid foam material (4), where the foam material is essentially transparent to the electromagnetic radiation (2, 3), a first set of radiation absorbing lamellae (5), and a second set of radiation absorbing lamellae (6), the first and the second set of lamellae are arranged in the block of foam material so that a radiation transmission direction (T) is defined, the first set of lamellae and the second set of lamellae being arranged on top of each other with respect to the transmission direction (T). Such a grid arrangement is rigid due to the use of a carrier material, can be manufactured precisely and, furthermore, two-dimensional grids can be manufactured without the need to physically intersect the lamellae.
