1. A compressor wheel for a compressor of a turbocharger, the compressor wheel comprising a hub and a multiplicity of blades on the hub, wherein in intermediate spaces of the multiplicity of blades a channel is in each case formed between a suction side and a pressure side, the channel guiding fluid that flows in axially in relation to a rotation axis and radially or radially-axially outward, wherein the hub in relation to the rotation axis is contoured such that the hub has a rotationally symmetrical portion and a non-rotationally symmetrical portion, wherein on the non-rotationally symmetrical portion a transition between the hub and each of the blades is embodied with a radiused connection and facing the suction side has a region of modified thickness, wherein in at least one channel between the suction side and the pressure side on the hub there is configured a region extending between a peripheral edge of the hub and the transition, and wherein the region extending between the peripheral edge of the hub and the transition is defined by a multiplicity of linear control rays arranged at discrete positions within the at least one channel between the suction side and the pressure side on the hub.
