Provided are a circuit board and a display device having the circuit board. A 3D anatomical structure detection and segmentation module is trained offline by learning anatomical structure appearance using the set of expertly delineated anatomical structures. In particular, one aspect of the invention relates to a separationconcentration device which comprises at least a first chamber and a second chamber connected by a first valve, whereby operation of the first valve controls the material transfer from the first chamber to the second chamber. A detection unit configured to detect a displacement between the projection surface and a portion of the housing, the housing being configured to support the display unit, the projection unit, and the detection unit.
