  • Patent number: 11737722
    Abstract: Provided are an X-ray detector having fabrication fault tolerant structure and a method for manufacturing the same using a micro-transfer printing (MTP) technique. The X-ray detector may include a photodiode layer formed on a base substrate within a pixel area and including a plurality of photodiode pixel units, a dummy layer formed the base substrate within a peripheral area, a plurality of pixel driving integrated chips printed on the photodiode layer, a plurality of primary column and row integrated chips printed on the dummy layer, and metal lines coupling the column and row integrated chips with pixel driving integrated chips and other constituent elements, wherein the plurality of pixel driving integrated chips and primary column and row integrated chips are manufactured separately from the photodiode layer and the dummy layer and attached on the photodiode layer and the dummy layer, respectively.

  • Patent number: 9420982
    Abstract: The disclosure relates to a mammography device including a main body, a gantry, an X-ray generator, an X-ray detector, a first rotating shaft, a supporting panel, and a pressing panel. The gantry is vertically movably connected to the main body. The X-ray generator is attached to one end of the gantry. The X-ray detector is attached to the other end of the gantry. The first rotating shaft is configured to rotate the gantry. The support panel is configured to support a patient's breast. The pressing panel is vertically movably disposed and connected to the main body. Such a pressing panel is configured to press the patient's breast on the support panel. The X-ray detector acquires 3-D images while rotating the gantry around the breast pressed by the pressing panel and the support panel.
