Patent number: 9935152Abstract: Exemplary embodiments are directed to imagining detectors and methods of fabricating the imagining detectors for use in medical imagining systems. In exemplary embodiments, a detector for an imaging device include a continuous unpatterned photoelectric material that forms a portion of a photosensor and an electrode disposed with respect to the photoelectric material to form an anode or cathode of the photosensor. Data readout lines connected to the outputs of transistors of the detector can be susceptible electronic noise from capacitive coupling between the electrode of the photosensor. In exemplary embodiments of the present disclosure, a lateral offset and/or vertical offset between the electrode and the data readout lines can be formed to control the capacitive coupling between the electrode and the data readout line.Type: GrantFiled: December 27, 2012Date of Patent: April 3, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Aaron Judy Couture, Gautam Parthasarathy, Jie Jerry Liu
