Abstract
Devices, methods, and systems including an intraoral x-ray imaging sensor. The intraoral x-ray imaging sensor having a substrate having an imaging area and a non-imaging area, a plurality of readout amplifiers located in the non-imaging area of the substrate, an array of pixels located on the imaging area of the substrate and arranged as a plurality of rows and columns, and pixel selector circuitry diagonally arranged in the imaging area of the substrate. Each pixel of the array of pixels is selectively coupled to one or more of the plurality of readout amplifiers.
Claims23
An intraoral x-ray imaging sensor comprising:
- a substrate having an imaging area and a non-imaging area;
- a plurality of readout amplifiers located in the non-imaging area of the substrate;
- an array of pixels located on the imaging area of the substrate and arranged as a plurality of rows and columns, wherein each pixel of the array of pixels is selectively coupled to one or more of the plurality of readout amplifiers;
- and
- pixel selector circuitry diagonally arranged in the imaging area of the substrate.
A method of capturing an x-ray image with an intraoral x-ray imaging sensor, the method comprising:
- initiating a readout sequence by conveying a signal to pixel selector circuitry, wherein the pixel selector circuitry is diagonally arranged in an imaging area of a substrate of the intraoral x-ray imaging sensor;
- selectively coupling each pixel in a selected row or selected column of an array of pixels located in the imaging area to one or more of a plurality of readout amplifiers;
- receiving, at the one or more of a plurality of readout amplifiers, a signal from at least one pixel in the selected row or selected column;
- and
- outputting a signal from the one or more of the plurality of readout amplifiers based on the signal from the at least one pixel until the readout sequence for capturing the x-ray image is completed.
A dental x-ray system comprising:
- an intraoral x-ray imaging sensor having
- a substrate having an imaging area and a non-imaging area;
- a plurality of readout amplifiers located in the non-imaging area of the substrate;
- an array of pixels located in the imaging area of the substrate and arranged as a plurality of rows and columns, wherein each pixel of the array of pixels is selectively coupled to one or more of the plurality of readout amplifiers;
- and
- pixel selector circuitry diagonally arranged in the imaging area of the substrate;
- and
- a dental image generation device having
- memory;
- and
- one or more processors configured to
