Abstract:
An imaging system includes an analog-to-digital converter configured to convert an analog pixel value into a first digital pixel value. The imaging system also includes an index value source configured to receive the first digital pixel value from the analog-to-digital converter and to generate a digital index value based on a comparison of the first digital pixel value to a digital reference value. In addition, the imaging system includes a transmitter in communication with the index value source and configured to transmit the digital index value. Further, the imaging system includes an image processing component configured to receive the digital index value and to generate a second digital pixel value based at least in part on the received digital index value and a lookup table of the image processing component.
Abstract:
The present disclosure presents systems and methods for correcting image artifacts on an x-ray image. X-ray images are obtained and processed with a correction algorithm that generates corrected pixel lines having pixels with corrected pixel values. The corrected pixel lines can then be processed with a filtering algorithm that generates filtered pixel line having pixels with a filtered pixel value. The bad pixel lines are replaced by the filtered pixel lines to generate corrected x-ray images.

Abstract:
A method of imaging a patient and an X-ray dosimetry system are provided. The X-ray dosimetry system includes a support platform configured to support an object to be imaged and a digital X-ray dosimeter mounted on a surface of the support platform, the X-ray dosimeter configured to receive incident radiation prior to the incident radiation having passed through the object to be imaged, the X-ray dosimeter comprising a thickness of less than about four millimeters.

Abstract:
An x-ray system with multiple dynamic range selections. The system including an x-ray source and a detector, wherein the detector includes a scintillator and a pixel. The pixel includes a photodiode and first and second capacitors connectable to the photodiode. The pixel is configured to be switched between a first state where only the first capacitor is connected to the photodiode and a second state where both capacitors are connected to the photodiode. The x-ray source directs x-rays to the detector and a region of interest positioned between the source and detector, the scintillator converts the x-rays to light, and the pixel photodiode converts the light to an electrical charge. The charge is stored in the first capacitor when the pixel is in the first state and in the first and second capacitors when the pixel is in the second state.
