Abstract

A digital X-ray detector includes a pixel array that includes multiple pixels arranged in rows and columns, wherein each pixel includes a photodiode and a transistor. The digital X-ray detector also includes a scan line coupled to each pixel in a first dimension, a data line coupled to each pixel in a second dimension, enable circuitry coupled to the transistor of each pixel for enabling readout of the photodiode, and readout circuitry coupled to the photodiode through the transistor of each pixel for reading out data from the photodiode. The digital X-ray detector is configured to autonomously determine a start of an X-ray exposure while the enable circuitry maintains each transistor in an off state.

Description

technical field [0001] The subject matter disclosed herein relates generally to x-ray imaging systems, and more particularly to x-ray imaging systems using digital detectors. Background technique [0002] The advent of digital X-ray detectors has brought enhanced workflow and high image quality to medical imaging. However, many of the older analog radiography systems employ conventional X-ray imaging using film cassettes and / or computed radiography (CR) cassettes. There is a desire to upgrade these analog radiography systems to digital radiography systems by replacing film or CR cassettes with digital X-ray detectors to improve workflow and image quality. In order to obtain images from these conventional analog X-ray imaging systems, the film or CR cassettes must be shipped and handled after each exposure, causing time delays in obtaining the desired images. Digital Radiology offers an alternative that allows image data to be acquired and images reconstructed on the spot f...
