摘要:
An X-ray imaging method includes performing an X-ray exposure via an X-ray radiation source responsive to a source controller. The method also includes sampling X-ray image data via a digital detector without communication of timing signals from the source controller. The method further includes combining the sampled X-ray image data of at least one imaging frame or two or more imaging frames with at least one of the frames spanning a duration in which the exposure occurred, to produce X-ray image data capable of being reconstructed into a user-viewable image.

An X-ray imaging method includes in a digital X-ray detector including an array of discrete picture elements each including a photodiode and a transistor, applying a first voltage to the transistors of the discrete picture elements. The method also includes preparing for acquisition of X-ray image data by sampling data from the discrete picture elements while applying a second voltage to the transistors of the discrete picture elements not then being sampled, the second voltage being more negative than the first voltage. The method further includes receiving X-ray radiation on the detector from a source. The method yet further includes sampling X-ray image data from the discrete picture elements while applying the second voltage to the transistors of the discrete picture elements not then being sampled.

An X-ray imaging system includes a digital X-ray detector configured to acquire X-ray image data without communication from a source controller and to send the X-ray image data to a portable detector control device for processing and image preview. The source controller is configured to command X-ray emissions of X-rays from an X-ray radiation source for image exposures.

A method for processing X-ray image data includes exposing a digital detector to X-ray radiation. The method also includes sampling data via the digital detector including X-ray image data and offset image data. The method further includes calculating an average offset image without prior knowledge of a total number of offset image frames sampled.
