Embodiment Construction

[0037] The following follows a detailed description of the preferred embodiment of the invention, reference being made to the accompanying drawings, in which like reference numerals identify like elements of structure in each of the several views.

[0038] FIG. 1A shows a conventional x-ray imaging system 10 that provides images on removable media, such as removable film or CR cassettes 16 . An operator console 12 is located in a control room 14, shown below the dashed line in FIG. 1A and subsequent figures. An x-ray generator 22 is installed in the radiation chamber 20, shown above the dashed line. Cassette 16 is placed behind patient 18 for obtaining images. Exposure energy is provided by an x-ray tube 24 controlled from an x-ray generator 22 . Not shown but widely used in conventional devices are also exposure control devices, such as automatic exposure control (AEC) devices, which measure exposure levels and terminate exposure when a target radiation level has been reach...

Abstract

A method and apparatus are disclosed for obtaining an x-ray image from an x-ray imaging apparatus using a digital radiography receiver installs a retrofit connection apparatus that adapts the x-ray imaging apparatus for use with the digital radiography receiver by forming a receiver interface channel for communicating signals to and from the digital radiography receiver, forming an operator interface channel for routing at least an input expose signal from an operator control to the connection apparatus and forming a generator interface channel for transmitting at least an output expose signal from the retrofit connection apparatus to an x-ray generator of the x-ray imaging apparatus. An input expose signal over the operator interface channel initiates a reset of the digital radiography receiver over the receiver interface channel before the output expose signal to the x-ray generator is transmitted over the generator interface channel.

Description

technical field [0001] The present invention relates generally to digital x-ray imaging and more particularly to methods for adapting conventional film-based and / or computed radiography (CR) x-ray imaging systems for use with improved digital radiography (DR) detectors. Apparatus and methods. Background technique [0002] DR is an alternative to x-ray imaging techniques that rely on photosensitive film layers to capture radiation exposure and thus to produce and store images of the internal physical features of objects. Using digital radiography, the radiation exposure energy captured on the radiation-sensitive layer of a digital x-ray detector is converted pixel-by-pixel into electronic image data, which is then stored in memory circuitry for subsequent readout and display on a suitable electronic image display device. One of the driving forces behind the success of digital radiography is the ability to rapidly visualize and transmit stored images over a data network to o...
