A visual indication is generated of depth locations of slices obtained by applying a reconstruction algorithm in a computed tomography method with given settings, the display being shown on the object, e.g. on the patient's lateral side or in close relation to the patient.

A method for triggering image capture by a group of simultaneously X-ray exposed multiple wirelessly interlinked self-triggering direct radiography (DR) detector assemblies includes the steps of performing an initiation step to identify the group of participating DR detector assemblies prior to X-ray exposure, detecting the X-ray exposure by a first participating DR detector assembly, the first participating DR detector assembly performing a trigger step to signal all participating DR detector assemblies to start image capture.

Method for controlling multiple wireless self-triggering radiographic image sensors in a single exposure

A method controls for a planned radiographic exposure the spatial position of a portable digital direct x-ray detector in a medical imaging system including multiple radiographic exposure stands. The method includes creating a three-dimensional spatial model of the medical imaging system, determining within the model the spatial position of the detector based on input received from three gravity sensors installed thereon, determining a three-dimensional volume space for each radiographic exposure stand, and checking whether the spatial position of the detector fits within the three-dimensional volume space of the radiographic exposure stand.

A method includes selecting, in a radiographic exposure unit, a direct radiographic panel as an active panel for a forthcoming radiographic exposure, activating a gravity sensor installed on the direct radiographic panel, and activating by the activated gravity sensor a processor installed on the direct radiographic panel. As a result of a communication from the processor with a radiographic work station over a network, the activated direct radiographic panel is retained as the active direct radiographic panel for the forthcoming radiographic exposure.

A method for the determination of the delay time of a radiographic generator and to the setting of a standard value for such delay time. According to the method it is determined by a series of decreasing chosen values for the delay time whether a signal for the confirmation of the start of the radiographic exposure is rendered by the radiographic generator. The last value of the chosen delay time whereby still such a confirmation signal is rendered, is retained as standard operational value for the delay time of the radiographic system.

Method of associating meta-data relating to a radiation image of an object with the radiation image wherein the meta-data are broadcast and are detected and associated with an activated radiation image recording device.

Method of associating meta-data of radiation image with image

Each of the detectors of a detector inventory are subjected to an identical flat field exposure to generate a radiation mage in each of the detectors, from the radiation images the overall field distribution is determined and neutralized in the images, next the sensitivity is determined.

Method of determining sensitivity of radiation detector

Each of the detectors of the inventory are subjected to an identical flat field exposure to generate a radiation mage in each of the detectors, from the radiation images the overall field distribution is determined and neutralized in the images, next the non-uniformity is calculated.

Method of determining non-uniformity of detector inventory

A first time stamp Tindicative of the time of irradiation of an object and a second time stamp Tindicative of the time of exposure of an image detector by the radiation image of the object, are generated. Meta-data relating to the object are associated with the radiation image of the object if Tequals Tor if Tapproximates Twithin a predefined limit.
