An X-ray imaging device includes a color sensor configured to generate a color signal indicating a particular color sensed, an imaging matrix of pixel detector elements that are each configured to detect photon energy and generate an image signal, and a controller that is coupled to the color sensor, the imaging matrix, and the wireless transceiver. The controller is configured to receive a color signal from the color sensor, determine an identifier of the computing device external to the X-ray imaging device based on the color signal, and change at least one operational setting of the X-ray imaging device based on the identifier.
RADIOGRAPHIC IMAGE PROCESSING APPARATUS, RADIOGRAPHIC IMAGE PROCESSING METHOD, AND RADIOGRAPHIC IMAGE PROCESSING PROGRAM
An image acquisition unit acquires first and second radiographic images acquired by irradiating a first radiation detector and a second radiation detector which overlaps the first radiation detector so as to deviate from the first radiation detector by a half pixel with radiation which has been emitted from a radiation source and transmitted through an object. A corresponding positional relationship acquisition unit acquires a corresponding positional relationship between the position of pixels of the first radiographic image and the position of pixels of the second radiographic image. A resolution enhancement unit estimates a pixel value corresponding to a position between the pixels of the first radiographic image, on the basis of the corresponding positional relationship, a pixel value of the first radiographic image, and a pixel value of the second radiographic image, and generates a processed radiographic image having a higher resolution than the first and second radiographic images.
Image quality in computed tomography using redundant information in production data sets
A method is provided for detecting a movement of a body between acquisition times of at least two acquisition data sets, wherein, for virtual sectional planes of the body, a first intermediate function value of attenuation values of all the body elements lying in the sectional plane is determined based on a first acquisition data set, and a second intermediate function value of the attenuation values is determined based on a second acquisition data set. For each sectional plane, a difference value is determined from the intermediate function values. A total error value for the two acquisition data sets is calculated by combining the difference values of all the sectional planes. The virtual sectional planes have a common line of intersection, and for the particular acquisition time, the difference between pairs of the sectional lines is at least one pixel.
Luggage visualization and virtual unpacking
Methods and systems for luggage visualization perform virtual unpacking by visually moving an object image away from its original pose. A scanned 3D volume is segmented guided by a confidence measure to create a label volume whose voxels specify the detected object IDs. The luggage dataset and the label volume are visualized by volume rendering. Using an automatic coloring algorithm, any pair of objects whose projections are adjacent in an image are assigned distinct hues. A layered framework efficiently renders a scene mixed with packed luggage, animated unpacking objects, and already unpacked objects put aside for further inspection. A GPU is used to automatically select objects that are not blocked by others and can be unpacked.
