Abstract: A system for generating a 4D representation of a scene in motion given a sinogram collected from the scene while in motion. The system generates, based on scene parameters, an initial 3D representation of the scene indicating linear attenuation coefficients (LACs) of voxels of the scene. The system generates, based on motion parameters, a 4D motion field indicating motion of the scene. The system generates, based on the initial 3D representation and the 4D motion field, a 4D representation of the scene that is a sequence of 3D representations having LACs. The system generates a synthesized sinogram of the scene from the generated 4D representation. The system adjusts the scene parameters and the motion parameters based on differences between the collected sinogram and the synthesized sinogram. The processing is repeated until the differences satisfy a termination criterion.

Abstract: An arena test system for characterizing fragments from a warhead. An entry panel and an exit panel are arranged in a wedge configuration with a wedge-shaped air space between them. Fragments are imaged as they pass through this wedge. A soft catch box is located behind the exit panel such that fragments that pass through the exit panel enter the soft catch box and are decelerated within the soft catch box.

Abstract: An object is to enable a suitable image conforming to the movement of an imaging target to be captured. A motion detection device provided on an imaging target side (person or movement object) detects the motion of the imaging target, which is transmitted as motion information. An imaging apparatus receives the motion information detected by the motion detection device, predicts the motion of the imaging target based on the motion information, changes imaging settings based on the predicted motion of the imaging target and controls imaging function based on the imaging settings.

Abstract: Provided is an in vivo movement tracking apparatus configured to track a portion of interest that moves in vivo, in which accuracy and robustness of tracking are improved. The apparatus is configured to determine an estimated position of ah organ in a biological image based on the past movement of the organ and search for contour points corresponding to a plurality of control points, respectively, representing a contour shape of the organ in a region corresponding to the estimated position, to thereby determine an estimated contour of the organ based on the contour points. The in vivo movement tracking apparatus is configured to determine a position of a portion of interest, which moves in association with the organ, based on the estimated contour with reference to previously acquired sample data regarding a positional relationship between a contour of the organ and the portion of interest.
