A novel algorithm is presented to segment and reconstruct injected bone cement from a sparse set of X-Ray images acquired at arbitrary poses. The Sparse X-Ray Multi-view Active Contour (SxMAC – pronounced “smack”) can (1) reconstruct objects for which the background partially occludes the object in X-Ray images, (2) use X-Ray images acquired on a non-circular trajectory, and (3) incorporate pri...
X-ray scattering images contain numerous gaps and defects arising from detector limitations and experimental configuration. We present a method to heal X-ray scattering images, filling gaps in the data and removing defects in a physically meaningful manner. Unlike generic inpainting methods, this method is closely tuned to the expected structure of reciprocal-space data. In particular, we explo...
This paper presents a method for applying a computer-aided diagnosis (CAD) for pneumoconiosis to chest X-ray images digitalized by the computed radiography (CR) system. When we reported the CAD before, we showed performance of the CAD for chest X-ray images digitalized by a CCD scanner. However, since density distribution of the CR X-ray images is quite different from the images digitalized by ...
The ongoing FP7 project “ACXIS Automated Comparison of X-ray Images for cargo Scanning” delivers enhanced inspection procedures for customs. A manufacturer independent reference data base for X-ray images of illegal and legitimate cargo is developed. One of the X-ray image recording work flow is to use 3D-CT data of illegal cargo mockups and to artificially generate arbitrary X-ray projections....
3D reconstructions allow cultural institutions such as museums and historic sites a tool to vividly illustrate the past while educating the public about competing interpretations of history and change over time. 3D technology also offers many practical benefits including low cost, flexibility, and the potential for collaboration. This paper presents potential applications of 3D reconstructions ...
