An object oriented fully 3D tomography visual toolkit

In this paper we present a modern object oriented component object model (C OM) C++ toolkit dedicated to fully 3D cone-beam tomography. The toolkit all ows the display and visual manipulation of analytical phantoms, projection sets and volumetric data through a standard Windows graphical user interfac e. Data input/output is performed using proprietary file formats but import /export of industry standard file formats, including raw binary, Windows bi tmap and AVI, ACR/NEMA DICOM 3 and NCSA HDF is available. At the time of wr iting built-in implemented data manipulators include a basic phantom ray-tr acer and a Matrox Genesis frame grabbing facility. A COM plug-in interface is provided for user-defined custom backprojector algorithms: a simple Feld kamp ActiveX control, including source code, is provided as an example. our fast Feldkamp plug-in is also available.
