has enhanced COBRA with a
algorithm, which is more
tolerant against input data imperfections than the
standard Feldkamp method. Such data imperfections
can have any nature, e.g. absorption non-linearities
or scanner geometry misalignment (COBRA V4.0 -
under a minute, using only a PC, 2D projections can
be converted into a 512x512x512 3D image. This
software replaces current hardware- accelerated versions.
software uses the full computational power of a

be configured to run on a cluster of PC's (v.2

is implemented either as a stand-alone application
or as an SDK. In SDK mode, COBRA can start reconstruction
getting the first projection from the CT scanner.
This allows the reconstruction and data acquisition
processes to run in parallel.
