  This paper focuses on minimizing the time requirement for CT capture through
innovative simultaneous x-ray capture method. The state-of-the-art CT imaging
methodology captures a sequence of projections during which the internal organ
movements may lead to poor reconstruction due to motion artefacts. Traditional
CT scanners' minimize such effect by taking more projections than necessary. In
this work we focus on an innovative CT capture method that captures projections
simultaneously, promising super fast scans along with possible radiation dose
reductions. While the simultaneous CT capture model has already been proposed
in our earlier work 'Multi-axial CT Reconstruction from Few View Projections'
(in SPIE Optical Engineering and Applications, pp. 85000A-85000A. International
Society for Optics and Photonics, 2012) and 'A New Imaging Method for Real-time
3D X-ray Reconstruction' (in SPIE Medical Imaging, pp. 86685G-86685G.
International Society for Optics and Photonics, 2013), in this work we enhance
the model through better initialization along with prior smoothing before
successive iterations of the iterative algorithms. We also elaborate the model
considering different X-ray source/detector configurations. Results show that
it is possible reconstruct a cross-section slice by considering only four
angular projections. With eight projections, the reconstruction is further
improved. The main promising matter about this method is that, all these
projections (i.e. four or eight) can in principle be captured simultaneously,
implying CT capture in one go just like a chest X-ray.
