SkyScan cluster volumetric reconstruction

Standard NRecon, starting from ver.1.6 supports reconstruction by both NReconServer and InstaRecon® reconstruction engines using an identical user interface. For best performance of InstaRecon® reconstruction, the recommended PC configuration includes 32GB memory and two hard drives on a RAID0 array. The InstaRecon® reconstruction engine is available as an option with new SkyScan scanners, as well as as an upgrade to existing installations. A single computer version of the InstaRecon® reconstruction engine runs up to 8 threads (dual-Quad core), a cluster version runs up to 32 threads (four PCs with dual-Quad-core processors). Both versions can reconstruct datasets from any SkyScan scanner up to 8Kx8K pixels in cross section. The SkyScan's NRecon/NreconServer reconstruction software continues to be delivered for free with all SkyScan instruments. Demo versions of InstaRecon® reconstruction engine are available for one month free evaluation (require continuous internet connection).

SkyScan's volumetric reconstruction software "Nrecon" uses the set of acquired angular projections to create a set of cross section slices through the object. The program uses a modified Feldkamp algorithm with automatic adaptation to the scan geometry in each micro-CT scanner. Reconstructed slices can be saved in BMP, TIFF, JPG or numerical data format. The program can run on one PC or distribute the reconstruction across a cluster of several networked PCs working in parallel to achieve exceptional speed. Nrecon measures and adapts to differences in computer performance and network connection for equitable job distribution. Reconstruction includes beam-hardening correction, alignment optimization, ring artifact correction, reconstruction in a restricted volume of interest, reconstruction of objects wider than the field of view, external and internal calibration into Hounsfield units and interactive density window selection.

Nrecon accepts large format angular projection images to reconstruct cross section images with up to 8000x8000 pixels. User-friendly batch processing allows many reconstruction jobs with different settings to be run sequentially without operator input.

Reconstruction and visualization programs <<< other direct links here		SkyScan supplies all micro-CT scanners with high-speed volumetric reconstruction software, which can be optionally accelerated by a cluster of several computers connected by a gigabit network. The results of 3D reconstruction can be displayed by slice-by-slice scrolling, by three orthogonal sections through any internal point of the reconstructed space, or by conversion to realistic 3D models.
		BREAKING THE SPEED BARRIER: SkyScan starts to supply the InstaRecon® reconstruction engine - world's fastest reconstruction based on new patented algorithms. The new reconstruction software can run on any PC or cluster of up to four PCs under 32 and 64-bit Windows XP / Vista operation systems. Depending on the size of the cross sections, it provides speed-up x10 to >x50 compared to the fastest currently available software and x2...x10 compared to reconstructors using graphical processors (GPU). The InstaRecon® reconstruction engine runs on standard PCs without involving any special hardware or GPU.

		VISUALIZATION, FORMAT CONVERSION The reconstructed set of slices can be flexibly viewed in SkyScan's "Data Viewer" program. Images are displayed as a slice-by-slice movie or as three orthogonal sections, centered at any selected point inside the reconstructed space. Data Viewer also has a viewing mode with three intersecting orthogonal sections, which can be turned and each intersecting slice independently moved by simple mouse control. Additional features include variable smoothing, saving interpolated datasets in saggital or coronal section, measuring and saving distances and intensity profiles. The format converter utility "T-conv" converts between TIFF, BMP and JPEG files with adjustment of colour palette, inversion, renaming, resizing and combining of datasets. A utility is also provided for conversion to DICOM 3 format.
