3D reconstruction system
The Barco 3D reconstruction system
Cone-beam computed tomography (CBCT) systems are capable of providing images of
high diagnostic quality, with relatively short scanning times and low radiation exposures.
CBCT systems are being adopted rapidly for imaging in the head- and neck area,
intra-operative imaging (C-arm), radiation oncology and other medical applications.
Reconstruction speed however has been a major obstacle. Barco’s 3D reconstruction
system provides a high-performance, flexible and cost-effective solution that has the
best price/performance ratio and life-cycle management in the industry.
High Precision
• Full end-to-end floating point 32-bit precision (no “hybrid” method) for true image
representation
• Error density as small as 0.5%
• Maximum Absolute Error (MaxAE) of 1HU
Real-time image reconstruction without compromising reconstruction quality
• Implements the widely used and highly efficient Feldkamp Davis Kress (FDK)
algorithm
• Real-time acquisition
• Supports asynchronous acquisition
• Reconstruction results are available immediately after the reconstruction
• Pre-weighting and filtering performed on CPU in parallel to back-projection on GPU
– taking best advantage of each processor to give the highest possible throughput
• Takes advantage of rapid GPU development improvements
Features:
• Barco high performance GPU board
• Driver optimized for medical imaging
• CT reconstruction Software
Development Kit (SDK)
• Integration services to ensure a fast
and easy integration process

A fl exible solution
• Given the highly programmable nature of a GPU solution,
it is easy to implement new algorithms and to improve
the existing ones
• GPU board can be simultaneously used for CT
reconstruction, 3D rendering and Windows visualization
• Simple scalability, by just adding more boards to the
system
• Optimized form factor solution using standard COTS
hardware
An integrated solution
• Ease of integration using easy SDK
• Supports the latest standards (OpenGL v2.0, DirectX v10.0,
PCI Express, DICOM standard for medical imaging)
