System speeds up CT reconstructions
During ECR 2008, the Canada-based Acceleware Corporation, which develops acceleration solutions for high-performance computing, demonstrated its new AxRecon image reconstruction solution for medical imaging, security, and non-destructive testing.

‘Image reconstruction for computed tomography (CT) scanners often takes hours of processing time and represents a major barrier to efficiency for many organisations. Acceleware’s solution reduces the time required to complete this work from hours to minutes,’ the firm reported. ‘AxRecon works with existing cone beam CT scanners to eliminate bottlenecks by significantly speeding up filtered back projection computations. This enables medical and commercial users to accelerate the reconstruction of their data and improve the quality of their images without disrupting their current workflow.’
AxRecon combines Acceleware’s proprietary software acceleration libraries with the massive parallel processing power of NVIDIA Graphic Processing Units (GPUs).
David Holdsworth of Robarts Imaging, based in Canada, added: ‘In biomedical micro-computed tomography applications, the volume dimensions of our reconstructions have increased dramatically over the past few years. During the same period, scan times have also been reduced; this makes cone-beam CT reconstruction time the bottleneck that limits workflow in some situations. GPU-based reconstruction is a cost-effective solution for this task, and we have found that Acceleware’s AxRecon product can provide 3-D reconstructions up to 50 times faster than a single-CPU.’
Acceleware also emphasised that the software seamlessly integrates with existing CT scanners with minimal setup.
Sean Krakiwsky, CEO of Acceleware, added: ‘The benefits of higher throughput and image quality already being realised by early customers of AxRecon will help us drive adoption of this product within the broader imaging market.’
