COBRA software development kit. Integration COBRA into customer’s software.Recommended PC We recommend the following PC giving the best price/performance ratio COBRA speed for the basic CT reconstruction task Lets assume that the used PC is what is recommended above. Lets also assume that our scanner is built corresponding a classic Felfkamp scheme (symmetric detector setup); input projections (views) are 512x512 and our CT scan contains 512 input views. All projections are located on the hard disk. Then it takes approximately 15 seconds to get a reconstructed volume 512x512x512 in RAM and additional 5-8 seconds to save the volume to the disk. Performing on various hardware platforms PC with a graphics card. For cards with a decent number of processing units (192 and up) and a decent size of built-in RAM (768 MB and up) a reconstruction speed may vary from 52 msec per view with 8800GTX to 25 msec per view with GTX480. All numbers in this section are relevant for the basic CT reconstruction task (512x512x512 → 512x512x512). Dependence on geometry setup and corrections The reconstruction speed dramatically depends on input/output data and applied corrections. The following approximate rules may be taken into account Examples PC: Intel quad-core i7 / 2.4 GHz / Geforce GTX480 360 input views 512x512 → 512x512x512 volume: 768 input views 1024x1024 → 1024x1024x1024 volume: 3-4 min total time. 5x1024 input views (5 stacked volumes) |
