microCT 100High-resolution microCT imaging produces large amounts of data, as shown clearly in the example on the right. This whole-body measurement of a rat was made using a vivaCT 75 and comprises 7800 images with a matrix size of 2048x2048 and 2 bytes per voxel, giving a total size of 65 GB.

To enable 3D analysis of such large data sets, SCANCO Medical microCT systems are supplied with powerful Itanium2-based, 64-bit HP Integrity servers running OpenVMS. This highly stable, multitasking platform allows measurement, reconstruction, analysis and archiving to be performed simultaneously.

The exact computer configuration is customized to best suit your requirements, and systems can be expanded easily with additional computers. Computers are configured to your environment (network configuration, printer setup, account setup etc.) and carry HP's three-year worldwide hardware warranty.

For more computing power, multiple computers can be clustered for automatic workload distribution and to provide multiple workplaces.

Disk storage

Storage capacity can be expanded by adding external hard disk towers to your microCT system. Particularly attractive is the addition of disk towers configured with RAID 6 disk arrays, which store your data on multiple disks automatically, helping to protect you from data loss. Hot spare disks can be included for extra peace of mind.

D3600 SAS 7'200 80 TB (12 x 8 TB) (2/RAID 6)

SAS disks are recommended for highest performance.

A maximum of 5 D3600 arrays can be connected in cascade per RAID controller. HPE disk towers carry a one (SATA, midline SAS) or three-year guarantee (SAS enterprise) with next working day exchange in the event of disk failure.

Tape archiving

The large size of microCT data sets makes it impractical to store all data on disk at all time. To address this issue SCANCO Medical supplies LTO-format Ultrium magnetic tape drives for archiving data as part of an integrated data managementconcept. This magnetic tape-based approach allows unlimited expansion of data storage capacity.

Media in the industry-standard LTO format are manufactured by many leading companies, including HPE, Sony and Imation, and are readily available from good computer suppliers. (Note that the advertised capacity of tape media is based on data storage using 50% compression. MicroCT data does not allow such high compression, so effective media storage capacity for archiving is down to half the advertised value.)


SCANCO Medical uses OpenVMS, a highly reliable, multitasking, real-time operating system that provides integrated, proven support for clustering. In an OpenVMS cluster multiple computers connected via Ethernet share resources such as processors and disks to balance workload.

For microCT systems, clustering ensures that reconstruction and 3D analysis tasks are distributed automatically among several computers, avoiding bottlenecks where a single computer is overloaded while others are idle. From a user's perspective the cluster is invisible: interactive tasks can be performed at any clustered computer.

OpenVMS's clustering capability protects your investment in computing hardware for your microCT system. New and old computers are combined to form a single cluster, seamlessly expanding your data analysis capacity.
