Barco MICB-1340 User manual

MICB-1340
The MICB-1340 is a high-performance PCI-e based compression board optimized
for medical imaging applications. Installed on a server, it compresses images to
stream them efficiently across a network within a client-server or remote computing
environment.
By relieving the main CPU from the compression task, the MICB-1340 allows for
compact, cost-effective yet high-performance image server systems.
The MICB-1340 performs both lossless and lossy image compression for a large
number of simultaneous users. This allows for high-quality image streaming to wired
or wireless clients in demanding healthcare environments.

New scenario: using Barco's MICB-1340 compression board
Compress your images
Impress with performance
The quick adoption of MDCT, volumetric images and time-series studies has led to
an exponential growth of image data sets in medical imaging. Simultaneously, the
advent of networked EMR systems creates a pull for images from connected devices
across the enterprise. This evolution puts a heavy burden on the hospital’s network
infrastructure and budget.
To overcome the problems associated with large data sets, more and more hospitals
opt for a solution based on central rendering and image streaming over the
network.
Typical scenario: image streaming across a network
Plugged into the rendering server, Barco's MICB-1340 compression board takes over
the compression task from the CPU. This allows for a compact, cost-effective yet high-
performance image server system. The advanced MICB-1340 performs both lossless
and lossy image compression for a large number of simultaneous users.

Problem 1:
Medical images take up a lot of network bandwidth.
This results in bad or unstable image quality.
Problem 2:
Good compression kills CPU performance.
While the CPU is occupied with compression tasks, it does a bad job handling
medical applications such as rendering, segmentation, reconstruction, ...
Disadvantages of compression in software (CPU):
• Very high processor load
• No real-time compression possible
• Compromise between good compression or low CPU load
• High power consumption per client
Benefit 1:
High-performance imaging on any network.
Benefit 2:
CPU load remains low.

A practical example
A server is running a medical 3D application, sending bitmaps to 18 remote clients
across the enterprise. To allow for optimum network performance, the bitmaps are
being compressed.
• Scenario 1: compression is performed by the CPU
• Scenario 2: compression is performed by the MICB-1340 board
Technical specifi cations
Format: standard PCI-e x8 board
Codec: lossless: based on JPEG-LS (ISO/IEC 14495/1)
lossy: based on JPEG
Performance: maximum throughput of 1200 MB/s
Power consumption: 20 W at full power
Typical setup that 1 board can handle:
• 15 simultaneous users at 1600 x 1200 x 24 bit/pixel
• frame rate: 25 Hz
• 75% of image updated
• 75% of users active
Deliverables: • PCI-e board
• Linux driver (kernel 2.6.x)
• Linux application library
• Windows® driver (XP 32/64, Vista)
• Windows® application library
• Sample application incl. source
