Barco MICB-1340 Specifications

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 high­performance 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
