Campus Description
  • Medical Center (GUMC)
  • 8 Research Buildings
  • Main Campus
  • 32 Campus Buildings including Dorms,Staff and
    Academic
  • 6 Ancillary Buildings connected via 100Mbps

3
GUMC Network
  • Gigabit Core
  • Building Distribution Frames (BDFs) have a Dual
    Gigabit connection to the core
  • Floor Switches have a Gigabit connection to the
    BDFs
  • User provided with 10/100 connection

5
Main Campus Network
  • OC-12 ATM core
  • Server Farm has OC-12 connections to the core
  • BDFs have dual OC-3 connections to the core
  • Floor Switches have 100-200Mbps links to the BDFs
  • User provided with 10 or 10/100 connection

7
Remote Site Connections
  • OC-3 ATM
  • Frame-Relay
  • FNS (10Mbps)
  • T-1

8
Internet 2
  • Connected via ATM utilizing Unspecified Bit Rate
    (UBR)
  • Primary connection to Abilene through MAX
  • Currently being used to test teleradiology
    application in the study of ALD

9
What is ALD?
  • Adrenoleukodystrophy is a rare genetic disorder
    that is often fatal in young boys.
  • It affects 1 in 20,000 people world-wide
  • A neurological disorder that destroys the myelin
    in the brain
  • Myelin insulates nerves and allows conduction of
    impulses between parts of the body
  • MRI permits early detection of nervous system
    damage and is a sensitive indicator of disease
    progression

10
Why are Multi-Center Clinical Trials Needed
  • No institution has enough patients to perform a
    randomized control study
  • ALD trained physicians are few due to the rarity
    of disease
  • Sharing of film images is difficult in an
    analogue world

11
Solution Digital ALD MRI Network
  • Multiple sites can send data to a centralized
    database
  • Consolidation of data provides sufficient patient
    pool for therapy evaluation
  • ALD trained physicians have immediate remote
    access to the exams

12
Project Description
  • Development of DICOM network
  • DICOM database resides at KKI
  • Receives MRI studies from multiple institutions
    in US and world-wide
  • Permits query/retrieve of studies by ALD trained
    physicians for review
  • Utilizes secure technologies to ensure patient
    confidentiality and data integrity
  • Works over standard Internet and NGI

13
UMN ISIS KKI
  • Requested data from UMN over NGI
  • Upon receipt, immediately sent it to KKI over
    standard Internet
  • Recorded transmission times
  • Ran the test 7 times
  • Results
  • ISIS UMN averaged 242.5 seconds
  • ISIS KKI averaged 2062.2 seconds

14
Transmission Time UMN ISIS KKI(Seconds)
ISIS KKI 45 miles
UMN ISIS 1100 miles
15
ISIS KKI
  • Requested studies from KKI DICOM server to ISIS
  • Ran the test 78 times over standard Internet
  • Ran the test 83 times over NGI

16
Throughput Internet vs. NGI
17
Results
  • Moving digital images is better than using film
    for sharing information
  • Standard Internet is unpredictable for moving
    large data sets
  • NGI supports real-time teleradiology
  • Future enhancements of the NGI will be evaluated

18
Current Projects at GU
  • Wireless Testing with authentication to LDAP
  • VoIP
  • Multicasting
  • QOS
  • Gigabit Connection to the Internet

  • Thanks to Betty Levine and MaryLou Ingeholm in
    ISIS for ALD testing info
