Understanding the features
DICOM IMAGE STORAGE CAPACITY
The MetaArchive I starts with 21 TB of disk
space available to store DICOM images &
INTERNAL REDUNDANCY INDEX
This index represents the degree of internal
redundancy of a MetaArchive. An index value
of 1 means that the system will be impaired
or will stop functioning if any of its key parts
fail If key parts are replicated, or if other
methods of achieving redundancy are implemented
(e.g. RAID), then the index value increases
by a fraction of 1. If every single functional
piece is replicated and the system can immediately
switch in the spare if the primary functional
piece fails, then an index value of 2 is achieved.
EXTERNAL REDUNDANCY INDEX
This index represents the degree of external
redundancy of a MetaArchive. This index value
changes in increments of 1 (no fractions), and
correlates with the number of "hot standby"
MetaArchives that are replicating the primary
MetaArchive, and will automatically take over
operation in the event of a primary mis-function.
AUTONOMOUS SERVICE COUNT
This value represents the number of DICOM storage
services that are run when the MetaArchive comes
on line. This number is configured as a factory
default value only, and does not represents
the actual capabilities of a MetaArchive under
DICOM STORAGE & RETRIEVAL
The MetaArchive I has the ability to accept
DICOM images for storage, and to transmit DICOM
images located in its storage. The specific
DICOM 'commands' that are supported by the device
are described in the device Conformance Statement.
PATIENT, STUDY & IMAGE-LEVEL ACCESS
When using the MetaArchive I, a requestor of
DICOM images can request that the MetaArchive
identify the individual images that it has in
storage, and send individual images. Alternately,
a requestor of DICOM images can request that
the MetaArchive identify and transmit the studies
that it has in storage, where each study consists
of a grouping of images for a particular patient.
Alternately, a requestor of DICOM images can
request that the MetaArchive identify and transmit
the patients for which it has studies in storage,
where each patient can have a grouping of studies
in the store.
AUTO-PULL CAPABILITY FROM MODALITIES
The MetaArchive I can be configured to automatically
request and pull images from your modalities
for storage & distribution.
IMAGE QA AND DICOM EDITOR
The MetaArchive allows the modality technician
to accept or reject images according to their
quality to control their availability to end
users via the MetaArchive. Additionally, the
technician can use the DICOM editor to modify
header information that is missing or erroneously
populated prior to publication.
SECURE CONNECTIVITY WITH VPN
The MetaArchive has Virtual Private Network
(VPN) capability built into it. To protect against
hostile or unauthorized access to protected
information, and in order to provide security
and privacy of medical information under HIPAA,
as a standard rule, the MetaArchive I operates
in a mode where data is encapsulated & passed
over encrypted channels. VPN secure tunnels
are typically used with those networks that
have endpoints that require transmission over
non-secure or public networks, such as the internet.
Non-encrypted traffic typically is used on networks
secured by Meta Fusion.
WIRE-SPEED VPN CONNECTIVITY
Meta Fusion typically combines the MetaArchive
with external VPN hardware to add more value
to customer networks. Meta Fusion tunes the
VPN performance to match the network peformance
and the performance of the communicating devices.
In a tuned system, the data stream entering
a VPN exits the VPN at the same rate as the
input in order to ensure that the flow of information
is not slowed down by the VPN. This approach
provides a considerable performance benefit
under load as compared to a software VPN implementation.
Meta Fusion treats healthcare facilities and
their networks as inherently non-secure hostile
environments. The firewall built into each Meta
Fusion storage product is configured by Meta
Fusion to provide attack hardiness and response,
and prevent the loss or unauthorized access
to the information that we store. In the event
that the facility's network is compromised,
Meta Fusion relies on its own defenses to protect
private valuable medical information. Where
appropriate, Meta Fusion promotes the use of
its networks and its network services to healthcare
customers for implementation of networks according
to best practices and highest standards of security.
WEB ACCESS WITH SSL SECURITY
The MetaArchive comes with a built-in secure
web server. This web server is configurable,
and can be made compatible with internal firewalls.
The web server allows authorized users to connect
remotely to the MetaArchive and request DICOM
images in storage. Secure Socket Layer (SSL)
security provides the standard degree of security
in common use today.
SSL OFF-LOAD ENGINE
Server-side software SSL encryption uses up
processor cycles and time. With a 1000 users
accessing images remotely, SSL encryption can
take up a lot of time, and slow things down.
Meta Fusion provides hardware SSL implementations
as the remote user numbers grow to maintain
a high-level of system performance and a rapid
rate of image delivery.
MULTIPLE PROCESSOR ARCHITECTURE
Having multiple processors brings a number
of advantages to our designs, including performance
benefits and added fault-tolerance.
META FUSION FAULT-TOLERANT KERNEL
The Meta Fusion fault-tolerant kernel ensures
that in the event of a diaster, such as the
total loss of a susbsystem, the system will
continue to operate, without interruption, and
that it will be able to maintain this operation
as long as necessary to repair or replace the
destroyed subsystem. No human intervention is
necesary and the Meta Fusion fault-tolerant
kernel detects and compensates for faults and
failures automatically. The Meta Fusion fault-tolerant
kernel provides unique reliability benefits
for multi-hospital groups whose member hoispitals
are separated by (large) geographic distances.
Meta Fusion products are designed so that critical
systems, subsystems and functions have redundancy.
Extensive fault and failure analysis, including
ISO 14971 Fault-tree, FMEA and other methods,
are applied early on to create enduring and
Every MetaArchive has the capability of simultaneously
receiving and serving images on multiple independent
networks. The MetaArchive I is able to provide
DICOM storage & retrieval services on twelve
directly connected independent 10/100/1000 Mbit/sec
Ethernet netwokrs at one time. Meta Fusion configures
and monitors the MetaArchive device to ensure
that its presence on one or more networks does
not create security vulnerabilities on each
TRANSPORT OFF-LOAD ENGINE
The MetaArchive comes equipped with multiple
10.100 or Gigabit ethernet interfaces. It is
able to provide DICOM storage & retrieval
services on multiple directly connected independent
10/100/1000 Mbit/sec Ethernet netwokrs at one
time. With the Transport Offload Engine (TOE),
the TCP/IP protocol is implemented in firmware,
freeing up processor capacity so that the MetaArchive
can provide a high-performance service on all
of its connected networks.
Meta Fusion provides the means to use DSL instead
of T1 lines and achieve equal or higher reliability
and equal or superior bandwidth for a lower
As a component of multi-element redundancy,
Meta Fusion provides disk redundancy, including
"RAID" as a component of our fault-tolernce
DVD ARCHIVE CAPABILITY
The MetaArchive comes fitted as standard with
multiple DVD writers. This is provided for the
purposes of archiving images to a media that
can be removed to another location for further
disaster resilience. For greater convenience
and better disaster planning, Meta Fusion recommends
the use of a MetaArchive in conjunction with
A DVD jukebox typically consists of a robot
that loads and unloads DVDs from a large stack
into one or more DVD recorders, and is controlled
by a server to record information on the DVDs.
Meta Fusion provides DVD jukeboxes integrated
with some MetaArchives. Integration of a DVD
jukebox adds value to customer instances where
substantial amounts of image recording to DVDs
are desirable. These recordings may be for purposes
of archiving medical information to removable
media for redundant or off-site storage, or
to provide a means of inexpensive distribution
to patients or referrers who prefer physical
media over electronic access to images..
A large amount of additional storage capacity
may be added to a MetaArchive. Our filesystem
is well suited to storing and retrieving numerous
images. Meta Fusion recommends the use of a
MetaArchive in conjunction with your MetaArchive.
As most return visits occur within 18 months,
a MetaArchive can be sized to your facility
to provide an 18 month store, and studies may
be archived to your MetaArchive for persistence
and rapid acces over 7+ years.
A powerful rules engine is embedded into the
MetaArchive. The routing engine assures delivery
of images to where they are needed. According
to configuration of a rich set of rules, each
image that is received or transmitted by the
MetaArchive can be handled according to programmed
rules. The MetaArchive routing engine can support
a large number of end users simultanously, and
it allows for customization of rules to suit
individual users' requirements.
INTEGRATED WORKFLOW ENGINE
Meta Fusion provides a rule-based configurable
mechanism to assist in managing your imaging
department workflow, including communications
and prompts to ensure that members of your team
respond timely and keep close track of patients
and their tasks.
From an end-user point of view, each MetaArchive
is intended to be operated as a zero-maintenance
appliance. The management of the device is performed
remotely in most cases.
SELF-DIAGNOSIS & CERTIFICATION
The MetaArchive continuously performs self-checks
to ensure correct operation & reports anticipated
and actual problems. Each MetaArchive can also
be tied to Meta Fusion's operations infrastructure
whereby it is continuously monitored by external
agents that report on its health, correct function,
regulatory compliance and raise alarms to initiate
rapid response in the event of actual or anticipated
The MetaArchive supports a 'transparent mode'
that allows an auditor process to evaluate the
HIPAA compliance of the device as it operates,
and according to the device operation logs.
The verified HIPAA audit report is securely
As standard, the MetaArchive keeps detailed
logs of its operation, including tracking every
image access and attempts to access images.
These logs are saved, and offloaded for signing
by Meta Fusion.
Each MetaArchive provides built-in storage
management rules that may be activated or de-activated
under suthorized user control. These storage
rules provide for immediate or delayed storage
ageing, clean-up and optimization. When automatic
ageing criteria are configured, the MetaArchive
can perform its functions for extended periods
of time without requiring any administration.
ACCESS CONTROL LISTS
MetaArchive strictly controls access by users
according to a list of authorized entities.
Users that are not on the access control list
are denied access to the MetaArchive.
Meta Fusion provides a mechanism to add compression
to your image transfer and storage in a MetaArchive.
The compression may be switched on and off.
Reversible and irreversible compression are
COMPRESSION OFF-LOAD ENGINE
By allocating separate resources to performing
compression and de-compression tasks, the system
performance can be maintained at a high-level
METERING OF STUDIES
The MetaArchive can track the number of individual
accesses by end users to patient studies, and
provide a verified report of these accesses
upon demand. This feature is very useful for
DICTATION & TRANSCRIPT STORE
The MetaArchive provides a dictation &
transcript store with association to the patient
study that is the subject of the diagnosis.
Dictation files and diagnosis transcripts can
be uploaded to the MetaArchive automatically
by means of a secure web interface.
The MetaArchive provides an HL-7 interface
capability by means of which a RIS or a HIS
or other information system may be integrated
with the MetaArchive.
METAFUSION MCDP PROTOCOL
Meta Fusion Collaborative Diagnosis Protocol
METAFUSION MDSIP PROTOCOL
Meta Fusion Server Interaction Protocol (MDSIP)
is used to provide seamless integration when
many hospitals each with one or more MetaArchives
combine to provide continuity of care and access
to patient historical records independently
of geographic location.
