Summary / Description

Summary / Description

The MAS combines IBM Tivoli software and TotalStorage technologies to manage and access medical images Solutions based on specific storage policies in an environment rich in security features. The MAS is pre-built and configured to address medical imaging storage requirements, and is designed for near- and long-term access and archival of Picture Archive Communication Systems (PACS) and other image related data. The MAS was designed to integrate easily behind the DICOM Archive components of PACS solutions.

Excerpt

Excerpt

When exams are moved into the MAS, the Tivoli Storage Manager software manages the images based on a preconfigured policy. While the policy can be customized for each organization, in most cases, Tivoli Storage Manager will handle exam migration to storage pools and back-up copies for disaster recovery. Tivoli Storage Manager also implements an “aging” policy for all exams, migrating data to lower cost online and near-line storage as studies get older. It is the “aging” capability of the MAS that facilitates the optimal use of tiered storage within medical imaging archives. Exams initially moved to the MAS will likely demand fast retrieval and will be stored on SAN Fiber Channel (FC) disk storage in RAID5 arrays. After a period of time, the likelihood of an exam being retrieved decreases significantly, and the exam is relocated to lower-cost storage. With the addition of Serial ATA (SATA) technology, however, these studies can remain on very fast, spinning storage for longer periods of time, which should lessen the impact to study retrieval performance. In a typical IBM MAS install, clients acquire sufficient FC and SATA storage to support three years of exams. After three years, the study will migrate to the tape library unless more SATA storage is added. If the exam is allowed to migrate to tape, it remains addressable and eligible for pre-fetch or ad-hoc requests, but with retrieval measured in minutes instead of seconds.

Claims

A method for dynamic, two-stage clinical data archiving, said method comprising:copying clinical data from a primary datastore to a staging datastore, wherein non-clinical data is retained at the primary datastore and not passed to the staging datastore;

copying the clinical data from the staging datastore to an archive datastore; and

deleting the clinical data from the staging datastore after the clinical data has been copied to the archive datastore.

Relevance

Claim Chart

All

A dynamic, two-stage clinical data archiving and restoration system, said system comprising:a primary datastore storing clinical data, demographic data and application-specific data for a patient;

an archive datastore archiving clinical data from the primary datastore for later retrieval;

a staging datastore storing and relaying clinical data between the primary datastore and the archive datastore, the staging datastore retaining the clinical data until at least one of an archive operation and a restore operation is complete between the primary datastore and the archive datastore; and

a processor operating in conjunction with the primary datastore, the staging datastore, and the archive datastore, the processor adapted to archive clinical data by:copying clinical data from the primary datastore to the staging datastore, wherein non-clinical data is retained at the primary datastore and not passed to the staging datastore;

copying the clinical data from the staging datastore to the archive datastore; and

deleting the clinical data from the staging datastore after the clinical data has been copied to the archive datastore.

Relevance

Claim Chart

Some

The system of Claim 12, wherein the processor facilitates searching of clinical data stored at the archive datastore without restoring the clinical data to the primary datastore.

All

The system of Claim 12, wherein the processor provides access by a user to archived data at the archive datastore.

Relevance

See Claim 6.

Claim Chart

All

A computer readable medium having a set of instructions for execution on a computer, said set of instructions comprising:an archive routine controlling a primary datastore, a staging datastore, and an archive datastore, wherein the archive routine:a) copies clinical data from the primary datastore to the staging datastore, wherein non-clinical data is retained at the primary datastore and not passed to the staging datastore,

b) copies the clinical data from the staging datastore to an archive datastore, and

c) deletes the clinical data from the staging datastore after the clinical data has been copied to the archive datastore; and

a restore routine controlling the primary datastore, the staging datastore, and the archive datastore, wherein the restore routine:a) identifies clinical data to be restored from the archive datastore,

b) copies the identified clinical data from the archive datastore to the staging datastore,

c) copies the identified clinical data from the staging datastore to the primary datastore, and

d) deletes the identified clinical data from the staging datastore.
