The Medical Informatics Group, the current IT infrastructure serving the Department of Radiology, consists of a high-speed corporate network interconnecting the multi-site Health System and multiple enterprise-wide information systems:

  • Electronic Master Patient Index (EMPI),
  • Radiology Information System (RIS),
  • Voice Recognition (VR) dictation system, and
  • Picture Archival and Communication System (PACS).

The projected PACS network will connect 200 imaging modalities spanning over four hospitals and several imaging clinics. Combined workload is around 700,000 patients per year generating 25-30 TB of new (uncompressed) imaging data per year. The PACS architecture is hybrid with a central, high-throughput, redundant DICOM archive (with 275 TB online) and distributed RAID servers (6 TB Storage Area Networks) for immediate delivery of recently acquired images, associated priors, and reports. The entire system is serviced by Siemens Medical Systems (Malvern, PA) under an integrated 8-year operational service contract. The imaging network and archives are fully compliant with the latest HIPAA requirements providing password protection, 128-bit encryption, access controls, and audit trail capabilities. The multi-layer corporate firewall and Virtual Private Network (VPN) circuits provide additional safeguards.

In addition to the above mentioned infrastructure, we are also pursuing groundbreaking research in the radiology informatics field. This includes studies and research on film-based vs. filmless radiology, probabilistic medical records linkage across non-affiliated institutions, data migration schemes, data mining strategies, structured reporting, computer-aided diagnostics, and image processing. We are also involved in the design and implementation of patient-centric electronic medical records, diagnostic workstations, utilization of digital displays (PACS) in the OR suites, and web-based distribution of images and reports to the entire Health System.
