Film Digitizer

The Scanning Workbench from BRIT Systems is a high quality film digitization system for both PACS and teleradiology applications. The system is a DICOM Storage SCU: it transmits DICOM secondary capture images using a selection of transfer syntaxes (different DICOM compression algorithms). It also supports DICOM modality worklist and print clients, includes a DICOM viewer and supports an HL-7 interface. Used with a DICOM printer, the system can also be used as a film copier, providing superior copies than those produced by conventional methods. The same PC controller can also be used to run BRIT's Capture Workbench, which is a frame grab solution and a DICOM Storage SCP. By combining The Scanning and Capture Workbenches, a single computer and network connection can be used to transmit film, frame grabbed (DICOM secondary capture) images and DICOM images in a teleradiology application.

Each Scanning Workbench combines:

  • Either a laser or CCD film digitizer
  • A Windows NT based controller and front-end to the scanner
  • A network connection: 10/100 Ethernet for local area networks; modems or ISDN for dial connections; modems, ISDN, xDSL or cable modems for use with Internet/VPN connections
  • Optional multi-sheet feeder
  • Optional barcode reader
Scanning Workbench Hardware

All models of The Scanning Workbench meet the ACR guidelines for primary diagnosis. Models configured with the Lumiscan 85 produce images with resolution of 10 lp/mm (the produced images are viewable on any of BRIT's viewers), recommended for mammography research projects. The optional film feeder should be considered for heavy workloads. A special software /hardware configuration is available for heavy archival use that utilizes barcode readers, the HL-7 interface, barcode printers and large capacity film feeders.

Patients are entered into the system via the modality worklist, typing or optionally via a barcode interfaced with an information system. Configurable pull-down menus provide consistent exam descriptions while increasing efficiency. Additional exams can easily be added for the same patient. A selection of scanning resolutions and compression ratios is available. The receiving locations are selectable for each exam. Additionally, if a receiving location is always the same, such as an archive, exams can automatically be sent there. For applications utilizing the Internet, a VPN (Virtual Private Network) can be deployed to meet HIPAA regulations. The system also includes a server that users can access and download exams.

After the images have been scanned, an optional QA screen is presented. Using the QA process, the technologists can manipulate the image by flipping or rotating or running different processing algorithms. They can also reject an image or re-digitize a film.

All Scanning Workbenches come with a copy of BRIT's Clinical Workbench medical image viewer.
