Controlled Quality Wavelet Compression™ Images-on-Call Software Drivers DICOM Storage On-line Support
The film scanners are used in clinical imaging applications - teleradiology,
image distribution, archiving and film copying. To transmit images, the technologist enters the patient’s
name and any additional demographic or historical data requested.
Patient demographic data entry is fully configurable to meet the
requirements of a DICOM archive or PACS system. Other information
such as imaging site, image source, and date and time are automatically
transmitted with each image. Once this information is entered, the
operator positions the film on the input tray and presses the enter
key to initiate the scan. The rest is automatic. The film is scanned
in one pass and then automatically mapped to an optimized 12 bit
grayscale image for transmission. No operator adjustments to the
image contrast and brightness are required. The processed image
is then moved to the FrameStore computer. The next film can be scanned
as soon as the previous film feeds out of the scanner. Once the first film has been scanned, automatic transmission to
either a remote site or a local network destination begins. No operator
action is required. The FrameStore system automatically connects
to the remote destination and begins image transmission while additional
images can be scanned. Communication options include modem connections
via standard phone lines or ISDN lines; LAN, WAN or Internet network
connections via IOC Sockets and DICOM out to an image archive or
PACS system. For Internet or other unsecured network connections,
IOC Sockets technology includes data encryption and user authorization
features. The Film DigitizerStation features Images-on-Call proprietary Controlled Quality Wavelet Compression™ to take full advantage of the available image transmission bandwidth. Advanced Wavelet compression algorithms can be used to dramatically reduce the amount of data that must be transmitted while minimizing the impact on image quality. Transmission quality levels are preprogrammed into the Handheld Controller and range from lossless data compression to Wavelet compression options for the highest speed transmission.

The
Images-on-Call Film DigitizerStations make scanning of standard
radiographs and transmission of the digital images to remote sites
quick and convenient. The Film DigitizerStations consist of twelve
bit film scanners and IOC FrameStore computers that control the
scanners and transmit the images.
