Design Analysis of a Wide-Band Picture Communication System

A design study of a Picture Communication Network is presented with special emphasis on those issues that differ from conventional networks. The large amount of data in an image together with the requirement for a rapid response time make a wide-band transmission medium a necessity. The wide-band medium is perceived as a collection of parallel broadcast channels. Four different logical organizations are proposed for this architecture. Design equations are developed and cost-performance curves are generated. Advantages of one organization over another under different circumstances are pointed out

Digital mammography, cancer screening: Factors important for image compression

The use of digital mammography for breast cancer screening poses several novel problems such as development of digital sensors, computer assisted diagnosis (CAD) methods for image noise suppression, enhancement, and pattern recognition, compression algorithms for image storage, transmission, and remote diagnosis. X-ray digital mammography using novel direct digital detection schemes or film digitizers results in large data sets and, therefore, image compression methods will play a significant role in the image processing and analysis by CAD techniques. In view of the extensive compression required, the relative merit of 'virtually lossless' versus lossy methods should be determined. A brief overview is presented here of the developments of digital sensors, CAD, and compression methods currently proposed and tested for mammography. The objective of the NCI/NASA Working Group on Digital Mammography is to stimulate the interest of the image processing and compression scientific community for this medical application and identify possible dual use technologies within the NASA centers

Rapid Display of Radiographic Images

The requirements for the rapid display of radiographic images exceed the capabilities of widely available display, computer and communication technologies. Computed radiography captures data with a resolution of about four megapixels. Large format displays are available that can present over four megapixels. One megapixel displays are practical for use in combination with large format displays and in areas where the viewing task does not require primary diagnosis. This paper describes an electronic radiology system that approximates the highest quality systems, but through the use of several interesting techniques allows the possibility of its widespread installation throughout hospitals. The techniques uses can be grouped under three major systems concepts: a local, high-speed Image Server, one of more physician\u27s workstations each with one or more high-performance Auxiliary Displays specialized to the radiology viewing task, and dedicated, high-speed communication links between the server and the displays. This approach is enhanced by the use of a progressive transmission scheme to decrease the latency for viewing four megapixel images. The system includes an Image Server with storage for over 600 4 megapixel images and high-speed link. A subsampled megapixel image is fetched from disk and transmitted to the display in about one second followed by the full resolution 4 megapixel in about 2.5 seconds. Other system components include a megapixel display with a 6 megapixel display memory space and frame-rate update of image roam, zoom and contrast. Plans for clinical use are presented
