A teleradiology link based on standard personal computers and a flat-bed CCD scanner was tested. A 64 kbit/s dial-up digital ISDN telephone line was used for transmission. A total of 254 films (174 uncompressed, 80 compressed) were sent. Ninety-six per cent of the uncompressed images and 98% of the compressed images were considered technically acceptable. The total diagnostic agreement between the acceptable transmitted images and the original films was 98%. Image quality was sufficient for diagnosis in CT and conventional chest and bone radiographs. However, a 256-step gray scale of the scanner was not sufficient for demanding situations, such as overexposed images with a high contrast gradient. The average speed of transmission was 60 kbit/s, which was considered adequate. The tested system suggests that a teleradiology link based on standard personal computers and programs works in situations where instant consultation is needed. However, the image digitization time with the prototype system was quite long, and a better user interface is under development.
Consolidating personal computers (PCs) with nuclear medicine technology can create high computational power comparable with that produced by vendor-specific computer equipment, and at more affordable prices. The integration of a standard platform and operating system with a large installed base has enabled our department to maintain itself at the cutting edge of technology with minimal expense. Along with the savings from the purchase of PC software and hardware come the added advantage of rapid training of staff with minimal in-house effort, especially given the vast educational support in the general community. The integration of a standard platform and operating system with a large installed base has provided the nuclear medicine department with computational resources once unheard of because of economies of scale. The acceptance and integration of a pervasive, flexible technology into nuclear medicine have shown that state-of-the-art studies can be performed at low cost.
