The controls will not work on this image. Values can be changed by typing in the text fields or clicking on the scroll bars. There is a choice of units for Image Size, Pixel Depth, Transfer Rate, and Transfer Time. Other examples can be tested by entering different values in Table 3. Other plain radiographs and mammograms may also require these large matrix sizes.
Compression ratios vary widely.
High compression ratios can be obtained if the initial image is coded inefficiently, by using a matrix size that is much larger than the resolution of the image or including large blank or constant-intensity areas. Transfer rates also vary. Our current system provides excellent performance for nuclear medicine and would be reasonable for several other modalities, especially with compression. In conclusion, we have implemented cable modem access to our Web-based nuclear medicine department. Cable modem access is a considerable improvement compared with an Internet connection via an analog telephone modem.
