 note = {The efficacy of the image transfer system (Photophone, Image data Inc.) was evaluated. Compared withe film image, the display image presented a 20% lower resolution on the density chart and a 30% lower dynamic range in contrast resolution. In spatial resolution, 0.6 line pair/mm was the limit in the low resolution mode and in maximum spatial resolution it was 4 line pair/mm in the high resolution mode at a magnification of 6.5 times. For image quality analysis with the spatial resolution chart, the existence of moire in high contrast cases was one of the limiting factors. At present, there is no complete remedy for the problem, a shift in focus being the only solution. However, this remedy is the trade-off for spatial resolution. Data size of images ranged between 10K bites to 45K bites according to the image mode and image series. Actual image transfer times depended on the image size. However, regular image transfer time was almost 40 sec. with the medium resolution mode. These results suggest that this image transfer system was suitable for high contrast and low resolution image transfer (i.e. CT and MR images) and had a limitation in low contrast and high resolution image transfer such as chest X-P., 論文},
