We have developed a ultrasound diagnostic system with a facsimile on which ultrasound images can be displayed, and we can get cheap hardcopies easily with that system. 
In the technique for a display of continuous tone pictures on a bilevel display equipment such as a facsimile, it has been found that the distinction of the dot-patterns has a great influence upon their gray-scales.
We have found that the dot-pattern influence upon their gray-scales is due to overlap of the dots. In such a case, the dot-pattern which, they say, is good for minimizing a mosaic is not necessarily good for gray-scales.
The transmission of the ultrasound images to a facsimile installed in another station is demonstrated. The transmission is realized easily, because the facsimile is standardized.
