Ultrasound System Revision! Why is the revision important ?
Older revision software can cause a system to be lacking in image quality, Doppler sensitivity, even color sensitivity and uniformity, as well as the latest calculation packages like tissue Doppler etc. Many bargain system on the market are due to the fact they have very old software.
Late model revision systems cost a little more but are by far worth the extra investment. In many cases the newer revision system will accept newer higher resolution transducers that the older systems are not capable of operating. And of course as a extra benefit, newer revision systems usually include faster CPUs, more memory and faster network adapters, allowing the systems to operate much more efficiently.
So keep this in mind the next time you are looking to purchase a system. If you have a very small budget, a older system can still get the job done in most cases for general imaging, and allow you to build your capitol to purchase that dream machine down the road
