Hello Manoj, Although I have not been involved with comparative studies on the machines you have mentioned, there is no doubt that you will not be disappointed if you go for these 'Top of the range' ultrasound machines. The ATL particularly is probably the best at present for Radiology. The GE logiq 700 is good too. There is strong competition now to have all the applications available for all the disciplines though you will find that the particular machines are built to be dedicated to only one main area even though they carry the applications for other areas. That is to say that the Research and Design finances are mainly dedicated to one area only. Once you have your machine and you wish to use it in a different area, if you pay a little extra you can have these other software applications in some machines "switched on" for you as they may already reside inside the machine just waiting. Acuson concentrate on Cardiac applications as does Hewlett packard. However the Sequoia (as well as the older work-horse models of the XP 5 & 10's) from Acuson is also good for Radiology too. If you are looking for a good GENERAL lower-range machine that has everything, try the GE Logiq 500. All the above are well established and extremely reliable equipments in their field. Recently there has been a big take-over of medical manufacturing companies by the big three, GE, Siemans and Philips. They have bought out the likes of HP medical, Acuson etc. From a functional view-point, the one thing to remember is that these machines have a lot on-board and therefore your sonographers will have to be prepared to relearn much when they take on a new machine and this should not be discouraged. If they are well trained they will not need much time to settle in with them as they are now designed with the 'ergonomics' in mind. Additionally the companies supply Applications Specialists who will come and show them how to quickly get around the essentials etc.
Hope this helps. Nick
