acceptable levels of cryoges
The 'safe' level of liquid helium depends on the specific magnet that you have. 40% is accurate for some magnets.

acceptable levels of cryoges
A quench is possible around a helium level of 40%. An acceptable cryogen level should be above 50% if you don't like risks.

Technical Specifications
Hi,
I'm kind of new to MRI technology and am doing a comparison of various MRI equipment. Could somebody give me a brief summary of the technical specifications I should pay special attention to?
E.g. High slew rate is preferable
High transmit power (at least 15kW)
High gradient field strength
Helium usage (in terms of maintenance costs)
Etc.

What other factors play a huge role in differing price?

Thanks in advance

How to setup a MRI room? + questions
I'm planning to purchase a used 1.0-1.5T MRI and I had a few questions.

From what I gather, I need a 480V line, correct? The unit 1.5T takes about 150amps. Does it suck all that power 24x7, or when it's on? If not all the time then how much when it's on standby?

What kind of cooling would I need? From what I read a helium? gas setup? What about A/C? how strong would I need?

What about the room. What size does it have to be? does it need any special insulation?

And are there any companies in Europe what can design and build a room for it?

Siemen MRI Concerto
I am looking to buy the open MRI Siemen Concerto to be shipped to Tanzania. The reason I am looking open MRI is due to poor technology in Tanzania, lack of Helium, low maintanance machine and ... Is there anyone who has different thought or Ideal? What are the posibility to find MOBILE concerto? Do you know anyone who has this in stock?

Any thought or ideals will help. Thank you
