CNI hourly scan rate adjustments

by on July 2, 2019 4:05 pm
Charges at a service center like the CNI are closely monitored by Stanford’s financial officers.  The principles are to set the rates so that the service center does not make or lose much money in any given year.  The costs of running the CNI are the staff salaries, scanner maintenance, and supplies.  In case you… Read more CNI hourly scan rate adjustments

Data management and storage at the CNI

by on May 31, 2016 5:18 pm
In planning the CNI environment, we made a risky decision: We committed to providing the community with data management services. Many of you know that most MRI centers do no more than hand the user a DVD at the end of the session, and wish them well. Or perhaps they allow the user to copy the data… Read more Data management and storage at the CNI
