A Fax (top) and an email (lower) from David Rayner dated 03 August 1995 and 01 April 96, respectively, discussing the 7 T initiative. The approximate pricing supplied is blanked out. The color markings in the 1996 email identify our deliberations in CMRR at the time. Ultimately we decided on the 7.0/900-cm bore magnet; this design was employed on all 7 T systems installed until 2011 when two new, actively shielded 7 T magnets with 830 and 900 cm bore diameters were developed.
