Any physician or scientist who has spent at least one year in training in the Department of Radiology at the University of Chicago, or who has served on the clinical or basic science faculty of the Department, is a member of the Society. Members are encouraged to contribute annually to the Society. In addition, Sustaining members have made contributions of $1,000. Benefactors have made contributions of $5,000 and Lifetime members have made contributions of $10,000. At these levels of giving, the donors are placed in the Culver Society, the premier giving club on a permanent plaque displayed within the Department.
As all donations are channeled through the University of Chicago, donors are recognized by the University of Chicago Medical Center and Biological Sciences Division. All donors receive gift receipts from the University and are listed in the Honor Roll of Donors as published by the Division. Additionally, members receive the medical alumni publication of the Division, "Medicine on the Midway" and invitations to other alumni gatherings.
