title: A Concord chair for improved contrast ventriculography.
abstract: This paper describes the adaptation of the G.E.C. Concord X-ray couch for controlled contrast ventriculography. The addition of a chair fixture and head-fixing device coupled with a suitable radiographic procedure has made contrast ventriculography a fairly simple and sure technique.
