X-ray scanner with means for conventional radiography

摘要

The scanner includes a patient table having a table support and a moveable table top for receiving a patient. The scanner further includes a computer tomography (CT) imaging device for obtaining an image of a patient placed on the table top. The CT imaging device has an X-ray source and an X-ray detector mounted for rotation about an axis substantially parallel to the longitudinal direction of the table top, the table top being movable along this axis. Also included are a second conventional radiographic imaging device having a cassette for receiving a sheet of an x-ray sensitive material. The table top has a chamber for receiving the cassette of a length that is substantially equal to the length of the table top. Preferably, this chamber contains a trolley for carrying the cassette and a driving device for moving the trolley in the longitudinal direction of the table top over substantially the full length of the chamber.
