Filed:

Nov 26, 1997

Appl. No.:

8/978901

Inventors:

Kenneth L. Freeman - Stow OH
John J. Barni - Mayfield Village OH
David W. Hoffmeyer - Concord OH
Donald E. Negrelli - Gates Mills OH

Assignee:

Picker International, Inc. - Highland Heights OH

International Classification:

H05G 160

US Classification:

378 4

Abstract:

A gantry (A) has a bore defining a first patient examination region (12). A first x-ray source (B) is mounted to a frame (C) for rotation around the examination region (12). An arc of first radiation detectors (14) detects x-rays which have traversed the examination region. A first image reconstruction processor (18) reconstructs a tomographic image representation from signals generated by the first radiation detectors. An angiographic device (D) is positioned remote from the gantry along a longitudinal axis (25) for generating and displaying angiographic image representations on a display monitor (46). A second examination region is defined along the longitudinal axis (25) between a second x-ray source (36) and an image intensifier tube (38). A second processor (44) reconstructs the angiographic projection image representations from signals generated by the image intensifier tube (38). A C-arm (30) can be suspended from an overhead track (50) for supporting the second x-ray source (36) and the image intensifier tube (38).

International Classification:

A61B 6/00

US Classification:

378207

Abstract:

A computed tomography perfusion phantom includes a scanned plane configured to align with an imaging plane of a CT device. A sample rod extends through the scan plane and includes a plurality of adjacent cells. The plurality of adjacent cells are each constructed of materials having predetermined CT numbers and the plurality of adjacent cells include cell of a plurality of CT numbers. A drive motor is coupled to the sample rod and the drive motor moves the sample rod through the scan plane. A method of calibrating a CT device with the perfusion phantom includes aligning the scan plane of the perfusion phantom with an imaging plane of the CT device. The drive motor moves the sample rod through the scan plane of the perfusion phantom. A plurality of CT number measurements of the sample rod are acquired through the scanned plane of the perfusion phantom.
