Reconfigurable computer tomography scanner
A CT scanner is reconfigurable to multiple orientations and positions. The scanner includes a gantry on which the x-ray source and x-ray detector are mounted. The gantry is mounted on a support and is rotatable about a scan axis relative to the support. The support is movable and/or pivotable relative to a frame, such that the scan axis can be vertical or horizontal.
1. A reconfigurable CT scanner comprising:
a frame;
a support mounted to the frame, the support pivotable about a pivot axis relative to the frame;
a gantry mounted to the support, the gantry rotatable about a scan axis relative to the support and rotatably connected to the support at the scan axis, the scan axis orthogonal to the pivot axis, the pivot axis spaced away from the scan axis, such that rotation of the gantry about the pivot axis rotates the scan axis between a position generally parallel to a floor to a position generally transverse to the floor;
an x-ray source mounted to the gantry;
an x-ray detector mounted to the gantry opposite the x-ray source, the scan axis between the x-ray source and the x-ray detector; and
a computer programmed to create a CT image based upon a plurality of images received from the x-ray detector at a plurality of rotational positions.
2. The reconfigurable CT scanner of claim 1 wherein the support is pivotable approximately ninety degrees about the pivot axis.
3. The reconfigurable CT scanner of claim 2 wherein the pivot axis is transverse to the scan axis.
4. The reconfigurable CT scanner of claim 1 wherein the support is slidable relative to the frame.
5. The reconfigurable CT scanner of claim 4 wherein the support is slidable vertically relative to the frame.
6. The reconfigurable CT scanner of claim 1 wherein the support is pivotable approximately ninety degrees about the pivot axis between a first position and a second position, and the gantry is rotatable about the scan axis when the support is in the first position and when the support is in the second position.
7. The reconfigurable CT scanner of claim 1 wherein the x-ray source is a cone-beam x-ray source.
8. The reconfigurable CT scanner of claim 1 wherein the support is pivotably connected to the frame at one end of the support.
9. The reconfigurable CT scanner of claim 1 wherein the support is pivotable between a first position generally parallel to a floor and a second position generally perpendicular to a floor.
10. A reconfigurable CT scanner comprising:
a frame;
a gantry including a cross section, and a first arm and a second arm extending from the cross section, the gantry mounted to the frame, the gantry slidable vertically relative to the frame and pivotable about a pivot axis relative to the frame, the gantry rotatable about a scan axis extending through the cross section, the scan axis spaced away from the pivot axis, such that rotation of the gantry about the pivot axis rotates the scan axis between a position generally parallel to a floor to a position generally transverse to the floor;
an x-ray source mounted to the first arm;
an x-ray detector mounted to the second arm opposite the x-ray source, the scan axis between the x-ray source and the x-ray detector; and
a computer programmed to create a CT image based upon a plurality of images received from the x-ray detector at a plurality of rotational positions about the scan axis.
11. The reconfigurable CT scanner of claim 10 wherein the pivot axis is orthogonal to the scan axis.
12. The reconfigurable CT scanner of claim 10 wherein the pivot axis is not parallel to the scan axis.
13. The reconfigurable CT scanner of claim 10 further including a support mounted to the frame, the support pivotable about a pivot axis relative to the frame, the gantry rotatably mounted to the support to rotate about the scan axis.
