Abstract
An X-ray computed tomography (CT) scanner includes a plurality of X-Ray sources and detectors mounted about an opening where scanning takes place. The X-Ray sources and detectors are arranged to oscillate back and forth in opposing first and second rotational directions about the opening, or in the same rotational direction about the opening, in order to generate a cross-sectional image of an object located within the opening.

An X-ray computed tomography (CT) scanner comprising a scanning setup comprising a plurality of X-Ray sources and detectors mounted about an opening where scanning takes place, wherein the X-Ray sources and detectors are arranged to oscillate back and forth in opposing first and second rotational directions about the opening and an axis of rotation of the scanner that passes through the opening in order to generate scanned slice data of an object located within the opening.
An X-ray computed tomography (CT) scanner comprising a scanning setup comprising more than two X-Ray sources and more than two detectors mounted about an opening where scanning takes place, wherein a scanning setup is arranged to rotate about an axis of rotation of the scanner in order to generate scanned slice data of an object located within the opening.
An X-ray computed tomography (CT) scanner comprising a scanning setup comprising a plurality of X-Ray sources and detectors mounted about an opening where scanning takes place, wherein the X-Ray sources and detectors are arranged to perform alpha sized rotational motions in the same rotational direction about the scanner's axis of rotation in order to generate scanned slice data of an object located within the opening.
A method for medical imaging comprising the stems of:
- providing an X-ray computed tomography (CT) scanner comprising a plurality of X-Ray sources and detectors mounted about an opening where scanning is designed takes place,
- locating an object to be scanned within the opening, and
- performing alpha sized rotational motions in the same rotational direction about the scanner's axis of rotation in order to generate scanned slice data of an object located within the opening.
A method for medical imaging comprising the stems of:
- providing an X-ray computed tomography (CT) scanner comprising a plurality of X-Ray sources and detectors mounted about an opening where scanning is designed takes place,
- locating an object to be scanned within the opening, and
- oscillating the X-Ray sources and detectors back and forth in opposing first and second rotational directions about the opening and an axis of rotation of the scanner that passes through the opening in order to generate scanned slice data of an object located within the opening.
An X-ray computed tomography (CT) scanner comprising a plurality of X-ray tubes that are arranged to emit radiation towards a single detector in order to obtain scanned slice data of an object, wherein the CT scanner is defined having a maximal field of view (FOV) when all X-ray tubes are used for obtaining the scanned slice data, and wherein the CT scanner is configured to adapt the FOV to be smaller than the maximal FOV by activating only some of the X-ray tubes for obtaining the scanned slice data of an object.
An X-ray computed tomography (CT) scanner comprising a plurality of X-ray tubes that are arranged to emit radiation towards a single detector in order to obtain scanned slice data of an object, wherein the CT scanner is controlled to activate at least some of the X-Ray tubes at different powers while obtaining scanned slice data of an object.
