Abstract
The present invention pertains to an apparatus and method for medical imaging comprising rotating two X-ray source-detector pairs around an axis of rotation simultaneously to quickly acquire image data and form a computed tomography (CT) dataset. The sources can be configured to emit radiation from a plurality of discrete locations. The CT dataset can be utilized as a prior to reconstruct a three-dimensional image from subsequent bi-planar imaging with these source-detector pairs.
Claims19
A method of medical imaging comprising:
- rotating a first X-ray source-detector pair through a first set of angles around an axis of rotation;
- simultaneously rotating a second X-ray source-detector pair through a second set of angles around said axis of rotation, wherein said first set of angles and said second set of angles do not overlap;
- acquiring image data from said first X-ray source-detector pair and said second X-ray source-detector pair during rotation;
- and
- storing said image data to form a computed tomography dataset.
A method of medical imaging comprising:
- rotating two X-ray source-detector pairs around an imaging volume, wherein sources of said X-ray source-detector pairs are configured to emit radiation from pluralities of discrete locations on their faces;
- acquiring a computed tomography dataset during rotation of said two X-ray source-detector pairs;
- fixing said two X-ray source-detector pairs at a predetermined angle relative to one another;
- acquiring image data from said two X-ray source-detector pairs while stationary at said predetermined angle relative to one another;
- reconstructing a three-dimensional image from said image data;
- and
- utilizing said computed tomography dataset as a prior for reconstruction of said three-dimensional image.
An apparatus for X-ray computed tomography of a human patient comprising:
- a first X-ray source configured to emit radiation from a plurality of discrete locations on its face mounted on first end of a first connective axis;
- a first detector mounted on a first opposite end of said first connective axis;
- a second X-ray source configured to emit radiation from a second plurality of discrete locations mounted on a second end of a second connective axis;
- a second detector mounted on a second opposite end of said second connective axis and sharing an isocenter with said first X-ray source and said first detector;
- and
- image acquisition hardware configured to acquire data from said first detector and said second detector.
