Systems and methods for minimizing noncoplanarity artifacts |
摘要 |
The system and method of the present invention minimizes artifacts caused by noncoplanarity between source and detector component in a computerized tomography system. The source component produces a beam of penetrating radiation which is rotatable about an axis and is incident on the detector component; and non-coplanarity is defined by the collection of the positions of the source component which defines a first plane, and by the collection of positions of the detector component which defines a second plane axially spaced from the first plane. Data obtained during a scan of a body located between the source and detector components are processed to form two images, one image being based on data related to one side of a focal plane interposed between the first and second planes, and another image being based on data related to the other side of the focal plane.
