Abstract
Official abstract text for this publication.
Among other things, computed tomography (CT) systems and/or techniques for generating projections images of an object(s) under examination via a CT system are provided. A surface about which the projection image is focused is defined and data yielded from vertical rays of radiation intersecting the surface and data yielded from non-vertical rays intersecting the surface are used to generate the projection image. In some embodiments, the projection image is assembled from one or more projection lines, which are respectively associated with a line-path contacting the surface and extend in a direction parallel to an axis of rotation for a radiation source. A projection line is indicative of a degree of attenuation experienced by rays intersecting a line-path associated with the projection line and emitted while the radiation source was at a particular segment of a radiation source trajectory.
First claim
Opening claim text (preview).
1 . A method for generating a projection image from volumetric computed tomography (CT) data, comprising: helically examining an object via radiation, such that a radiation source and a detector array rotate within a plane about an axis of rotation while varying, along the axis of rotation, a relative position between the plane and the object; defining a surface about which the projection image is focused; for a first view-angle, identifying first data generated by a first detector cell of…
