Abstract
A method for scanning a stream of objects includes continuously acquiring raw data of the stream of objects using an X-ray system, that includes a detector. The raw data of the stream of objects is rebinned into at least one two-dimensional sinogram. A leading edge and a trailing edge of a first object of the stream of objects is determined from the at least one two-dimensional sinogram and a three-dimensional image of the first object is reconstructed using the at least one two-dimensional sinogram.

A method for scanning a stream of objects, said method comprising:
- continuously acquiring raw data of the stream of objects using an X-ray system, the X-ray system including a detector;
- rebinning the raw data of the stream of objects into at least one two- dimensional sinogram using a first resolution;
- determining a leading edge and a trailing edge of a first object of the stream of objects from the at least one two-dimensional sinogram, wherein the raw data is rebinned using a second resolution different from the first resolution after the leading edge is detected;
- and
- reconstructing a three-dimensional image of the first object using the at least one two-dimensional sinogram.
A scanning system, comprising:
- a conveyor configured to transport a stream of objects through said scanning system;
- and
- a computed tomography (CT) system configured to generate an image of a first object of the stream of objects, said CT system comprising a detector and a control system, said control system configured to:
- continuously acquire raw data of the stream of objects from said detector;
- rebin the raw data of the stream of objects into at least one two- dimensional sinogram using a first resolution;
- determine a leading edge and a trailing edge of the first object from the at least one two-dimensional sinogram, wherein the raw data is rebinned using a second resolution different from the first resolution after the leading edge is detected;
- and
- reconstruct a three-dimensional image of the first object using the at least one two-dimensional sinogram.
A computed tomography (CT) system, comprising:
- a radiation source;
- a detector configured to detect radiation emitted from said radiation source;
- and
- a control system comprising:
- an acquisition subsystem configured to continuously acquire raw data of a stream of objects from said detector;
- an object detection subsystem configured to:
- rebin the raw data of the stream of objects into at least one two- dimensional sinogram using a first resolution;
- and
- determine a leading edge and a trailing edge of a first object of the stream of objects from the at least one two-dimensional sinogram, wherein the raw data is rebinned using a second resolution different from the first resolution after the leading edge is detected;
- and
- a reconstruction subsystem configured to reconstruct an image of the first object using the at least one two-dimensional sinogram.
