Abstract
A computed tomographic (CT) imaging system for performing a CT scan includes a detector array including a plurality of detector cells and a processor operationally coupled to the detector array. The processor is configured to receive first data regarding a first x-ray spectral range from a first detector cell, receive second data regarding a second x-ray spectral range different from the first x-ray spectral range from a second detector cell different from the first detector cell, and determine spectral information from the first data and the second data.
Claims23
A uted tomographic (CT) imaging system for performing a CT scan, said CT system comprising:
- a detector array comprising a plurality of detector cells;
- a processor operationally coupled to said detector array, said processor configured to:
- receive first data regarding a first x-ray spectral range from a first detector cell;
- receive second data regarding a second x-ray spectral range different from the first x-ray spectral range from a second detector cell different from the first detector cell;
- and
- determine spectral information from the first data and the second data.
Athod for scanning an object, said scanning comprises scanning an object by at least one of:
- scanning the object while varying a peak kiloelectronvolt to an x-ray tube;
- scanning the object with a filter such that a plurality of x-ray spectra are received by a detector array;
- and
- scanning the object such that elements of a detector array discriminate between a plurality of x-ray spectra and generate signals based on the x-ray spectra.
Athod for determining the presence of an analyte in an object with a computed tomographic (CT) imaging system, said method comprising:
- receiving first data regarding a first x-ray spectral range from a first detector cell;
- receiving second data regarding a second x-ray spectral range different from the first x-ray spectral range from a second detector cell different from the first detector cell;
- and
- determining spectral information from the first data and the second data.
