Abstract
An imaging system includes an x-ray source configured to emit a beam of x-rays toward an object to be imaged, a detector configured to receive x-rays that are attenuated by the object, a data acquisition system (DAS) operably coupled to the detector, and a computer operably coupled to the DAS and programmed to obtain scan data with two or more incident energy spectra, decompose the obtained scan data into at least three basis materials, generate an image of one of the at least three basis materials using the decomposed scan data, and replace at least one pixel in the image using decomposed data of another of the at least three basis materials.
Claims20
An imaging system comprising:
- an x-ray source configured to emit a beam of x-rays toward an object to be imaged;
- a detector configured to receive x-rays that are attenuated by the object;
- a data acquisition system (DAS) operably coupled to the detector;
- and
- a computer operably coupled to the DAS and programmed to:
- obtain scan data with two or more incident energy spectra;
- decompose the obtained scan data into at least three basis materials;
- generate an image of one of the at least three basis materials using the decomposed scan data;
- and
- replace at least one pixel in the image using decomposed data of another of the at least three basis materials.
A method of multi-energy imaging, the method comprising:
- selecting an imaging application for a multi-energy image acquisition;
- acquiring imaging data, based on the selected imaging application, with an x-ray source powered to a first keV and to a second keV;
- decomposing the acquired data into a three material combination;
- generating an image of a first material of the three material combination;
- and
- altering pixel data in the image using a imaging information of a second material of the three material combination.
A computer readable storage medium having stored thereon a computer program configured to:
- acquire energy-sensitive imaging data of an object;
- identify a material triplet of a multi-material combination;
- reconstruct an image based on the identified material triplets;
- and
- replace one material of the identified material triplet with another material of the identified material triplet in the image.
