Abstract
An imaging system is provided for various non-invasive medical and non-medical imaging. The imaging system includes a tunable X-ray source for emitting X-rays having a substantially monoenergetic spectrum and an energy discriminating detector for generating a detector output signal in response to the X-rays incident on the energy discriminating detector. The imaging system also includes a system controller comprising an X-ray controller for operating the tunable X-ray source and data acquisition circuitry for acquiring the detector output signal from the energy discriminating detector.
Claims26
An imaging system comprising:
- a tunable X-ray source configured to emit X-rays having a substantially monoenergetic spectrum;
- an energy discriminating detector configured to generate a detector output signal in response to the X-rays incident on the energy discriminating detector;
- and
- a system controller comprising an X-ray controller configured to operate the tunable X-ray source and data acquisition circuitry configured to acquire the detector output signal from the energy discriminating detector.
An imaging system comprising:
- an X-ray source configured to emit X-rays having a substantially monoenergetic spectrum;
- an energy discriminating detector configured to generate a detector output signal in response to the X-rays incident on the energy discriminating detector;
- a system controller comprising an X-ray controller configured to operate'the X-ray source and data acquisition circuitry configured to acquire the detector output signal from the energy discriminating detector;
- and
- image reconstruction circuitry configured to generate at least one composition image based on the detector output signal.
A method of generating a composition image, the method comprising:
- selecting a desired monoenergetic X-ray spectrum for imaging an object of interest;
- emitting X-rays generally at the desired monoenergetic X-ray spectrum through the object of interest;
- detecting the X-rays attenuated by the object of interest via an energy discriminating detector;
- generating a detector output signal in response to the X-rays detected by the energy discriminating detector;
- and
- generating at least one composition image based on the detector output signal.
A computer readable media, comprising:
- code adapted to select a desired monoenergetic X-ray spectrum for imaging an object of interest;
- code adapted to trigger emission of X-rays generally at the desired monoenergetic X-ray spectrum through the object of interest;
- code adapted to detect the X-rays attenuated by the object of interest via an energy discriminating detector;
- code adapted to generate a detector output signal in response to the X-rays detected by the energy discriminating detector;
- and
- code adapted to generate at least one composition image based on the detector output signal.
