Abstract
A system for generating image data includes a voltage supply configured for applying a first voltage to generate radiation at a first energy level, and for applying a second voltage to generate radiation at a second energy level, an imager for generating a first set of image data based at least in part on the radiation at the first energy level, and for generating a second set of image data based at least in part on the radiation at the second energy level, and a processor for creating composite image data using the first and the second sets of image data.
Claims20
A method for generating image data, comprising:
- applying a first voltage to generate radiation at a first energy level;
- generating a first set of image data based at least in part on the radiation at the first energy level;
- applying a second voltage to generate radiation at a second energy level;
- generating a second set of image data based at least in part on the radiation at the second energy level;
- and
- creating composite image data using the first and the second sets of image data, wherein the first and second sets of image data are for a bodily region that has contrast agent;
- wherein the first and the second voltages are applied by operating a single voltage supply in a first mode and a second mode, respectively;
- wherein the acts of generating the first and second sets of image data are accomplished using a first portion of a detector and a second portion of the detector, respectively, wherein the first portion is different from the second portion, the first portion of the detector corresponding with the first mode of the voltage supply, and the second portion of the detector corresponding with the second mode of the voltage supply;
- and
- wherein the first portion of the detector and the second portion of the detector are located at a same layer of the detector.
