Abstract
A CdZnTe solid state detector application specific integrated circuit is used for detection of radiation. The chip and circuitry is under control of a main computer which provides control signals to a solid state detector chip module which provides threshold level and count information to the computer for processing into an image. The processed image may be a tomographic image and/or a multispectral image wherein image colors represent different energy bands of received x-rays. The information used from different energy band images is used to identify different materials contained in an object being scanned.
Claims51
A radiation imaging apparatus comprising in combination:
- a source of radiation;
- a plurality of radiation detectors wherein each detector has an output which comprises at least three threshold data wherein each threshold data is a representative of a different radiation energy level received;
- a display means responsive to said plurality of radiation detectors for different threshold data for producing one or more images;
- wherein said display means includes a computer for controlling data acquisition, data analysis, and image production and display and
- further comprising means for adjusting threshold data levels to compensate for differences in output of different X-ray detectors.
