Abstract
A system includes acquisition of a spectral topogram of a target, determination, based on the spectral topogram, of an attenuation associated with each of a plurality of regions of the target and a composition of each of the plurality of regions, determination of imaging parameters associated with the plurality of regions based on the determined attenuation and composition, and acquisition of an image of the target based on the imaging parameters.
Claims20
A system comprising:
- an imaging system comprising an X-ray source and an X-ray detector, the imaging system to acquire a spectral topogram of a target;
- and
- a processor to execute program code to:
- determine, based on the spectral topogram, an attenuation associated with each of a plurality of regions of the target and a composition of each of the plurality of regions;
- determine imaging parameters associated with the plurality of regions based on the determined attenuation and composition;
- and
- transmit the determined imaging parameters to the imaging system,
- wherein the imaging system is to acquire an image of the target based on the transmitted imaging parameters.
