CT image quality assessment by a Channelized Hotelling Observer (CHO): Application to protocol optimization

Highlights • Necessity of an automatic and objective method for CT images quality evaluation. • CHO can be tuned to match the human observer by the addition of internal noise. • CHO helps in the optimization of CT protocols on scanners by the same manufacturer. • CHO cannot be generally employed on...
