WebThe signal to noise ratio (SNR) is simply the average image signal in a given region divided by the noise around that region. This can be a useful first measurement but the more important quantity typically is the contrast to noise ratio (CNR), which is simply the ratio of the contrast between the signal in a given region and the background. WebThe performance of the PRR was improved by background restriction with the PRR-TA method; the number of false-positive SDRs decreased, and the ability to detect true-positive SDRs increased, improving the signal-to-noise ratio. Further development and validation of the method is needed within other …
