Left: Distribution of pixel intensity for channel data containing only noise. The theoretical threshold is an effective approximation of the 95% confidence interval, compared to the empirically measured value. Right: The confidence interval remained a robust approximation of noise pixel variance for simulations additionally containing blood. Data shown depicts a 100% fractional moving blood volume realization with −10dB SNR.
