Lowest Detectable Signal in medical PW Doppler Quality Control by means of a commercial Flow Phantom: a case study

• Abstract:

  PW Doppler Ultrasound (US) is commonly used in clinical practice for cardiovascular applications. Nowadays, the performances of a Doppler system are difficult to assess because a shared worldwide standard is lacking. This work aims at giving a contribution in the field, by defining a new index for PW Doppler Quality Control (QC) by using a commercial flow phantom, namely, the Lowest Detectable Signal in the spectrogram image, which scientific literature referred to as an index of PW Doppler sensitivity. A novel automatic algorithm for the estimation of such an index has been developed and validated through the results comparison with an observer judgement. Finally, a Monte Carlo Simulation has been carried out for the uncertainty analysis and robustness testing.
