Automated determination of bubble grades from Doppler ultrasound recordings.
INTRODUCTION: One of the difficulties in the development of automated algorithms for the detection of bubbles in Doppler ultrasound recordings is that expert labels are only available on an aggregate basis, i.e., the expert provides a single label for a recording which may contain many bubbles. It is thus very difficult to determine whether an algorithm is correctly identifying the actual bubbles or simply identifying the correct number of events, but mislabeling some events that are not due...Expand abstract
