Abstract
An ultrasound imaging system (100) may automatically analyze a pulse wave Doppler spectrogram to determine high quality and low quality cardiac cycles. Based on the determination, the ultrasound imaging system (100) may exclude the low quality cardiac cycle from being used in calculations of parameter measurements such as peak systolic velocity, end diastolic velocity, and resistance index. In some examples, the ultrasound imaging system (100) may provide a visual indication on the display (138) which cardiac cycles were excluded from the measurements.
Claims15
A system comprising:
- a computer readable memory storing spectral Doppler data;
- a display;
- and
- at least one processor configured to:
- determine whether individual ones of a plurality of cardiac cycles in the spectral Doppler data are of high quality or of low quality, based at least in part on heart rate variability;
- and
- generate display data based on the determination,
- wherein based on the display data, the display is configured to provide one or more of
- a visual indication of cardiac cycles of the plurality of cardiac cycles determined to be of high quality and
- a visual indication of cardiac cycles of the plurality of cardiac cycles determined to be of low quality.
The system 1, further comprising an ultrasound probe configured to acquire the spectral Doppler data.
A method comprising:
- determining whether individual ones of a plurality of cardiac cycles in spectral Doppler data are of high quality or of low quality, based at least in part on heart rate variability;
- and
- displaying the spectral Doppler data and a visual indication of one or more of cardiac cycles of the plurality of cardiac cycles determined to be of high quality and cardiac cycles of the plurality of cardiac cycles determined to be of low quality.
