AUTOMATED DOPPLER PULSE CYCLE SELECTION Russian patent published in 2018 - IPC A61B8/06 G01N29/00 G01S15/00 

FIELD: medicine.

SUBSTANCE: device (308) is configured for examining pulsatile flow, for deriving, based on the examined flow, spectral characteristics and for, based on the derived characteristics, determining which one or more pulse cycles are to be selected as representative of the flow. Cycles selected can be consecutive and amount to a predetermined number of cycles, for example, five. Cycles (200) subject to selection may initially be filtered out based on waveform anomalies, with the surviving cycles in a consecutive group of sufficient number being judged based on parameters such as waveform caliper measurements and other types of the characteristics. Good cycles are selected (202) based their lack of variation, with respect to the measured parameters, from each respective, parameter median over the spectrogram cycles not initially filtered. Present technique may, according to user selection, take into account additional parameters suited to particular medical application. Uses of the device include correctly identifying an artery by name.

EFFECT: automated Doppler pulse cycle selection is disclosed.
