AUTOMATED SEQUENCE OF OPERATIONS IN TWO-PLANE PW MODE FOR ULTRASOUND EVALUATION OF STENOSIS Russian patent published in 2017 - IPC A61B8/08 

FIELD: medicine.

SUBSTANCE: ultrasonic system with a probe with a matrix array capable of operating in a two-plane mode is used to evaluate the blood vessel stenosis by simultaneously displaying two vessel images in a two-plane colour Doppler mode, one of which is a longitudinal section and the other is a cross section. Two planes of images intersect along the line of the Doppler sounding beam used for the PW (impulse) Doppler mode. A graphic image of the reference volume (SV) is set on the blood vessel at the peak velocity location in one image, then set on the blood vessel at the peak velocity location in the other image. When the location of the reference volume is moved in one image, the location of the plane and/or reference volume in the other image is adjusted accordingly. Then, from the location of the reference volume, spectral Doppler mode data is acquired and displayed.

EFFECT: ensured possibility of using a sequence of ultrasound operations for a vascular procedure that eliminates errors and inaccuracies in evaluation of blood vessel stenosis, simplifies the procedure for blood vessel stenosis evaluation.
