FIELD: medicine.
SUBSTANCE: invention refers to medical equipment. The multipath ultrasonic signal receiver contains a probing beam shaper, a sensor receiving line conditioners, multipliers, delay lines, adders. After formation of four reception beams Ri,j j = 1, 2, 3, 4 on the i-th probing using ray generators 3, 4, 5, 6, reception beams Ri,1 and Ri,2 are multiplied by means of 7 and 8 multipliers, respectively, by W2 and W1 weighting factors and are fed to adder 13 and adder 14, respectively. The second inputs of adder 13 and adder 14 receive the data of reception beams Ri-1,3 and Ri-1,4 formed on the previous i-1-th probing and multiplied by W2 and W1 factors, respectively. As a result, two first line images L3i-4 and L3i-3 are formed at the outputs of adder 13 and adder 14. Then, the data of the third reception beam Ri,3 and the fourth reception beam Ri,4 are delivered from multiplier 9 and multiplier 10, respectively, to delay line 11 and delay line 12, carrying the signal delay by a probing tact and will be used for formation of image lines based on the results of i+1-th sensing, and delay lines 11, 12 represent a standard FIFO-type memory. The third line of the image is formed by addition by means of adder 15 of the second and the third reception beams Ri,2, Ri,3, delivered from receiving lines driver 4 output and receiving lines driver 5 output, respectively.
EFFECT: application of this invention provides a high frame rate when imaging the moving cardiac structures with geometric distortion compensation.
