摘要：
The invention relates to the field of medical instrumentation, in particular, to devices for ultrasound echolocation internal organs, and can be used in medical diagnostic systems. It reduces hardware costs for implementing adaptive focusing affecting the quality of the formed ultrasound image. Through the use of the same hardware apparatus may perform multipath reception mode cardiac studies to provide high frame rate imaging moving structures of the heart and to implement an adaptive algorithm for compensating the phase aberrations in the study of surface organs or during abdominal studies. The apparatus comprises a receiving-transmitting unit, which is composed of N channel reception signals. Each receiving channel signals 1 / j is connected through an individual ADC 2 with a primary RAM 3 FIFO type, which is connected to a filter 4. The filter interpolator interpolator L 4 is connected to the secondary modules RAM FIFO type 5 / L, the output of each of which is connected to the first input of the corresponding channel adder 6 / i. The output of each combiner channel 6 / i, is connected to the corresponding input signal amplitude shaper 7 / i, the first input of the corresponding individual switch 10 / i and a corresponding common switch input 9. The output of each driver signal 7 amplitude / i connected to the corresponding input of the comparator 8. output of comparator 8 is connected to the control input of the switch 9. The overall general switch output 9 is connected to the second inputs of all the individual switches 10 / i. The output of each individual switch l0 / i is connected to the second input of the adder 6 channels / i adjacent reception channel signals 1 / (j-1), 2 ZP f ly-1-yl.Полезная модель относится к области медицинского приборостроения, в частности, к устройствам для ультразвуковой эхолокации внутренних органов, и может быть использовано в системах медицинской диагностики. Обеспечивает снижение аппаратных затрат для реализации адаптивной фок
