Abstract

Изобретение 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 улучшения динамики формирования ультразвукового изображения. Устройство содержит приемно-передающий модуль, в состав которого входят приемные каналы сигналов с элементов ультразвукового датчика. Каждый приемный канал электрически соединен через индивидуальный аналого-цифровой преобразователь с первичной оперативной памятью типа FIFO, которая в свою очередь соединена с первичным фильтром-интерполятором. Первичная оперативная память типа FIFO соединена с первичным блоком сдвиговых регистров. Выходы первичного фильтра-интерполятора и первичного блока сдвиговых регистров соединены с соответствующими входами двух вторичных фильтров-интерполяторов. Первичный блок сдвиговых регистров, первичный фильтр-интерполятор и вторичные фильтры-интерполяторы соединены через вторичные блоки сдвиговых регистров с соответствующими входами формирователей лучей. Каждый формирователь лучей соединен с соответствующим сумматором каналов и включает последовательно соединенные мультиплексор, вторичную оперативную память типа FIFO и умножитель. Каждый фильтр-интерполятор представляет собой фильтр-интерполятор с фиксированной симметричной импульсной характеристикой. В первичном фильтре-интерполяторе сдвиговые регистры объединены в один ряд, соединенный с первичной оперативной памятью типа FIFO. Во вторичном фильтре-интерполяторе сдвиговые регистры объединены в два ряда, один изThe invention relates to the field of medical instrumentation, in particular to devices for ultrasonic echolocation of internal organs, and can be used in medical diagnostics systems, provides a reduction in hardware costs to improve the dynamics of ultrasound imaging. The device contains a receiving-transmitting module, which includes receiving channels of signals from the elements of the ultrasonic sensor. Each receiving channel is electrically connected through an individual analog-to-digital converter with a primary random access memory of the FIFO type, which in turn is connected to the primary interpolator filter. Primary FIFO memory is connected to the primary block of shift registers. The outputs of the primary interpolator filter and the primary block of shift registers are connected to the corresponding inputs of two secondary interpolator filters. The primary block of shift registers, the primary filter interpolator and the secondary interpolator filters are connected via secondary blocks of the shift registers to the corresponding inputs of the beamformers. Each beamformer is connected to a corresponding channel accumulator and includes a series-connected multiplexer, secondary operational memory of the FIFO type, and a multiplier. Each filter interpolator is a filter interpolator with a fixed symmetric impulse response. In the primary interpolator filter, the shift registers are combined into one row, connected to the primary memory type FIFO. In the secondary interpolator filter, the shift registers are combined in two rows, one of
