Method and device for the ink flow - imaging using golay - coded excitation during transmission and pulse compression when receiving

摘要

Device for imaging of the flux of ultrasound - litter parts, comprising:an ultrasound - transducer array (2), which has a plurality of transducer elements,a transmitting device, which is connected with the transducer array (20) to the pulses of a set of selected transducer elements which form a transmit aperture, with a first coded pulse sequence during the first and the third transmitting of the activated four and with a second coded pulse sequence during a second transmitter activation, wherein the first to third transmitting activated by means of four at the same transmitter are focused focal position, the first coded pulse sequence is a function of a first folded broadcast code with a base pulse sequence is, the second coded pulse sequence is a function of a second folded broadcast code to the base pulse sequence, and the first and second broadcast code are complementary,a receiving device, which is connected with the transducer array (26) for receiving of the first to third bundle summed signals according to the first to third transmitting activated by means of four,a device (32) to the matched filters of the first and third bundle summed signals using a first set of filter coefficients which, on the..
