摘要： PURPOSE:To improve the effective accuracy of A/D conversion with a simple configuration by using the oversampling method for digital processing of ultrasonic signals and then performing accumulation addition processing after shifting to a low frequency. CONSTITUTION:A plurality of analog reception signals received by a transmitter/ receiver 23 consisting of a group of aligned wave reception element are digitized by a A/D converter and then are mixed with a reference signal, where time is precisely controlled, from a digital reference signal generation circuit 19 and then are converted to low-frequency signals. Then, accumulation addition processing is performed by a digital adder 4 for accumulation addition, thus extracting low-frequency components. Then, the signals which are subjected to accumulation addition are delayed by a digital delay circuit 7 and then signals which are delayed by a digital adder 3 are added, thus phasing the digital signal accurately.

摘要： PURPOSE: To obtain a needle ultrasonic probe which is ideal for the diagnosis of the nature of a tissue and higher resolution photographing thereof at a deep part within a specimen by a method wherein a part having an ultrasonic converter of an inner needle is exposed from the tip of an outer needle during the transmitting or receiving of an ultrasonic wave and the inner needle is moved with respect to the outer needle to scan the ultrasonic converter. CONSTITUTION: An hollow intermediate cylinder 2 for holding is formed inside an hollow outer needle 1 with a puncture needle-shaped tip and moreover, an inner needle 3 carrying an ultrasonic converter 10 is fitted inside. The inner needle is pierced by a signal line 30 to transmit a signal transmitted or received by the ultrasonic converter and a tube 4 to supply or discharge an ultrasonic transmission medium. A driver 31 and a drive controller 32 are attached on an end part opposite to the sharp tip of the outer needle 1 and the inner needle 3 is turned and driven in translation. When the tip of a probe reaches an interest part in the puncturing of the probe into a human body, the outer needle 1 is pulled slightly so that a non-stretching film is broken to expose the intermediate cylinder 2 and the inner needle 3. Thus, the transmission medium is supplied into an organic tissue through a tube 4 in the inner needle to transmit or receive an ultrasonic wave driving the inner needle 3.
