Abstract: An improved matrix switch circuit comprising an array of analog switches disposed in the form of a matrix and one or more control memories for storing control signals which cause their respective switches of the array to open or close. An interface is provided between the control memories and the array of the switches. The interface receives the control signals from the control memories and holds them. The held signals are then supplied to the switches of the array. While the switches of the array are being controlled according to the control signals held in the interface, the contents of the control memories can be changed at any desired instant.

Abstract: An echo signal receiver receives higher level echo signals reflected from strong reflections sources or reflecting sources at areas close to a probe in a range of higher frequencies, and also receives lower level echo signals reflected from weak reflection sources or sources at areas remote from the probe in a range of low frequencies. The echo signal receiver comprises a multiple stage amplifier circuit for receiving the echo signal. Outputs from amplifiers at front stages are delivered via filters having higher frequency bands, and outputs from amplifiers at rear stages are delivered via filters having lower frequency bands. The outputs are passed through the filters and then combined into a single processed echo signal. As an alternative, a video signal derived from an echo signal which has passed through a circuit for varying frequency characteristics is compared with a reference voltage by a comparator, which produces an output that is rounded off by removing high frequency components in a low pass filter. The rounded off signal is fed to a circuit for varying frequency characteristics to control the same to change its frequency ban while the signal is being received. In another embodiment, the echo signal is received through a variable low cut filter having a cutoff frequency which can be increased or reduced dependent on the level of the echo signal.

Abstract: In an ultrasonic diagnostic apparatus of this invention, the dimension of a sample volume can be adjusted both in the depth and azimuth directions in forming a transmission beam for both a B mode and a Doppler mode with the use of a common beam forming data, and an amount of radiation of the ultrasonic wave to a body to be examined can be reduced. In the B mode operation, transmission and reception of a sharply focusing ultrasonic beam are carried out based upon a B mode beam forming data, while in the Doppler mode, transmission and reception of a predetermined blurringly focusing ultrasonic beam are carried out based upon a beam forming data which is obtained by modifying the B mode beam forming data.

Abstract: To apply our new invention in the most preferred application mode, we used an ultrasonic diagnostic system that can instantaneously switch over to the CW Doppler method or B-mode imaging method when both methods are combined using a commonly applicable array probe. The ultrasonic diagnostic system based on this new invention is configured with the following features:Dividing multiple vibrating elements of a commonly applicable array probe (3) into two groups, (3T) and (3R), andconnecting the first vibrating element group (3T) to the first transmitting driver (2T) to which low voltage is supplied by the power supply (4), and connecting the second vibrating element group (3R) to the second transmitting driver (2R) to which high voltage is supplied by the power supply (4). For applying the CW Doppler method:Driving the first vibrating element group by the first transmitting driver with a low-voltage continuous wave to transmit a continuous ultrasonic wave and receive an echo signal with the second vibrating element group; For applying the B-mode imaging method:Driving the second vibrating element group by the second transmitting driver using a high-voltage pulse wave to transmit an ultrasonic pulse wave and receive an echo signal with the second vibrating element group.
