摘要： Ultrasonic echo signals are successively sampled and converted to digital echo data which are written into a first digital memory column by column and then read out row by row into a first buffer memory. The digital echo data which are derived in response to beams successively transmitted in a predetermined direction are written into columns of a second digital memory and read out of the memory in rows into a second buffer memory. The data stored in the first and second buffer memories are read out for digital-to-analog conversion and selectively applied within a television "frame" interval to control electron beam intensity of a single cathode ray tube so as to present tomographic and cardiographic images in different display areas of the tube.

摘要： A sector scan ultrasonic imaging system comprises a source of a plurality of square wave pulse trains each being delayed by a unit quantization time with respect to adjacent trains, and a plurality of transmitter circuits corresponding to the elements of a transducer array. The duration of each square wave pulse is an integral multiple of the unit quantization time interval. Each transmitter circuit includes a read only memory in which a set of different digital delay time data is stored for the corresponding transducer element and is arranged to be retrieved in response to each angle increment of the ultrasonic beam transmitted from the array. Further included are a data selector for selecting a pulse train in response to a pulse train selection data retrieved from the memory and a programmable counter for counting the pulses of the selected train to generate an output in accordance with a pulse selection data retrieved from the memory. An Exclusive-OR gate is further included to provide bit inversion of the selected pulse train in selective response to the binary state of a data retrieved from the memory so that the number of available square wave pulse trains is doubled. A gating circuit responds to the output of the counter by gating a pulse of the selected pulse train to the corresponding transducer element.

摘要： An ultrasonic probe particularly suitable for ultrasonic diagnostic equipments of the electronic scanning type is made up of a multiplicity of piezoelectric transducer elements, each in the shape of a rectangular plate with electrode films coated on both sides, arranged in a row at intervals and an acoustic impedance matching layer placed on the row of the transducer elements. The width-to-thickness ratio of each piezoelectric plate takes a value not greater than 0.8 and preferably between 0.4 and 0.7 so that the plate can vibrate in width expansion mode. It is highly preferable that the impedance matching layer has a laminated structure given by two layers which are different in acoustic impedance of the respective materials and individually have definite thicknesses.

摘要： An ultrasonic Doppler blood flowmeter has a Doppler scanning mode of operation to obtain information about blood speed and a B mode of operation to obtain information for a tomogram. In order to produce supplementary Doppler shift data for use during a B-mode scanning period, Doppler shift data from a phase detector is treated as complex data, and the difference in argument between two consecutive, complex Doppler shift data is detected. The supplementary Doppler shift data can then be calculated by an arithmetic circuit on the basis of the difference in argument between the consecutive complex Doppler shift data.

摘要： An ultrasonic probe has an elongated form with an end. A transducer element array is disposed in the probe for emitting ultrasonic wave frontward with respect to the end of the probe and receiving echo ultrasonic waves. The transducer element array converts the received echo ultrasonic waves into corresponding electric echo signals. The electric echo signals are processed according to a predetermined aperture synthesis technique, and thereby an image signal is generated on the basis of the electric echo signals. An image of a region in front of the end of the probe is reproduced in response to the image signal.

摘要： The present invention relates to an ultrasonic examination apparatus which transmits ultrasonic waves into a body to be examined and receives the echo signals therefrom for examination of the inside of the body. The ultrasonic examination apparatus measures acoustic characteristics such as nonlinear parameter within the body using the fact that the characteristic of the reception ultrasonic wave from the inside of the body is varied in accordance with variation of the characteristics within the body. The ultrasonic examination apparatus has first and second ultrasonic transducers for transmitting first ultrasonic pulse and second ultrasonic pulse, respectively. The frequency of the second ultrasonic pulse from the second ultrasonic transducer is higher than that of the first ultrasonic transducer. The first and second ultrasonic pulses are superimposed and transmitted into the body. The phase relation of the first and second ultrasonic pulses is controlled so that the modulation characteristic of the reception signal based on the non-linear effect assumes the maximum.

摘要： In an ultrasonic imaging system echo signals representative of the amplitude of ultrasonic energy returning along a plurality of angularly spaced paths are sampled at a constant speed and stored into a buffer memory. At a speed inversely proportional to the cosine of the angle of said path with respect to a reference line the echo samples are read out of the buffer memory and written into a specified area of a graphic memory at a constant speed in the direction of the rows thereof and at a speed proportional to the tangent of the angle of the path with respect to the reference line in the direction of the columns thereof. At a constant speed echo samples are read out of the graphic memory in the directions of the rows and columns and applied to a monitor to be displayed in a raster scan field.
