摘要： An ultrasonic probe comprising a housing (4), a driven shaft (2) rotatably supported by the housing (4), a transducer (1) supported by the driven shaft (2) to be swingable on one side of the driven shaft (2), a drive shaft (7) rotatably supported by the housing (4) spaced apart from and in parallel relationship with the driven shaft (2) in the predetermined direction; a drive motor (6) supported on the housing (11) and drivably connected to the drive shaft (7); and a drive belt (10) intervening between the driven shaft (2) and the drive shaft (7). The transducer (1) emits and receives ultrasound through the housing (12) in a predetermined direction. It is possible to reduce the rotation radius of the transducer independently of the size of the electric motor by spacing the rotation axes of the drive motor and the transducer in order to provide an ultrasonic probe smaller in size.

摘要： An ultrasonic probe is provided which may be employed in medical applications to radiate an ultrasonic wave for inspecting the interior of a patient's body noninvasively. The ultrasonic probe includes a scan mechanism which consists of a rotating mechanism and a swinging mechanism. The rotating mechanism is designed to rotate a cylindrical holder having installed thereon a piezoelectric element which emits an ultrasonic wave and receives the echo. The swinging mechanism is designed to swing a rotary base which supports the rotating mechanism to swing the cylindrical holder about an axis of rotation extending perpendicular to that of the piezoelectric element.

摘要： An ultrasonic probe comprises an element section (1) for transmitting/receiving an ultrasonic wave, a relay cable (2) connected to th e element section (1), and an oscillating mechanism section for oscillating th e element section (1). The cross section of the relay cable (2), perpendicular to the rotation axis (3) of the oscillation of the element section (1) by th e oscillating mechanism section, has a shape comprising two or more arc portio ns smoothly connected to each other, specifically has an S-letter shape or an inverted S-letter shape. The relay cable (2) is led out from the side of the oscillation axis (3) of the element section (1). Thus, the stress on the rel ay cable (2) can be dispersed during the oscillation of the element section (1) , thereby improving the durability of the relay cable (2).

摘要： An ultrasonic imaging system comprises a transducer array including a plurality of elongated piezoelectric transducers successively arranged along a curved surface for emission of diverging beams of acoustic energy and an acoustic diverging lens affixed to the curved surface for increasing the angle of divergence of the emitted acoustic energy. The system includes a source for successively generating burst energy and means for selectively establishing a connection from the energy source to a subarray of the transducers to transmit a beam of acoustic energy therefrom and shifting the connection to the next subarray by at least one transducer in response to the generation of subsequent acoustic energy to cause the emitted acoustic energy to be angulated in an arc scan format. Means are provided for compensating for differences in energy level resulting from the differences in the path-length of the acoustic lens.

摘要： An ultrasonic imaging system includes a linear array of transducers of which a group of successively arranged transducers is selected and successively shifted to the next by at least one transducer. The transducers of the selected group are successively activated at respective delay times to transmit a radial scan beam which appears to emanate from a hypothetical point source located behind the transducer array. A scan converter is provided for conversion of analog echo signals in sector scan format to digital echo data in raster format for visual display.

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 comprises an ultrasonic element unit for transmitting/receiving ultrasonic waves, a swing mechanism for swinging the ultrasonic element unit, and a detector for detecting the swing motion of the ultrasonic element unit. The detector detects the swing angle and swing origin of the ultrasonic element unit and also detects whether the ultrasonic element unit lies in a positive region or a negative region into which the swing range of the ultrasonic element unit is divided with the swing origin used to fix the boundary. At the time of use of this ultrasonic probe, origin return control for returning the ultrasonic element unit to the swing origin is effected on the basis of the results of detection from the detector.
