Embodiment 1

[0037] figure 1 is a block diagram showing an example of the configuration of an ultrasonic diagnostic apparatus according to Embodiment 1 of the present invention. figure 1 The ultrasonic diagnostic apparatus shown in will also be used in the various embodiments described below.

[0038] exist figure 1 Among them, the ultrasonic diagnostic apparatus according to the present embodiment includes: an ultrasonic transceiver 1 having a plurality of transceiver elements 2 arranged in an array, the transceiver elements 2 transmit ultrasonic beams into the living body, and echo ultrasonic waves from tissues in the living body converted into electrical signals. Each transceiver element 2 is excited by a transmit pulse provided by the transmit / receive device 8 . The transmission / reception device 8 is controlled to provide transmission pulses with different phases to some or all of the transceiver elements 2 arranged in the ultrasonic transceiver 1, so that the transmission pulses...

Embodiment 2

[0053] Next, refer to the attached figure 1 Embodiment 2 of the present invention is described in detail with Embodiment 1.

[0054] Generally, the wobble scan is mostly performed as a reciprocating scan. The purpose of using this method is to form a three-dimensional image in more real time. Also in this case, even when the count value provided by the encoder counter 7 is equal on the forward path of the wobble scan and on its return path, the actual wobble scan angle is often different, which is In addition to the problems mentioned above, another problem arises from the mechanical scanning method.

[0055] This is mainly caused by the rotating shaft connecting the transceiver swing motor 5 and the rotation transmission mechanism of the ultrasonic transceiver 1 . For example, in a rotary transmission mechanism using gears, when the gears are rotated forward and backward, the angle of rotation of the driven gear relative to the rotation angle of the motor shaft is differe...

Embodiment 3

[0059] Next, refer to the attached figure 2 to 6 describe in detail an ultrasonic diagnostic apparatus as Embodiment 3 of the present invention which forms a more accurate three-dimensional image using the ultrasonic probe 13 including the above-mentioned encoder correction ROM 9 and the like.

[0060] In the encoder correction ROM 9 of the ultrasonic diagnostic apparatus according to the present embodiment, the image 3 The correction value shown is 31. exist image 3 Among them, the straight line 30 represents the situation that the swing scanning angle of the ultrasonic transceiver 1 corresponding to the count value of the encoder counter 7 is an ideal value, and wherein the encoder counter 7 is an addition counter using a rotary encoder 4, and the rotary encoder 4 transmits and receives N A-pulses are generated during one revolution of the rotating shaft of the swing motor 5, and one Z-pulse is generated when the angle of the rotating shaft is 0 degrees. In addition, t...

Abstract

There is provided an excellent ultrasonographic device capable of building a three-dimensional image at a spatially correct position not affected by an ultrasonic probe used and realizing it without lowering the treatment productivity. The ultrasonic probe includes an ultrasonic oscillator, a rotation transmission mechanism, a rotary encoder, an oscillator swivel motor, and an encoder correction ROM which are built in the probe The encoder correction ROM stores in advance a swivel scan angle of the actual ultrasonic oscillator for each count value obtained by counting the pulses from the rotary encoder. Three-dimensional image processing means builds a three-dimensional image of the main cross section scan surface in the actual swivel scan angle direction while correcting the encoder count value from an encoder counter according to the content of the encoder correction ROM read out via main control means.

Description

field of invention [0001] The present invention relates to an ultrasonic probe whose purpose is to obtain three-dimensional echo data by receiving ultrasonic echoes generated by the reflection of ultrasonic beams emitted to tissues in living bodies etc. The present invention relates to and relates to An ultrasonic diagnostic device using the ultrasonic probe. Background technique [0002] Usually, as the user cares Figure three An ultrasonic sensor for obtaining three-dimensional data in an ultrasonic diagnostic apparatus for displaying the condition of living tissue three-dimensionally, an ultrasonic probe including an ultrasonic transducer for scanning an ultrasonic beam configured so as to mechanically oscillate (swing) the ultrasonic transceiver to perform swing scanning in a direction intersecting with the beam scanning direction (for example, see JP3(1991)-184532 A). By simultaneously performing ultrasonic beam scanning (hereinafter referred to as Principal cross-sec...
