The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The terms to which the present invention relates will be explained first:
an ultrasonic transducer: refers to an instrument for transmitting ultrasonic waves and receiving echo signals reflected by an object to be imaged.
Referring to fig. 1, a schematic diagram of a prior art according to an embodiment of the present invention is shown. When an object to be imaged needs to be scanned, the linear ultrasonic transducer array 4 needs to be adjusted to an initial angle, a first picture is obtained by scanning, then the linear ultrasonic transducer array 4 is adjusted to a second angle, a second picture is obtained by scanning, and so on, a plurality of pictures are obtained, and then the plurality of pictures are integrated to form a required three-dimensional image. However, in the prior art, during the imaging process, the object to be imaged needs to be scanned angle by angle, and only one plane is scanned at a time, so that the imaging efficiency is low.
In view of the above problem, the present invention provides a two-dimensional ultrasound transducer array for ultrasound imaging, referring to fig. 2, including a plurality of ultrasound transducers 11, the plurality of ultrasound transducers 11 forming a plurality of sets of two-dimensional scanning arrays 1, each set of two-dimensional scanning array 1 including a plurality of ultrasound transducers 11, the plurality of two-dimensional scanning arrays 1 being configured to acquire two-dimensional images of an object to be imaged at a plurality of angles.
It can be understood that the scheme has a plurality of groups of ultrasonic transducers 11, each group of ultrasonic transducers 11 includes a plurality of ultrasonic transducers 11, that is, the plurality of groups of ultrasonic transducers 11 cover the scanning range, and simultaneously scan is realized to obtain a plurality of images, thereby improving the imaging efficiency.
In some embodiments, two sets of two-dimensional scanning arrays 1 may be provided, and the two sets of two-dimensional scanning arrays 1 are uniformly spaced and circumferentially distributed on the outer surface of the diffusion-shaped carrier 2. In other embodiments, there may be more than two sets of the two-dimensional scanning arrays 1, and the multiple sets of the two-dimensional scanning arrays 1 are circumferentially distributed on the outer surface of the diffusion-shaped carrier 2 at even intervals.
For example, if the scanning range required to be scanned is 120 °, and the scanning range for each group of ultrasound transducers 11 is 20 °, 6 groups of ultrasound transducers 11 may be provided to cover the scanning range of 120 °, and 6 pictures may be acquired at a time. In the prior art, a group of ultrasonic transducers 11 needs to be driven 6 times by the device to obtain 6 pictures, so that the imaging efficiency is low.
In some embodiments, in order to implement the diffusion of the scanning range of the multiple sets of ultrasonic transducers 11, each set of two-dimensional scanning arrays 1 may be disposed parallel to each other and uniformly and circumferentially distributed on the outer surface of the diffusion-shaped carrier 2, wherein the area of the outer surface of the diffusion-shaped carrier 2 is larger than that of the inner surface thereof.
It is understood that when the plurality of sets of ultrasonic transducers 11 are circumferentially arranged in parallel on the outer surface of the diffusion-shaped carrier 2, the scanning range thereof is diffused, so that the range to be scanned can be covered by the plurality of sets of ultrasonic transducers 11.
Illustratively, as shown in fig. 2, the diffusion-shaped carrier 2 may include an arc-shaped shadow mask, and the plurality of two-dimensional scanning arrays 1 are uniformly and circumferentially distributed on the outer surface of the arc-shaped shadow mask. It will be appreciated that when the two-dimensional scan arrays 1 are circumferentially arranged on the outer surface of the arc-shaped mask, the scan direction is divergent, for example, the scan direction of each two-dimensional scan array 1 is 20 °, and when 3 sets of two-dimensional scan arrays 1 are provided, the scan range of 60 ° at the maximum can be covered by the separation arrangement.
As another example, as shown in fig. 3, the diffusion-shaped carrier 2 includes a cylindrical shadow mask, and a plurality of two-dimensional scanning arrays 1 are uniformly distributed on an outer surface of the cylindrical shadow mask. It will be appreciated that when the two-dimensional scan arrays 1 are circumferentially arranged on the outer surface of the cylindrical mask, the scanning directions are divergent, for example, the scanning direction of each two-dimensional scan array 1 is 20 °, and when 3 sets of two-dimensional scan arrays 1 are provided, a scanning range of 60 ° at most can be covered by the spaced arrangement.
In the embodiment, the multiple groups of two-dimensional scanning arrays 1 are uniformly distributed on the outer surface of the diffusion-shaped carrier 2, for example, the carrier can be in a cylindrical shape, an arc shape, and the like, so that the scanning directions of the multiple groups of two-dimensional scanning arrays 1 are in a divergent state, thereby covering a larger scanning range, images at multiple angles can be scanned without rotating the angle of the two-dimensional scanning arrays 1 under a general condition, namely, two-dimensional images at multiple angles are obtained, and the spatial position of the two-dimensional scanning arrays 1 corresponding to the two-dimensional images is obtained, then, the three-dimensional image of an object to be imaged is obtained by combining the two-dimensional images and the spatial position, so that real-time imaging is realized, a linear ultrasonic transducer array is not required to be driven, two-dimensional ultrasonic imaging is sequentially performed on each sector at different angles, namely, a plane at one angle is not required, the imaging efficiency is obviously improved.
Referring to fig. 4, in practical applications, the scanning directions of a plurality of sets of two-dimensional scanning arrays 1 may need to be adjusted, so that the diffusion-shaped carrier 2 of the present solution is connected to the positioning device, and the positioning device drives the diffusion-shaped carrier 2 to rotate, so as to adjust the scanning direction of the two-dimensional scanning arrays 1 on the diffusion-shaped carrier 2, and complete scanning of an object to be imaged is completed.
It can be understood that, in the prior art, because the linear ultrasonic transducer array is used, when an object to be scanned is scanned, the linear ultrasonic transducer array needs to be rotated in a large range to complete the whole scanning operation, and in order to scan each angle, the linear ultrasonic transducer array needs to be driven in a large range by a relevant device, and a large system positioning error is introduced in the driving process, so that the imaging quality is reduced. The invention is provided with a plurality of groups of two-dimensional scanning arrays 1, each group of two-dimensional scanning arrays 1 divides the scanning range, and when the angle is adjusted, only a positioning device is needed to control the diffusion-shaped carrier 2 to rotate by a small range of angle, thereby avoiding the error caused by rotating the two-dimensional scanning arrays 1 by a large range of angle and ensuring the imaging quality.
Specifically, the positioning device includes a rotator 3, the diffusion-shaped carrier 2 is connected to a rotating disc 31 of the rotator 3, the rotator 3 may be, for example, a stepping motor, an output shaft of the stepping motor may be provided with the rotating disc 31, and when the stepping motor rotates, the rotating disc 31 rotates along with the stepping motor, so as to drive the diffusion-shaped carrier 2 to rotate, and thus, the adjustment of the scanning direction of the two-dimensional scanning array 1 is achieved.
