Embodiment 1

[0037] Such as Figure 1 to Figure 9 It is an embodiment of a surface-focused ultrasonic transducer array, including 64 array elements 1; each array element 1 includes a frame 2 and a crystal layer 3 fixedly arranged on the frame 2, and the crystal layer 3 is concave toward the frame 2 A concave arc surface structure capable of line focusing; it also includes a control device electrically connected to the crystal layer 3 of each array element 1, and the control device controls each array element 1 to work independently.

[0038] Such as Figure 9As shown, the control device in this embodiment is a multi-channel controller, and the multi-channel controller has independent channels whose number is greater than or equal to 64, and each independent channel controls each array element 1 correspondingly. This setting is to enable the control device to independently control each array element 1, and separately excite the crystal layer 3 of each array element 1 to emit ultrasonic wav...

Embodiment 2

[0046] Such as Figure 10 , Figure 11 It is an embodiment of a surface-focused ultrasonic transducer array.

[0047] The difference between this embodiment and Embodiment 1 lies only in the array form of array elements 1 .

[0048] Such as Figure 10 As shown, the array form of the array elements 1 in this embodiment is a hollow rectangular array.

Embodiment 3

[0050] Such as Figure 12 It is an embodiment of a surface-focused ultrasonic transducer array.

[0051] The difference between this embodiment and embodiment 1 or embodiment 2 lies in the control device.

[0052] Such as Figure 12 As shown, the control device in this embodiment is a plurality of independent controllers, and each controller is connected to each array element 1 to realize independent control of the array element 1 .

Abstract

The invention relates to the technical field of transducers, in particular to a surface-focusing ultrasonic transducer array and a transducer thereof. The surface-focusing ultrasonic transducer arraycomprises: a plurality of array elements, wherein each array element comprises a frame and a crystal layer fixedly arranged on the frame, and the crystal layer is of a concave cambered surface structure which is concave towards the frame and can be linearly focused; and a control device, which is electrically connected with the crystal layer of each array element and controls each array element towork independently. According to the invention, a plurality of hollow semi-cylindrical transducers capable of realizing linear focusing are arranged to form the transducer array and are combined to form a planar focusing area, so a focusing volume is increased, and treatment time is reduced; and in addition, each array element is controlled by the control device to work independently, so a part of the array elements work and a part of the array elements are closed to form a required focusing volume and a required focusing shape, and human tissues which do not need to be treated are avoided.

Description

technical field [0001] The present invention relates to the technical field of transducers, in particular to a surface-focused ultrasonic transducer array and a transducer thereof. Background technique [0002] Existing focused ultrasound transducers are generally composed of a single spherical transducer, which is directly focused on the geometric focus of the spherical transducer. The position is relatively fixed, and the position of the focus can only be changed by mechanical movement. Flexibility Poor; or it is a phased array composed of multiple ultrasonic transducer array elements. By adjusting the phase and amplitude of each array element, the focal length and focus position can be electronically adjusted, but this adjustment method is not suitable for complex human body The structure is still not flexible enough. [0003] Chinese patent CN105228699A discloses a line-focused ultrasonic transducer and a high-intensity line-focused ultrasonic generating device includin...
