A preparation method of a dual-mode focusing ring array probe and the ring array probe

Abstract

The invention discloses a method for preparing a dual-mode focusing ring array probe and the ring array probe. The method includes: determining the basic parameters of the ring array probe to be prepared, and determining the array element type gate according to the basic parameters Limit value; determine the array element type of the ring array probe to be prepared according to the threshold value of the ring array type; adopt the array element of the array element type, and prepare the ring array probe according to the basic parameters. In the present invention, on the premise that the basic parameters of the ring array probe are determined, the threshold value for determining the type of array element is determined through the basic parameters, and the threshold value is used to determine whether the array element of the ring array probe is a plane array element or a concave surface In this way, different types of array elements are selected according to different basic parameters, so that the ring array probe can have two modes of electronic focus and / or natural focus, so that under the premise of ensuring that the axial resolution remains unchanged, Improve the lateral resolution and receiving sensitivity of the required sound field range.

Description

technical field [0001] The invention relates to the technical field of ring array probes, in particular to a method for preparing a dual-mode focused ring array probe and the ring array probe. Background technique [0002] Ring probes can be focused point-by-point in the beam direction and have high sensitivity, so that depending on the particulars mentioned above, ring array probes can be combined with mechanical scanning to generate 2D and / or 3D imaging of volumetric ultrasound scans. However, due to the limitations of the clinical application of ultrasound and the processing technology of the ring array probe, the number of ring array elements of the ring array probe and the maximum outer diameter of the ring array elements are limited, which makes the ring array not all acquisition in the beam direction The dots are well focused, resulting in poor receiver sensitivity and lateral resolution. Therefore, under the constraints of the number of ring array elements of the ri...
