Problems solved by technology

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 points are well focused, resulting in poor receiver sensitivity and lateral resolution

Abstract

The invention discloses a preparation method of a dual-mode focused annular array probe and the annular array probe. The method comprises the steps that basic parameters of the annular array probe needing to be prepared are determined, and an array element type threshold value s determined according to the basic parameters; the array element type of the annular array probe needing to be prepared is determined according to the annular array type threshold value; array elements of the array element type are adopted, and the annular array probe is prepared. On the premise that the basic parameters of the annular array probe are determined, the array element type threshold value is determined according to the basic parameters, the array elements of the annular array probe are planar array elements or concave array elements, and therefore different types of array elements are selected according to different basic parameters so that the annular array probe can have an electron focusing modeand / or a natural focusing mode, and the transverse resolution and receiving sensitivity in a required sound field range are improved on the premise of guaranteeing that the axial resolution is not changed.

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...
