[0050] refer to Figure 4 , a first embodiment of an alignment method for a multi-element ultrasonic transducer, comprising the following steps:

[0051] Step S400, determining the first array element and the second array element symmetrically arranged in the direction perpendicular to the rotation axis of the first alignment direction of the multi-element ultrasonic transducer;

[0052] The multi-element ultrasonic transducer of this embodiment includes a plurality of array elements evenly distributed on a probe, and the second alignment direction that requires alignment includes but not limited to the displacement direction facing the reflection target, and the ultrasonic The straight line on the signal emitting surface is the rotation direction of the rotation axis. When the multi-element ultrasonic transducer is a convex transducer array, alignment needs to be performed in multiple degrees of freedom. In this embodiment, a planar transducer array is taken as an example f...

Abstract

The invention discloses an alignment method for a multi-array-element ultrasonic transducer. The method comprises the steps: determining a first array element and a second array element, which are symmetrically arranged along a direction vertical to a rotation axis of a first alignment direction, of the multi-array-element ultrasonic transducer; successively gating the first array element and thesecond array element, scanning a reflection target by using gated array elements, and determining pose adjusting parameters of a probe according to arrival time t of echo signals reflected from the reflection target; and adjusting a pose of the probe according to the pose adjusting parameters. The invention further discloses an alignment device and system for the multi-array-element ultrasonic transducer and a storage medium. According to the alignment method, device and system for the multi-array-element ultrasonic transducer and the storage medium, alignment of the multi-array-element ultrasonic transducer can be achieved without manual participation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an alignment method, device, system and storage medium of a multi-element ultrasonic transducer. Background technique [0002] Ultrasound probe is the most critical acoustic component in medical ultrasound imaging system. It is generally composed of multiple array elements, and each array element is a separate ultrasonic transducer device. These array elements are evenly arranged in a plane or convex shape. The evaluation of the use characteristics of the ultrasonic transducer is mainly realized by processing the echo measurement data and the measurement data of the sound field distribution characteristics. When the ultrasonic transducer performs echo measurement, it is necessary to align the ultrasonic transducer so that the best measurement position can be found to make the measurement result more accurate. However, in the existing echo measurement system, the alignmen...
