Problems solved by technology

Even so, good contacts are often not available
For example, when ultrasonically treating a fractured limb, traditional ultrasound transducer arrays do not conform well to the surface of the limb
[0003] Furthermore, in most cases, geometrical changes in body parts are unacceptable for ultrasound imaging or ultrasound therapy using conventional ultrasound transducers
For example, in the process of applying a traditional ultrasonic transducer to image a body part without deformation in three-dimensional (3D) stereoscopic shape, any geometric change in the body part is not allowed to avoid the ultrasonic imaging effect caused by the geometric change. bad

Embodiment Construction

[0028]As mentioned above, the present invention provides a flexible ultrasonic transducer array, which consists of not less than two ultrasonic transducer units arranged in an array form in or on the surface of a flexible layer medium; wherein, the array form can be It is in the form of a one-dimensional array as shown in Figure 1-A, or in the form of a two-dimensional array as shown in Figure 1-B. In short, the number and array form of the ultrasonic transducer units (110) can be selected at will according to actual needs; and the flexible ultrasonic transducer array can fit ultrasonic treatment / ultrasound imaging objects with different surface shapes, Thereby, a good ultrasonic treatment / imaging effect that cannot be achieved in the prior art can be obtained; and, by adding a shape scanner or a shape sensor, it can be used to monitor the surface shape information of the flexible ultrasonic transducer array before or during its operation, and According to the surface shape in...

Abstract

The invention provides a flexible ultrasonic transducer array, which comprises at least two ultrasonic transducer units and flexible layer medium. The ultrasonic transducer is arranged in the flexible layer medium or on the surface of the flexible layer medium in the form of array; an ultrasonic device comprises at least two ultrasonic transducer units, an ultrasonic emitter / ultrasonic transceiver, ultrasonic coupling medium, a microprocessor and flexible layer medium, and the ultrasonic transducer unit is arranged in or on the surface of flexible layer medium in the form of array to form flexible ultrasonic transducer array; ultrasonic transducer array and the ultrasonic device also comprises a shape scanner / shape sensor which is used for measuring superficial shape information of flexible ultrasonic transducer array and helping ultrasonic beam focus and orient. As flexible ultrasonic transducer array can attach to body position with different superficial shapes, the technical proposal provided by the invention can realize the effect of ultrasonic treatment / ultrasonic imaging which can be realized by the prior art.

Description

technical field [0001] The present invention relates to ultrasonic transducers, in particular to ultrasonic transducer arrays; more specifically, the present invention relates to shape-variable flexible ultrasonic transducer arrays, and the flexible ultrasonic transducer arrays are used in ultrasonic therapy and ultrasonic imaging, etc. Applied devices in the medical field. Background technique [0002] Traditional ultrasonic transducer arrays generally have two shapes, either flat or curved; and their shape is always fixed, and the relative position and direction of each component transducer are always fixed. Change. When a body part with a curved shape is required for ultrasound imaging or ultrasound therapy, in order to obtain good contact, it is necessary to press the conventional ultrasound transducer array tightly to the tissue surface of the body part. Even so, good contact is often not available. For example, when ultrasonically treating a fractured limb, traditio...
