Method to build a high bandwidth, low crosstalk, low EM noise transducer |
摘要 |
An ultrasound transducer array (250) in which the piezoelectric layer (256) and the matching layer(s) (258) have different sub-dicing. In one embodiment, the piezoelectric layer (256) is diced only once and the matching layer(s) (258) is diced more than once. A resulting transducer shows improved bandwidth, crosstalk and noise performance.
