Patent

CA 2406684

-22- This invention relates to an ultrasonic transducer array for non-destructive imaging and inspection of materials, suitable for applications such as bio- medical imaging. According to the invention, the transducer has at least one electrode comprising an array of electrode elements, wherein the elements are not separated by a grooves or kerfs. The grooveiess transducer design simplifies transducer construction and permits very high operating frequencies, and hence very high resolution. In one embodiment suitable for producing real-time high resolution 3-dimension images, the invention provides a hybrid transducer comprising two opposed electrodes, one electrode being a grooveless linear array and the second electrode being a grooved linear phased array.
