Method for producing ultrasound image of test object e.g. rotor blade, involves generating measurement matrix by assigning amplitude sum from measurement signal sum to voxels based on sound propagation times, to create image

摘要

The correlated ultrasonic signals of ultrasonic transducer elements (U-kl) on test object (50) are emitted corresponding to respective delay times, for forming a focus area (FB1-nm) by interference in object. A measurement signal sum is calculated by summation of the measurement signals received from focus area along with delay times. A measurement matrix is generated by assigning amplitude sum from measurement signal sum to voxels (V1-hij) based on sound propagation times between voxels and sound entry point. The ultrasound image is created using measurement matrix. An independent claim is included for a device for producing ultrasound image of test volume in test object.
