In order to assess fatigue crack propagation, one of the most-used laws is due to Elber. This involves, however, accurate measurement of the opening load of the crack which is closed at its tip. We propose a new ultrasonic method based on wave diffraction by the crack tip and a record of the echodyn

## Abstract ## Purpose. To evaluate the accuracy and reliability of two 3‐dimensional (3D) ultrasound imaging and measurement techniques in volume measurements using custom‐made phantoms. ## Methods. A total of 20 phantoms with irregular‐shaped test objects of known volume (2–9.7 ml) were constr
