摘要： A wave motion analysis device 100 that detects a defect of an inspection object on the basis of a reflection wave obtained from the inspection object, and includes a multiple reflection area extraction unit 106 that acquires tomographic data generated on the basis of the reflection wave and extracts, from the tomographic data, a multiple reflection area corresponding to a depth range deeper than a depth at which a real image of the inspection object is able to be detected and being an area in which a multiple reflection signal is able to be mainly detected, and a detection unit 107 that detects a multiple reflection image corresponding to the defect of the inspection object from the extracted multiple reflection area.

摘要： A beamforming method includes: generating (S21) a main beam signal by performing, with a focus on a first region, a delay and sum operation on receiving echo signals; generating (S22) a sub beam signal which has a low sensitivity to ultrasound signals reflected off the first region; and generating (S23) a narrow beam signal by (i) calculating a coefficient for narrowing an angle of the main beam signal, and (ii) multiplying the main beam signal by the coefficient, wherein in the generating (S22) of a sub beam signal, the sub beam signal is generated using a differential signal that is a difference between two beam signals each of which is generated by performing a delay and sum operation on the receiving echo signals, with a focus on a corresponding one of two regions of a subject which are different from the first region and are different from each other.
