摘要: This ultrasound imspection method using the Born approximation simplifies problem of characterizing 3-dimensional flaws general shape by reducing it to a series 2-dimensional tomographic image reconstructions. The reconstructed images represent projections or shadows flaw characteristic function which specifies flaw. Each projection is independently well developed computerized tomography techniques. If flow not too irregular fine details are interest, only few these needed. from through 3-D reconstruction process.
