| 1 | Simulation study of the superharmonic field generated from a phase array transducer显示文摘Ultrasound imaging is the most widely used noninvasive medical imaging modality. Its latest elite concept is Superharmonic Imaging which is the most talked-about future of medical diagnostic ultrasound.In this paper,the computational and analytical study for superharmonic field generation from phased array transducer of 16×16 elements is presented. For this,the model preferred,includes the calculation for diffraction effect in frequency domain and nonlinear effect in time domain.The attenuation is included along with the diffraction in frequency domain as well.The comparative analysis of superharmonic field is also carried out with simulated fundamental and second harmonic fields by the same model.Similarly,the comparison with the results from the literature is also reported. | Narendra D Londhe R.S.Anand | 2011 | Chinese Journal of Acoustics2011，30，4： | 2 |
