-
First, a new method of ultrasound - modulated optical tomography with real - time fast fourier transformation ( fft ) is reported to improve the detection sensitivity and snr. by discriminating ultrasound modulated information carried by scattering photons, the tomographic images of the biological tissue simulating media and a buried object are reconstructed with fft spectral intensity
1 、用實時快速fourier變換（ fft ）和聚焦超聲調制的光學層析術以增加探測靈敏度和信噪比，用fft實時地將調制光光信號濾出，用其譜強度重建圖像。
