摘要：
An ultrasonic imaging technique for differentiating the distribution of scatterers within a tissue comprises a correcting and an imaging procedure. The correcting procedure includes steps of obtaining ultrasonic backscattered signals from a standard phantom, compensating and demodulating the signals into an envelope image, calculating the parameter m and m, selecting a window to calculate parameter mw in each location of the envelope image and mw, if mw≠ m then increase the size of the window to repeat the steps above, and when mw= m, it is the optimal size of the window. The imaging procedure includes steps of obtaining ultrasonic backscattered signals from a target tissue, compensating and demodulating the signals into an envelope image, calculating mw in each location to form a mw matrix, and presenting the matrix by utilizing pseudocolors.
