Fast and Automatic Ultrasound Simulation from CT Images

Figure 4

Comparison of simulated ultrasound images using direct simulation and multiscale enhancement method. (a) is the directly simulated ultrasound; (b) is the simulated result with multiscale enhancement. (a1) and (b1) show the magnified details of the rectangle strip in (a) and (b), respectively. (c) shows the intensity distribution in horizontal direction.
