Fast and Automatic Ultrasound Simulation from CT Images

Figure 3

Comparison of different ultrasound simulation methods. The first row shows volume rendering of the original CT image, the extracted vascular structure, and the enhanced image, respectively. The second row shows selected liver section in transverse direction of the original CT image, the extracted vascular structure, and the enhanced image, respectively. (a3) and (c3) in the third row show simulated results of (a2) and (c2), respectively, while the middle image in the third row shows two magnified regions of interest corresponding to the same locations in (a2) and (c2).
