Three-dimensional ultrasound imaging of the prostate

Prostate Boundary Detection From Ultrasonographic Images

“…In the last few years, technology has progressed to make 3D ultrasonographic imaging a viable tool. Previous reports [50][51][52] have shown that 3D ultrasonography has advantages over conventional techniques and that it will play an increasingly important role in prostate disease diagnosis and treatment. Although from sequential crosssectional 2D boundaries we can reconstruct a 3D prostate surface, 14,15,18,19 those algorithms, which would be able to take advantage of 3D information, 26,27 would be more robust and accurate.…”

“…Moreover, it is difficult to place the 2D image plane at a particular location within an organ, and even more difficult to find the same location again later. To overcome these limitations, 3D transrectal ultrasound of the prostate has been developed [13,14,15]. Consequently, 3D prostate surface detection techniques are attracting more and more attentions from the image processing community.…”

“…From the point-to-surface distance defined in Eq. 5.11, we can define a mean error d m between two surfaces S and S : 14) where |S| denotes the area of S. For the same reason of asymmetry as addressed before, we need to define a symmetrical version of the mean error as the mean…”

“…In the last few years, technology has progressed to make 3D ultrasound imaging an economically viable tool. Reports in [15,14,84] have shown that 3D ultrasound has advantages over conventional 2D techniques, and that it will play an increasingly important role in prostate disease treatments. Although from sequential cross-sectional 2D boundaries we can reconstruct a 3D prostate surface [19,20,23,24], as reported in [31,85], algorithms that could take advantage of 3D information would be more robust and accurate.…”
