Volume-Rendering-Based Interactive 3D Measurement for Quantitative Analysis of 3D Medical Images
Figure 9
Interactive 3D measurement of the tumor in the brain MR image. First, the tumor is segmented from the MR image using a region growing method automatically. Then, the tumor model and the original MR image are put in the same rendering environment for interactive 3D measurement. (a) Area measurement (surface model of the tumor is used and rendered by surface rendering). (b) Distance measurement (volume model of the tumor is used and rendered by ray casting). (c) Angle measurement (surface model of the tumor is used and rendered by surface rendering).
