Curve Registration
CHAPTER 7: Image Management-ViewStation & Photos and Diagrams
1. Click the Curve Registration check box in the Image Registration window.
2. Draw curves on the verification image in the Image Registration window that correspond
with those on the reference image. Refer Applying Points or Curves on page 195.
Unlike Point registration, you do not have to draw every curve that you see on the
reference image.
3. Click Calculate Shift to open the Isocenter Shifts window. Refer to Figure 47.
Figure 47: Isocenter Shifts Window - Curve Registration
MOSAIQ automatically calculates the offset when you select Curve registration.
4. Click Start Search on the Isocenter Shifts tab to run the matching algorithm. MOSAIQ
automatically matches the curves on the reference and verification images.
Click the Stop Search button to stop the matching algorithm. You can see the shift that
MOSAIQ calculated on the Isocenter Shifts tab. Refer to Figure 48.
