Module Description

When we want to register two images, often times, we would like an accurate matching at certain region. For example, in the atrial fibrillation longitudinal study, we want to register the pre-op and post-op images. In particular, we want the matching at the atrium to be emphasized. In such cases, we can use the segmentation of the target region, atrium in the previous example, to aid the registration process. This module is such a segmentation aided registration tool.

Use Cases

  • In the atrial fibrillation longitudinal study, we want to register the pre-op and post-op images. In particular, we want the matching at the atrium to be emphasized.

Tutorials

  • Step 1. Give the input images, including:
    • Fixed grayscale image
    • Segmentation label image for the target region in the fixed image
    • Moving grayscale image
    • Segmentation label image for the target region in the moving image
  • Step 2. Give the output filename.
  • Run
  • There is an optional parameter:
    • Only perform deformable registration locally? Yes by default. The output registered grayscale image will only be around the target region. Uncheck to get the registered moving image in the entire region, but this is VERY SLOW.

Panels and their use

  • Input
    • Fixed grayscale image
    • Segmentation label image for the target region in the fixed image
    • Moving grayscale image
    • Segmentation label image for the target region in the moving image
  • Output
    • Registered moving image
  • Parameter (pptional)
    • Only perform deformable registration locally? Yes by default. The output registered grayscale image will only be around the target region. Uncheck to get the registered moving image in the entire region, but this is VERY SLOW.
