EXAMPLE: MANUAL REGISTRATION BETWEEN 2 VOLUMES FROM 3 SPECIFIC LANDMARKS.

This example is based on 2 volumes (i.e. registration from image_1 to image2) using specific points (i.e. anatomical landmarks). By using the AimsManualRegistration command line, you will obtain a transformation matrix from image_1 to image_2 as a .trm file.

  • For each volume, draw a ROI with exactly 3 regions (each region must contain only 1 voxel) with the same name per region (ie voxel_1, voxel_2, and voxel_3). So, you have the following ROIs: ROI_image_1.arg and ROI_image_2.arg with the structure of each ROI is composed by the regions: voxel_1, voxel_2 and voxel_3.

  • The command line is as follows:

    prompt% AimsManualRegistration -f ROI_image_1.arg -t ROI_image_2.arg -o ROI_image_1_TO_ROI_image_2.trm
    

NOTE: to load a transformation, please refer to The Anatomist getting started guide.
