Full Title of Project

Key Investigators

• BWH: Andrey Fedorov
• MGH: Greg Sharp, Nadya Shusharina

Objective

• Integrate LANDWARP registration into a B-spline-initialized interactive loadable module. The purpose of this task is to simplify fine-tuning of the deformable registration results, and to simplify interactive registration where automatic methods fail.

Approach, Plan

• Develop a loadable module that would provide an interface for chaining B-spline deformable registration with the landmark-based LANDWARP registration
• The module will encapsulate initialization by B-spline registration using BRAINSFit. The resulting grid of B-spline control points will be automatically displayed over the image to allow the user to adjust the locations of the control points. As the last step, LANDWARP module will be executed as a command line module to produce a dense deformation field given the displacements and the correspondences of the input fiducial points.
