BACKGROUND AND SIGNIFICANCE
Acquisition of three-dimensional (3D) ultrasound images is an essential technique for various image-guided interventional procedures. The 3D volumes are constructed from a set of image slices acquired by an ultrasound transducer equipped with a position tracking device.
The limitation of the method is that it is not feasible to acquire so many image slices that would completely fill a high-resolution volume, but there are "holes" in the volume between the image slices.
- Review methods that have been proposed for filling holes in volumetric ultrasound images
- Implement a chosen hole-filling algorithm (preferably in C++, but also acceptable in Matlab)
- Test and optimize the algorithm
