2008 IGT Project Week Dynamic control of the MRI acquisition
Back to 2008_IGT_Project_Week#Projects
Team:Nathan McDannold, Ben Schwartz, Scott Hoge
Goals: Dynamic control of the MRI acquisition based on US-based signals. This would be to apply existing technologies developed for IGT such as optical-based tracking of a biopsy or ablation probe.
- want to move FUS treatments to dynamic target (liver, kidney)
- use ultrasound navigators
- how many sensors does one need?
- different ways to manipulate the MR scan
Results (to be completed and presented at the end of the week):
Over the course of this week, we
- discussed new algorithmic approaches to fast US registration, based on recent research in content-based image retrieval, dimensionality reduction, and sparse coding
- determined a way to connect the Realtime Data Server, MRMail, RTHawk, DARTS, 3D Slicer, OpenIGTLink, and other components into a system that is capable of altering image acquisition parameters with sufficiently low latency to allow navigation from US
- considered extensions of this concept to dynamic control of stereotactic radiotherapy and CT based on US navigation
- began packaging work on 3D Slicer to improve its integration with standard Linux operating systems, so that it may be included as a standard component.
