Objective
The objective of this project is to enable gated four-dimensional ultrasound reconstruction in Slicer3.
We have previously written and validated software that performs 4D ultrasound reconstruction from a tracked 2D probe in real-time (Pace et al, SPIE 2009). This allows the user to interact with the reconstructed time series of 3D volumes as they are being acquired and to adjust the acquisition process as necessary. The user-interface for the reconstruction software has been implemented within the Atamai Viewer framework. Here, we would like to port it to be used with Slicer3.
Approach, Plan
We plan to interface the reconstruction software with Slicer3 using the SynchroGrab framework described by (Boisvert et al, MICCAI 2008). A command-line interface and a calibration file will allow the user to specify the reconstruction parameters, the reconstruction will be performed, and the resulting time series of volumes will be transfered to Slicer3 using OpenIGTLink.
Progress
Stay tuned!
