Objective

We are working on a 3D ultrasound module in Slicer3, with the goal of creating a module that can

• reconstruct 3D ultrasound volumes from multiple tracked 2D images
• reconstruct 4D ultrasound volumes from multiple tracked 2D images with ECG-gating
• reconstruct panoramic 3D ultrasound volumes from multiple tracked 3D images

on a wide variety of ultrasound scanners

Approach, Plan

3D ultrasound volumes can be created from 2D ultrasound images by acquiring multiple 2D images while tracking the probe. The tracking information is used to insert the images in the correct position and orientation within the 3D volume. A time series of 3D ultrasound volumes (4D US) can be created by incorporating ECG-gating: the 2D ultrasound images are inserted into the correct volume using the ECG information. Finally, panoramic 3D ultrasound volumes can also be built up from smaller 3D ultrasound volumes by simply tracking the probe.

During the project week, David will work with Junichi and Noby to interface OpenIGTLink with the freehand 3D reconstruction code. Danielle will work with David to fix up the last bugs in the freehand 3D reconstruction code and to add the ECG-gating functionality.
