Effect of brain shift on the creation of functional atlases for deep brain stimulation surgeryEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion The effect of brain shift in deep brain stimulation (DBS) surgery has been demonstrated using intra-operative somatotopy recordings as well as stimulation response data. The results not only indicate that considerable brain shift happens before micro-electrode recordings in DBS but also that brain shift affects the creation of accurate functional atlases. Therefore, care must be taken when building and using such atlases of intra-operative data and also when using intra-operative data to validate anatomical atlases.

Forecasting respiratory motion with accurate online support vector regression (SVRpred)Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion This new algorithm is a feasible tool for the prediction of human respiratory motion signals significantly outperforming previous algorithms. The only drawback is the high computational complexity and the resulting slow prediction speed. High performance computers will be needed to use the algorithm in live prediction of signals sampled at a high resolution.

A probabilistic framework for freehand 3D ultrasound reconstruction applied to catheter ablation guidance in the left atriumEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Introduction The catheter ablation procedure is a minimally invasive surgery used to treat atrial fibrillation. Difficulty visualizing the catheter inside the left atrium anatomy has led to lengthy procedure times and limited success rates. In this paper, we present a set of algorithms for reconstructing 3D ultrasound data of the left atrium in real-time, with an emphasis on automatic tissue classification for improved clarity surrounding regions of interest. Methods Using an intracardiac echo (ICE) ultrasound catheter, we collect 2D-ICE images of a left atrium phantom from multipl...
