2008 IGT Project Week Optimal Transseptal Puncture Location for RF ablation

Back to 2008_IGT_Project_Week#Projects

Team: Jayender Jagadeesan, Raul San Jose, Noby Hata

Goals:

- Develop an algorithm to determine the optimal transseptal puncture location for maximum maneuverability of the catheter inside the left atrium.

- Register the optimal location of the transseptal puncture computed on the preoperative CT/MR image to the intracardiac echo image for helping clinicians guide the needle in real time.

Approach:

- Develop a dynamic model for the catheter using differential geometry of curves and continuum mechanics.

- Define the Jacobian operator for the catheter which relates the end-effector velocity to the "joint" velocities.

- Based on the isotropic index defined for robots, we determine the optimal location of the transseptal puncture.

- Develop algorithms to register the septal wall in the preoperative MR/CT image to intraoperative ultrasound image.

Results (to be completed and presented at the end of the week):
