Transesophageal 2D ultrasound to 3D computed tomography registration for the guidance of a cardiac arrhythmia therapy.

Transesophageal 2D ultrasound to 3D computed tomography registration for the guidance of a cardiac arrhythmia therapy. Phys Med Biol. 2018 Jul 11;: Authors: Sandoval Z, Castro M, Alirezaie J, Bessière F, Lafon C, Dillenseger JL Abstract The work aims at developing a new image-processing method to improve the guidance of transesophageal HIFU atrial fibrillation therapy. Our proposal is a novel registration approach that aligns intraoperative 2D ultrasound with preoperative 3D-CT information. This approach takes advantage of the anatomical constraints imposed at the transesophageal HIFU probe to simplify the registration process. Our proposed method has been evaluated on a physical phantom and on real clinical data.&#13. PMID: 29992909 [PubMed - as supplied by publisher]
