Abstract
Described herein are systems and methods for performing optical signal analysis for tissue ablation using a catheter having viewports. A method includes transmitting illumination toward a target tissue via the viewport. The method also includes receiving, at a first viewport, a first scattered illumination from the target tissue and generating a first measurement signal based on the first scattered illumination. The method also includes receiving, at the first viewport, a second scattered illumination from the target tissue after the receiving of the first scattered illumination and generating a second measurement signal based on the second scattered illumination. The method also includes determining whether the viewport is in contact with the target tissue based on a first difference among the plurality of optical measurements meeting or crossing a first threshold value, wherein the first difference comprises a difference between the first and second measurement signals.
