Abstract: Disclosed herein are system, method, and computer-readable medium aspects for assessing ablation lesions in realtime. An aspect operates by receiving a first optical measurement data from a first catheter optical port, assigning the first optical measurement data to a first available processing core in a processing unit in order to identify an optical property at a first location of a lesion, and generating a first graphical representation from the optical property at the first location of the lesion. After a predetermined time, the aspect continues to operate by repeating the receiving, assigning, and generating operations for a second optical measurement data using a second available processing core in order to generate a second graphical representation from the optical property at a second location of the lesion. The aspect concludes by displaying the first graphical representation and the second graphical representation on a user interface at a predefined interval.

Abstract: Disclosed herein are system, method, and computer-readable medium aspects for improving the accuracy of an ablation model through synchronization. An aspect operates by activating a catheter energy source, acquiring a catheter energy signal from the catheter energy source, assigning an activation time stamp and deactivation time stamp to the catheter energy signal, and determining a time of ablation based on a time period between the activation time stamp and deactivation time stamp. The aspect continues to operate by acquiring an optical measurement signal from a catheter optical port, assigning an input time stamp and switching time stamp to the optical measurement signal, and processing the optical measurement signal in order to acquire a denaturation result. The aspect concludes by synchronizing the time of ablation and the denaturation result using the time stamps in order to generate a synchronized model and generating an estimated lesion depth from the synchronized model.

Abstract: Described herein are systems, methods for detecting gaps between lesions formed in tissue during ablation. A system includes a catheter that has proximal section, a distal section, and a shaft coupled between the proximal section and the distal section. A plurality of optical fibers are located within the catheter and are coupled to a computing device. The computing device includes a memory and a processor configured to receive, from the optical fibers, optical measurement data of a portion of tissue during or after an ablation, identify one or more optical properties of the portion of tissue by analyzing the optical measurement data, and detect a presence or an absence of a gap between one or more lesions formed in the portion of tissue based on the one or more optical properties.
