This dataset provides the open-source data organized, pre-processed and cleaned by the authors for the Journal of Biophotonics article, "Robust, High-Density Lesion Mapping in the Left Atrium with Near-Infrared Spectroscopy". The dataset includes optical parameters extracted from the acquired spectrums of ex-vivo swine left atrium using catheter-based near infrared spectroscopy (NIRS) within blood and phosphate-buffered saline (PBS), respectively. A random forest model was applied and the equivalence of predicted lesion probability maps between PBS and blood were assessed. The work illustrate the robustness of optical parameters in blood and without perpendicular contact, confirming their capability to provide useful feedback in-vivo.
