This Excel sheet contains perfusion measurements acquired using Multispectral Optoacoustic Tomography (MSOT) from a cohort of 26 patients undergoing lower extremity revascularization. Measurements were taken at three time points: before the procedure (pre), immediately after the procedure (post), and before hospital discharge (disch). For each patient (identified by a pseudonym in the leftmost column), multiple oxygenation-related parameters were recorded at various wavelengths, targeting three anatomical regions of interest: Tibialis Anterior Muscle – Proximal (TAP), Tibialis Anterior Muscle – Medial (TAM), and Flexor Hallucis Brevis Muscle (FH).
