In-vivo optical properties spectra across five body locations on ten subjects using time-domain diffuse optics

Year: 2026

Type: data-paper

Abstract: We present a comprehensive dataset of absorption and reduced scattering spectra collected via time-domain diffuse optical spectroscopy in the 610-1110 nm range, across 10 subjects and on 5 different body locations - the upper arm, the radius-ulna region, the abdomen, the forehead, and the calcaneus. The ultrasound images acquired in the same location are included as well, and along with the demographic information shed useful insights on the inter-subject variability. The dataset, openly available in Zenodo, contains the raw data, the meta data, the tools to operate on them, and can be exploited to devise light-based diagnostics or therapeutic techniques, to appreciate biological variability, and also to test different models of photon migration.
