Data set for: Terahertz Time-Domain imaging of feet of diabetic and non-diabetic patients

This respository contains Terahertz Time-Domain imaging dataset of human plantar surface of the feet acquired from type-2 diabetic and non-diabetic volunteers. The measurements were collected in reflection geometry using a fiber-coupled terahertz system and include spatially resolved terahertz waveforms obtained through raster scanning of both feet soles.The dataset comprises raw terahertz signals, and participant metadata, including demographic and clinical information. The data were acquired as part of a previously published clinical study.
