The primary purpose of this study was to develop a laboratory photonic set-up for characterisation of homogeneity of gel phantoms for calibration of a magnetic resonance. In this system optical coherence tomography allows the detection of micro- and macroscopic heterogeneities of a structure. The set-up was used to perform measurements of agar and agar-carrageenan gels, which are the basis for more complex phantoms for magnetic resonance calibration. Obtained results were compared with magnetic resonance tomography methods used to detect macroscopic spatial differences in composition and heterogeneities in phantoms.
