Combined echo evaluation of the effectiveness of phasing the data with the first echo which mitigates the non-RF related artefact. a) PRF reconstruction affected by artefact without TE1 artefact mitigation, b) PRF reconstruction after the TE1 artefact mitigation which is the non-RF heating related artefacts, c) Difference in temperature between PRF reconstruction without TE1 artefact mitigation and with TE1 artefact mitigation, d) Calibrated from the stabilisation period, e) Artefact mitigation using calibrated artefact from stabilisation period. (The artefact shown in PRF reconstruction is not an RF heating related artefact, and is potentially caused by the laminated print label attached outside of the phantom (see Supplemental Fig. 3).
