A fully automated software-based T1 and T2 measurement method is proposed for phantom studies to shorten processing time and improve reproducibility. This method was validated on phantom data acquired from 77 doped water samples by comparing with manual measurements. Excellent T1 and T2 agreement was found between the two methods, while the processing time was reduced by thousands of times by the automated method
