Dielectric contrast of tumors has received significant interest as a potential means to improve specificity of cancer imaging. Although dielectric property estimation from MR transmit field is a promising approach, the noise inherent in field maps and the reconstruction algorithm may introduce errors. Therefore, we propose a reference aided method to validate data sets, and optimize reconstruction algorithm parameters to improve the process. The process is demonstrated with two reference solutions and adenocarcinoma strains grown in rat models.
