## Abstract A new tissueβequivalent MRI phantom based on carrageenan gel was developed. Carrageenan gel is an ideal solidifying agent for making large, strong phantoms in a wide variety of shapes. GdCl~3~ was added as a __T__~1~ modifier and agarose as a __T__~2~ modifier. The relaxation times of a
Pbantoms for evaluation of nuclear magnetic resonance (NMR) imaging systems were made from water-based agarose gels, according to a standard procedure herein described. Copper sulfate (CUSO,) was included in tbe gels to further affect tbeir proton relaxation ckamcteristics. Tbe proton relaxation rat
