【 摘 要 】

Agar hydrogel is largely used in magnetic resonance imaging study as tissue mimicking phantom material for its cost-effectiveness and easy preparation. Spin-spin relaxation time, T2 is one important parameter in Magnetic Resonance Imaging study. However, T2 of agar sample is higher than those of human tissues. The addition of paramagnetic agent such as copper sulphate or CuSO4 had been observed to match T2-value of human tissues. In this study, the effect of CuSO4 on relaxation and mechanical properties of agar is observed.
