要約(日本語): A unique needle-type GMR sensor is proposed for estimating very low concentration magnetic fluid weight density. The estimation is based on the differential flux density inside and outside a magnetic fluid filled cavity. Experiments using the needle type sensor are performed on agar cavities filled with very low concentration magnetic fluid, simulating actual tumors. Preliminary investigations show that magnetic fluid weight density concentrations as low as 0.03 % can be estimated.
