We showed the alternative approach to quantifying
magnetic moment, susceptibility and cross-sectional area
of veins in human without any a priori information. By
summing up MR signals surrounding the object, the
magnetic moment, susceptibility and the cross-sectional
area of the object can be solved. Here, we tackled three
practical issues-low signal to noise ratio inside the
object, local background field and the cylindrical
object at the low orientation to the main field. The
results of the susceptibility in veins agree with the
recent published papers.
