Figure 2From: Theory, simulation and experimental results of the acoustic detection of magnetization changes in superparamagnetic iron oxide Resolution-determining terms in magnetic and acoustic MPI. The individual components of equation 3 are displayed as function of the product of particle parameters and magnetic field Saturation is reached for much lower fields in the acoustic case (bold curve) as in the magnetic L(αB) case. A comparison of the acoustic with a magnetic curve assuming doubled α (dotted line) indicates more than twice the resolution.Back to article page
