Three-dimensional multiexcitation magnetoacoustic tomography with magnetic induction.
Magnetoacoustic tomography with magnetic induction (MAT-MI) is a hybrid imaging modality proposed to image electrical conductivity contrast of biological tissue with high spatial resolution. This modality combines magnetic excitations with ultrasound detection through the Lorentz force based coupling mechanism. However, previous studies have shown that MAT-MI method with single type of magnetic...
متن کاملMulti-excitation magnetoacoustic tomography with magnetic induction (MAT-MI)
Magnetoacoustic tomography with magnetic induction (MAT-MI) is an approach proposed to do non-invasive electrical conductivity imaging of biological tissue using magnetic induction and ultrasound measurements. In the present study, based on the analysis of the relationship between the conductivity distribution and the generated MAT-MI acoustic source, we propose a new multi-excitation algorithm...
متن کاملMagnetoacoustic Tomography with Magnetic Stimulation (MAT-MS)
We have proposed a new imaging modality, magnetoacoustic tomography with magnetic stimulation (MAT-MS) to image the electrical impedance distribution. In this paper we report out pilot experimental study. In MAT-MS, the tissue is put in a static magnetic field and a pulsed ( s μ ) magnetic field. The pulsed magnetic field induces eddy current in the tissue. Consequently, the tissue will emit ul...
متن کاملThe Effect of Electrical Anisotropy and Acoustic Inhomogeneity in Magnetoacoustic Tomography with Magnetic Induction
Magnetoacoustic tomography with magnetic induction(MAT-MI) is a noninvasive technology for imaging the distribution of electrical impedance in biological tissue. In the sameple, a time-varying magnetic field induces currents. A static magnetic field interact with the currents to produce a Lorentz force. Consequently, the sample will emit ultrasonic waves by the Lorentz force. The objective of t...
متن کاملImaging biological tissues with electrical conductivity contrast below 1 S m by means of magnetoacoustic tomography with magnetic induction.
Magnetoacoustic tomography with magnetic induction (MAT-MI) is a recently introduced imaging modality for noninvasive electrical impedance imaging, with ultrasound imaging resolution and a contrast reflecting the electrical conductivity properties of tissues. However, previous MAT-MI systems can only image samples that are much more conductive than real human or animal tissues. To image real bi...
