Abstract :
A new imaging method using the classical Hall effect has been developed in the context of diagnostic applications. “Hall effect imaging” (HEI) relies on ultrasonic signal generated by a pulsed current through the sample in a strong magnetic field. Hall effect images reflect the dielectric distribution of the sample. Phantom images have been collected with a single crystal sensor. Since dielectric parameters vary greatly among soft tissues and between normal and pathological states, HEI holds promises for human imaging
