摘要：

This paper presents a new imaging method based on the classical Hall effect (HE), which describes the origin of a detectable voltage from a conductive object moving in a magnetic field, HE images are formed using ultrasound imaging techniques in a magnetic field, These images reflect the electrical properties of the sample, To demonstrate the feasibility of this method, images of plastic and biological samples are collected. The contrast mechanism and signal-to-noise issues are discussed. Since electrical parameters vary widely among tissue types and states, HE imaging may be a useful tool for biological research and medical diagnosis.
