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 pathological states, HE imaging may be a useful tool for biological research and medical diagnosis.
本文提出了一种基于经典霍尔效应(HE)的新成像方法,该效应描述了导电物体在磁场中移动时可检测电压的起源。霍尔效应图像是在磁场中使用超声成像技术形成的。这些图像反映了样品的电学性质。为了证明该方法的可行性,收集了塑料和生物样品的图像。讨论了对比机制和信噪比问题。由于不同组织类型和病理状态下的电学参数差异很大,霍尔效应成像可能是生物研究和医学诊断的有用工具。
