Post-processing algorithm on images of electrical impedance tomography / 医疗卫生装备

ABSTRACT

Objective To study the image processing methods of electrical impedance tomography(EIT) in order to improve the display quality.Methods Evaluate the conductivity of the nodes using the conductivity of the adjacent triangle elements.The conductivity of any point in one triangle element was calculated according to the conductivity of 3 vertexes of the element by 2D linear interpolation method.Results The original blocky images of electrical impedance tomography by the triangle elements can be transformed into smoothing images.Conclusion The visual quality of the images is improved greatly.The image processing method is adaptive to all kinds of images of electrical impedance tomography based on triangle element.
