Abstract
An electrical impedance tomography apparatus () and method. The electrical impedance tomography apparatus () consists of a sensing module (), a data acquisition module (), a communication module (), a data processing module (), an image display module () and a power supply module (). The electrical impedance tomography apparatus () is applicable to medical imaging, can employ an in vivo electrode to perform multi-frequency-one-time excitation and measurement on a biological tissue under test and use a measured complex voltage signal to perform three-dimensional image reconstruction, and can simultaneously display ventilation and perfusion images in real time, thereby increasing an amount of acquired data, increasing the speed of data acquisition, increasing the sensitivity of a measurement signal to the conductivity of an in vivo tissue, and facilitating image analysis and comparison, disease detection and diagnosis.
