Abstract: Electrical Impedance Tomography is used to image the cross-sectional conductivity of an object. It is clinically used for high-frame-rate imaging of lung ventilation. Most current systems use very limited current injection wave-forms and patterns. We have developed a flexible system for researching alternatives. This paper covers our current supply module's design and characterisation. We tested the input filtering, Bandwidth, and parasitic capacitance. The imput fitering functioned similarly to the simulation of the design. However, the bandwich was limited to approximately 1 MHz instead of the desired 10 MHz due to excessive parasitic capacitance. We proposed points to redesign that should reduce the capacitance by a factor of 10 and correspondingly increase dandwidth tenfold to 10 MHz.
