We have developed the method for improvement in the receiver dynamic range and signal processing technique of image reconstruction in demodulated direct current voltage-based microwave CT (DC-MCT). By using standard signal generator with the low phase noise and phase synchronization of signal source, the reconstructed amplitude- and phase-images were obtained. Improvement in receiver dynamic range was attempted on the distributed system gains to radio- and low-frequencies. By removing unwanted components of the received signal, the receiver dynamic range was expanded. Two methods for removing unwanted components from the received signal were attempted by using time domain filters to remove all receiver noises from the measurement data. By removing unwanted components, the reconstructed definite tumor images of the breast-and biological-phantoms were obtained. At the result, this paper shows usefulness of the new method that improves the receiver dynamic range and reconstructed images.
