Microwave-Based Colonoscopy: Preclinical Evaluation in an Ex Vivo Human Colon Model

Figure 5

Correlation with the evolution of the maximum amplitude of each successive frame obtained with microwave-based colonoscopy (bottom) and the location of the lesion indicated by the arrows (top). Lower amplitudes around 0.2 are typical of healthy mucosa areas, while neoplastic lesions show high amplitudes close to 1.
