From: Near Field Breast Tumor Detection Using Ultra-Narrow Band Probe with Machine Learning Techniques
Experiment results of a chicken breast with an without an embedded metallic sphere of size 9 mm for all the horizontal scans (showing in Fig. 6(a)) and a stand-off distance of 5 mm (showing in Fig. 6(b)). The response of the probe was extracted and analyzed for (a) the magnitude of S11, (b) the magnitude of S11 using PCA, (c) the phase of S11 and (d) the phase of S11 using PCA.
