millimeter-wave imaging

This work presents an innovative, low-cost, easy-to-fabricate, and simple-to-use probe that can detect early-stage skin cancer. As can be seen above, the probe scans the suspected skin area to enable capturing the reflection coefficient at each position. The collected data is then processed to infer the presence of skin cancer through a differential approach. In order to do this, a novel imaging function is utilized to enable the detection of relative permittivity changes with respect to the healthy region surrounding the suspected one, resulting in the 2D image depicted above. read more
