Abstract: THz spectroscopic imaging is highly sensitive to water content, and as abnormal water content is usually indicative of afflictions THz imaging has great medical potential in early-stage disease diagnosis. However, clinical use requires fast acquisition, repeatability and cost-effective, reliable equipment, which is not yet offered by THz technology. In this work we have reviewed the methods and technologies that have the potential of allowing the transference of THz from the laboratory to the hospital. First, we discuss the need for reliable sample characterization and the calibration methods that overcome the relevant problems. Second, we discuss the usefulness of THz in disease diagnosis and further outline how occlusion of the skin must be accounted for accurate diagnosis. Thirdly, we discuss how adaptive sampling and smart image under-sampling can be used to reduce measurement times.
