In vivo terahertz sensing of psoriasis and eczema patients

Abstract

Abstract In this study we present the first in vivo clinical study of patients with eczema and psoriasis using terahertz (THz) sensing. Eczema and psoriasis patients were measured using a handheld THz scanner, both before and after the application of moisturiser. We show that THz sensing can distinguish between dry and healthy skin in different regions of the body. Furthermore, the impact of applying moisturiser on the skin can also be observed and potentially evaluated using THz light.
