Psoriasis sensor gets under peoples’ skin

A new scanner can view under the skin surface for those with psoriasis.

When doctors assess the inflammatory skin disease psoriasis, they generally do so via a visual examination of the red, scaly patches on the skin’s surface. This can be subjective, however, plus it doesn’t take into account what’s going on at a deeper level. That’s why German scientists from Helmholtz Zentrum München and the Technical University of Munich have developed a handheld scanner that looks beneath the skin – and it doesn’t expose the patient to any harmful radiation.

Known as RSOM (raster-scan optoacoustic mesoscopy), the technology incorporates weak laser pulses that are used to slightly heat the tissue being examined. This causes the tissue to momentarily expand, which in turn generates ultrasound waves. The sensor is able to detect those waves, and analyzes them to create a high-resolution image of what’s happening under the skin.
