Photoacoustic dermatological imaging device
The Dermagio imaging device supports dermatological diagnosis, treatment monitoring, and research. Utilizing advanced photoacoustic technology, Dermagio visualizes microvessels beneath the skin and segments them into anatomical layers—offering structural and functional insights that go beyond traditional imaging methods.
Dermagio consists of three core components: a laser subsystem that delivers imaging light, a handheld photoacoustic probe for direct skin contact, and a control unit for system operation and data processing.
In evaluating skin conditions, Dermagio’s dedicated software enables intuitive visualization and quantitative analysis. Volumetric image data provides depth-resolved information, and skin layers can be segmented based on anatomical structures for independent evaluation. This segmentation also enables advanced applications, such as assessing vasoconstrictive responses or monitoring therapeutic efficacy.
Anatomical layer imaging
Immune and inflammatory skin diseases
Skin cancer (both melanoma and non melanoma)
Vascular conditions and structural imaging
Diagnosis and treatment monitoring of melasma in the epidermis and dermis
Clinical assessment of dermatological agents.
Microneedle research
Skin ageing and skin quality
Tumor progression and regression monitoring
Layer by layer visualization of subdermal microvessels and pigments
Endogenous hemoglobin and melanin allow for daily monitoring
Optics, acoustics, and electronics are configured in one movable unit
A single button on the probe initiates two imaging modes (pre- and standard diagnosis)
