HT-HUD: Advanced Skin Analysis through Thermal Imaging

A revolutionary method for the early detection of skin cancer.

Sweden has one of the highest incidences of skin cancer in the world, with a continuously increasing trend. Only Australia and New Zealand have higher figures. Annually, approximately 60,000 cases are diagnosed in Sweden, with 500 fatalities. UV radiation from the sun is the primary risk factor, and despite increased awareness of sun protection, the number of cases continues to rise.

Technical Components

IR Camera

Detects infrared radiation from the skin, providing a detailed image of the skin's temperature distribution. Measures temperature differences with high precision to detect anomalies.

UV Camera

Displays the skin's reaction to ultraviolet light, revealing hidden changes not visible to the naked eye. Particularly effective in identifying early skin changes.

Visible Light Camera

Provides a standard visual image of the skin's surface, complementing the information from IR and UV cameras. Used for documentation and long-term follow-up.

Scientific Background

Research Basis

Based on established and recognized research:

  • Laser Doppler technology for blood flow analysis.
  • Studies on hypodermic responses and vascular changes.
  • Thermal imaging used for physiological evaluation.

Research References:

  • Roustii M et al. Trends Pharmacol Sci 2013; 34:373–84
  • Bergengren et al. Ophthalmic Plast Reconstr Surg. 2019

Scientific Principles

  • Angiogenesis affects the skin’s thermal distribution patterns.
  • Tissue density and vascularity vary in cancerous vs. healthy areas.
  • Thermal signatures change according to metabolic activity.

These parameters provide a measurable scientific foundation for differentiating normal and abnormal tissue behavior.

IR and UV Imaging Overview

  • Infrared (IR) and Ultraviolet (UV) techniques visualize both surface and subsurface responses.
  • IR detects heat flow and vascular function.
  • UV reveals hidden structural and pigmentation damage.

Together they create a multi-layered diagnostic perspective.

Infrared (IR) Imaging

  • Clinically used to monitor temperature variations in the skin.
  • IR is divided into three bands: IRA (near-IR), IRB (mid-IR), IRC (far-IR).
  • Each wavelength penetrates to different depths within the dermis.
  • Thermal cameras ensure safe, controlled heating at 32–35 °C.

These measurements reflect vascular activity and tissue response to thermal stimulation.

Ultraviolet (UV) Imaging

  • Highlights subsurface skin changes invisible to the naked eye.
  • Reveals collagen damage and UV-induced alterations in elasticity.
  • Maps hydration, pigmentation, and early photoaging patterns.
  • Used for before/after comparisons to show progressive damage.

UV imaging therefore plays a critical role in preventive dermatology and skin-health monitoring.

Summary

  • IR and UV imaging jointly provide objective physiological data.
  • Enable non-invasive, repeatable analysis of thermal and optical skin behavior.
  • Used in clinical, cosmetic, and research environments worldwide.

This combined methodology forms the technological foundation of HT-HUD diagnostics.
