Skin Vasculature & Blood Flow

VivoSight Dx produces and characterizes vascular network images

Understanding cutaneous vascular presentations is a prerequisite for effective research programs including:

  • Clinical research involving systemic and topical medications
  • Optimization of treatment parameters for lasers, energy devices etc

Quantify treatment effects by measuring vessel density before and after treatment

Besides imaging vascular networks, VivoSight Dx and VivoTools measure the following vascular properties:

  • Vessel density by depth
  • Depth of the superficial vascular plexus
  • Modal vessel diameter of the superficial plexus
  • Density of vessels at the plexus level

VivoSight Dx Measurements Can Enhance Research of Inflammatory and Vascular Conditions:


In addition to marked morphologic differences (thickened and bright stratum corneum, acanthosis), the number of blood vessels and vascular density is increased in psoriasis. Images courtesy of Welzel [3].

Images shows a reduced number of vessels after application [Right]
Images shows a reduced number of vessels after application, however many of the medium to large vessels are still visible (right). Yellow bars indicate the location where measurements of vessel diameter were performed. The measurements showed a reduced vessel diameter of 42% after the application of brimonidine (diameter at baseline: 0.08 mm; diameter after brimonidine application: 0.046 mm).

Plot of Vessel Diameter Distributions in Port Wine Birthmarks - Dr Jill Waibel, Miami Dermatology Laser Institute
Histograms of vessel diameters at three selected depths in a hemangioma. From this data it is possible to estimate both the cross-sectional area and the volume of vessels of a particular diameter range and depth range that is to be treated by laser.
