Mole non-contact siascopy, scanning


What types of SIAscopy are used in GK Clinic?

SIAscopy may be contact and contactless. Both of these SIAscopy types are implemented at the GK clinic.
GK Clinic was the first clinic in Lithuania and the Baltic countries, which has implemented the use of contact and non-contact, skin mole, pigmental formation and tumor SIAscopy diagnostics.


SIAscope – is a noninvasive spectrophotometric analyzer, which can help assess the condition of the skin to a depth of 2 mm. Because of the multi-layered skin structure, skin chromophore (hemoglobin, melanin, collagen), change the properties of the light spectrum. The device emits light ,after that, part of it is scattered, part of it is reflected from the surface of the skin, and the third part is absorbed by the cells and other formations of the skin. By understanding these interactions and by comparing the light which falls on the skin, with the total amount of light emitted, SIAscopy can identify the nature and location of many different cells and structures in the skin. SIAscopy measures the quantity of hemoglobin, melanin, collagen, dermal and epidermis melanin. Information about the scanned areas are called so SIAscopic images (SIAscans).They  show how monitored parameters vary on the surface of the skin. The information is then processed digitally stored and archived.

What does “Non-contact SIAscopy” stand for?

During the process of non-contact SIAscopy digital camera is used to capture images of cross-polarized examined area. The light source used is a small flashing light, which illuminates the entire visible area. The camera takes three pictures. A red, green and blue image, each of which covers a different area of the visible spectrum. These images are then analyzed in a similar manner to contact SIAscopy, thus creating non-contact  SIAscopy scans, which reflect the concentration of hemoglobin and melanin in the skin.

Why choose SIAscopy?

The light used in SIAscopy is completely safe, what makes this technology ideal for monitoring skin conditions. In addition, this method:

  • is specific and most accurate (its efficiency is about 90%);
  • provides the opportunity to monitor changes in the pigmental structures within a specified time period of time (eg.: after a year);
  • is fast;
  • does not require special preparation;
  • is painless, and performed without additional surgery.

What are the advantages of non-contact SIAscopy?

Contactless SIAscopy siascans are formed using a digital camera from a distance, which allows to take images of such a large area as the entire back or face. Currently, contactless siascopy can create blood and melanin images.
Contactless SIAscopy is particularly useful for monitoring the number of moles of one person and looking for changing moles, which may require a more thorough investigation.
