What’s the difference between contact and non-contact SIAscopy?
As the names suggest, contact SIAscopy involves touching the skin, and non-contact does not. Contact SIAscopy uses a proprietary hand-held scanner, which is placed on the area of skin being examined. The scanner measures an area of approximately 11mm by 11mm. Contact SIAscopy can measure haemoglobin, melanin, dermal melanin and collagen up to 2mm beneath the surface of the skin. This system is appropriate where, for instance, a pigmented skin lesion is under investigation. It gives the examiner detailed information about the distribution of the four major skin components to aid diagnosis. Non-contact SIAscopy uses an Astron Clinica-specified digital camera, does not touch the skin and can be used to image and monitor large areas of skin, such as the face or back. Non-contact SIAscopy can be used to examine haemoglobin and melanin. Not only does this system allow large areas of the skin to be imaged and monitored over time, but it is also important in instances where contact with the sk
