This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections. Society (IDS).

15.9 The color wheel approach This page has not yet been summarized.
16 Analytic approach The analytic approachThis glossary term has not yet been described. refers to algorithmic method for the diagnosis of pigmented lesions using dermoscopy.

The essence of pattern analysis is a structured description formulated using a clearly defined algorithmic method. The diagnostic method is structured in such a way that one starts by describing the most general of features, then proceeds progressively to finish with the most specific features. The algorithm always takes the general form: Pattern + Color + CluesEvidence, in an investigation = Diagnosisis the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different disciplines with variations in the use of logic, analytics, and experience to determine "cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions Using patterns, colors and cluesEvidence, in an investigation, the number of potential diagnoses is progressively minimized. Pattern is a method by which algorithms are constructed.

Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections..
