Abstract
A multimodal apparatus for analysis of allergic reactions during skin tests and a method of multispectral imaging of allergic reactions in case of the type I and the type IV allergic reactions induced by performing skin allergy Prick and Patch tests combine thermal imaging with Laser Doppler flowmetry or 3D scanning to confirm the results of epidermal hyperthermia tests.
Claims4
A method for imaging allergic skin reactions during a Prick test or Patch test applied to a tested area of a patient's skin, comprising:
- in the case that a Prick test is applied, recording a hyperthermic component of an allergic Type I reaction occurring at the tested area using a thermal imaging camera and also performing transdermal laser Doppler flowmetry at the tested area;
- in the case that a Patch test is applied, recording a hyperthermic component of an allergic Type IV reaction occurring at the tested area by using a thermal imaging camera and also recording an optical component reflecting a topography of the tested area with identification of surface skin lesions via optical reflectometry using a 3D scanner, and
- based on thermal imaging obtained either by the transdermal laser Doppler flowmetry or the optical reflectometry, developing an indication of the allergic reaction of the tested area.
