DETERMINING THE EXTENT OF A STRUCTURE ON OR IN THE SKIN OF A SUBJECT

摘要

A method of and determining the extent of a structure (1), such as a non- melanoma skin cancer, in or on the skin of a subject, the method comprising the steps of: placing an index marker (3) on the skin adjacent to the structure (1); positioning an optical coherence tomography device (8) relative to the index marker; using the optical coherence tomography device (8) to image the structure (1) so as to create an image of a cross- section through the skin determining the position of an edge of the structure (1) in the image; and translating that position of the edge in the image to a position on the skin relative to the index marker (3). An associated kit of parts for use in determining the extent of the structure (1) is also disclosed.
