Hyperspectral imaging for skin cancer and blood disorders diagnosis

Abstract

Hyperspectral imaging is a novel technology for acquiring an image at a large number of wavelengths, thus allowing the study of spectral and spatial details of a sample under analysis. This technology has emerged as a promising imaging modality to be used as a diagnostic tool in several medical applications where spectral information is relevant. In this paper, we outline our most recent achievements in this field. Firstly, hyperspectral imaging systems developed to improve non-invasive diagnosis of skin cancer, consisting of digital silicon and InGaAs cameras and light emitting diodes, are described. Secondly, we present our last advances using hyperspectral technology together with confocal microscopy to improve the diagnosis of blood diseases, in particular, hemoglobinopathies such as thalassemia and cell membrane diseases such as hereditary spherocytosis. Finally, new insights on these topics are discussed.
