Unhealthy nutrition trends determination technique is described. Combination of optical spectroscopy and electrical
impedancemetry will lead to development of a healthcare device that will predict unhealthy eating habits and decrease
risk factors of diseases development.
In present paper, an ability to differentiate basal cell carcinoma (BCC) and healthy skin by combining multi-spectral autofluorescence imaging, principle component analysis (PCA), and linear discriminant analysis (LDA) has been demonstrated. For this purpose, the experimental setup, which includes excitation and detection branches, has been assembled. The excitation branch utilizes a mercury arc lamp equipped with a 365-nm narrow-linewidth excitation filter, a beam homogenizer, and a mechanical chopper. The detection branch employs a set of bandpass filters with the central wavelength of spectral transparency of λ = 400, 450, 500, and 550 nm, and a digital camera. The setup has been used to study three samples of freshly excised BCC. PCA and LDA have been implemented to analyze the data of multi-spectral fluorescence imaging. Observed results of this pilot study highlight the advantages of proposed imaging technique for skin cancer diagnosis.
Spectral imaging techniques are widely used in medical and biological research for example in skin cancer diagnostics. In this paper methods and equipment for spectral imaging of micro objects such as cells, their structure and histological samples are discussed.
