Illustration of the hyperspectral imaging setup. By capturing images of the lumpectomy specimen (A), a three-dimensional array of images can be generated across a broad range of the electromagnetic spectrum (B). Five example images out of the total 528, each captured at a distinct wavelength, provide diverse spatial information about the specimen (C). Every pixel in the image also contains spectral information, offering additional details about the tissue’s composition. By considering this information for multiple wavelengths, a diffuse reflectance spectrum, i.e. an optical fingerprint can be generated for each pixel which enables the detection of cancer cells.
