SELECTIVE EXCITATION LIGHT FLUORESCENCE IMAGING METHODS AND APPARATUS

摘要

Imaging methods and apparatus may be applied to image tissues as well as other areas. A computer-controlled color-selectable light source is controlled to emit light having a desired spectral profile and to illuminate an area. An imaging detector images the illuminated area. The spectral profile may be selected to yield images in which contrast between features of interest and other features is enhanced. The images may be combined into a composite image. In some embodiments the spectral profile is based on a principal components analysis such that the images each correspond to one principal component.
