Clinical application of the proposed selective spectral imaging method. (A) RGB image of an H&E-stained tissue slide. The white dashed box indicates the wide-field imaging area; red and blue lines outline cancerous and normal tissue regions, respectively. (B) Ground-truth spectral profiles of cancerous and normal tissues. (C) Measured wide-field images at two DMD patterns targeting cancerous and normal tissue areas. Scale bar is 0.5 mm. (D) Spectral profiles of cancerous and normal tissues acquired using the proposed method.
