Abstract

MéTODOS PARA A DETECçãO DE TECIDO EPITELIAL ANORMAL A visibilidade de tecido anormal sob luz que tem picos de comprimento de onda que identificam seletivamente tecido anormal é melhorada na presença de luz ambiente normal por visualização do tecido através de lentes que transmitem os picos de comprimento de onda mas bloqueiam a transmissão de outros comprimentos de onda.
