Offhand I think you have a pretty good chance. Your main problem will be getting enough light into and out of the deep levels, where the implants are. You may want to consider some sort of transmission measurement rather than reflection, to reduce the amount of light that comes back without penetrating deep enough to tell the difference. \o/ /_\ |

great thank you, all of the provided information helps me a lot............ Basically the question is if it is possible to distinguish between "real" breast and "fake" (implanted) breast by non-invasive NIR spectroscopy... thanks again to all so far ! nick |

Of course, NIR Publications' latest book may have some useful information: http://www.impublications.com/shop/Identification-Human-Breast-Cancer-NIR-spectroscopy.html. I have alerted the author, Shou-He Yan, to the discussion and she may be able to offer some advice. |

Emil Ciurczak said he and others covered tumors and breast exams in the book (Medical & Pharmaceutical uses of NIR). Emil's email address is [email protected] and web site is www.thenirprof.com Bruce |

My understanding is that there are basically two types of breat implants. One type are the silicone-based ones, as has been described, but there are also implants that are filled with saline. Those may not be so easily detectable. \o/ /_\ |

Nick, if the implant is made of a NIR-absorbing material (almost everything except glass, quartz, etc) it can be detected. But keep in mind that the material must have a chemical composition distinct of the human tissue - probably it's always the case. As example: if you want to detect a silicone-based breast implant, surely the chemical composition differs from breast tissue; a first attempt could be made with short-wave NIR (800-1100 nm), where human tissue has a minimum absorption. But keep in mind that powerful light sources must be used. Use a backscattering reflectance probe placed on skin, probably will work. Hugs, Gustavo. |

Hi Nick, Yes, there is commercial product out there in the market that uses NIR for cosmetic purpose. But I don't recall the name of company. Maybe I can dig in if you are interested. There are also some studies that use NIR to detect breast cancer. Jerry Jin |

Hi there, a quick question, does anyone think it would be possible to do NIR measurements on breast tisssue to detect e.g. an underlying implant? is there any chance to penetrate that deep? thx ! nick |
