A new approach to medical imaging using an instrument that can reveal details of tumours and tissues with a precision 1,000 times sharper than existing techniques has been developed by American scientists.
Raman spectroscopy can picture internal anatomical features within an accuracy of nearly a billionth of a millimetre and has already been used to image both normal tissues and tumours in mice. It could be particularly useful in cancer surgery, allowing doctors to detect and remove tumour particles that are too small to be picked up and excised using existing techniques.
