    LLTech brings optical biopsies to operating theaters: Coherence tomography technique allows surgeons to see biopsy results in 3D and almost real-time.
    Optical biopsy techniques have been a focus of interest in biophotonics for many years. The use of spectroscopy to provide the kind of diagnosis that must normally wait for histology or cytology is an attractive proposition, potentially saving time, money and patient discomfort. Now LLTech, a venture-stage company based in Paris, has developed a coherence tomography process called Light-CT that could present surgical staff with 3D visualizations of tissue samples in something very close to real-time. "Light-CT technology leapfrogs all other coherence tomography approaches and product platforms in terms of laboratory, clinical and operational requirements," claims Bertrand Le Conte de ...

  2. Quotes

    1. "The CT principle involves using light with a relatively broad spectrum, and the broader the spectrum is, the better the sectioning ability of the technique...That illumination commonly comes from a superluminescent diode or an ultrashort pulsed laser, but Light-CT is completely different.
    2. Light-CT technology leapfrogs all other coherence tomography approaches and product platforms in terms of laboratory, clinical and operational requirements,..."There is at present no device enabling real-time 3D imaging of biopsies, since current imaging techniques in pathology are destructive, two-dimensional and non-digital.
    3. Today, up to 40% of women having breast cancer surgery must go through a second procedure to complete the surgery, to remove either the remaining parts of the tumor or the nodes chain...The morphological information from a Light-CT scanner could allow a distinction between normal or cancerous tissue structures to be made within minutes, during the initial surgical procedure. Then an evaluation of whether the procedure should continue or be stopped can be made.
