The Light-CT Scanner is a high-resolution imaging device for cellular-level biological tissue imaging. It performs non-invasive and non-destructive real-time optical biopsy.

In depth microscopic tissue visualization in a fast, non-destructive manner without the use of contrast agents could improve the clinical diagnostic process.
LLTech’s optical technology is based on Full Field Optical Coherence Tomography (FFOCT), a technique that enables volumetric image capture on tissue samples at micron resolution in 3D.
The technology intends to assist diagnosis, particularly of cancer, in skin, breast, prostate, brain etc, as well as quality control of biopsies.
The Light-CT system is a high-resolution (1µm 3D) pathology scanner that performs optical slicing beneath the tissue surface at selected depths. Within a few minutes, the tissue architecture and microstructure is revealed, in 2D and 3D, without damaging or modifying the sample under analysis.

In the context of tissue imaging for cancer diagnosis, LLTech anticipates the following benefits:

  • Better image quality: the full-field OCT technology employed by the Light-CT Scanner is the sole technique to offer axial resolution (i.e. in the vertical, z-axis) of 1 µm, which gives the best image clarity and precision.
  • Speed (rapidity of diagnosis): the technology currently enables image capture on a 1 cm2 region of tissue in 4 to 5 minutes, thereby enabling immediate quality control of biopsies.
  • Avoiding patient recall in the event of complex biopsies that require hospitalization and/or anesthesia.
  • Non-destructive technology that allows reuse of the biopsy: no need for dyes, contrast agents or tissue freezing
  • Analysis can be carried out remotely
  • Ease of use: LLTech products can be employed directly. No calibration or complex set-up procedure is necessary. User training is completed in under half a day.

The following video demonstrates the use of the Light-CT scanner.

 

Intended Use Statement: The Light-CT Scanner is intended to acquire, store, retrieve, display, and transfer optical coherence tomography images of unsectioned excised surgical tissue for review by physicians to assist in forming a clinical judgment. The Light-CT Scanner is not intended as a primary means of diagnosis. The Light-CT Scanner is certified for research use only.
