Optical coherence tomography enables high-resolution, nondestructive imaging up to 1 mm in depth.

• Full 3D reconstructions allow for visualization of the full extent of tumor

• Estimation of tumor content allows for spatial exclusion in important personalized cancer treatment assays.
– Also useful for relevant 3D drug development assays

SPIE Paper No. 11220-7

Successful development of a singlet oxygen spectrometer applicable for PDT treatment using a cw laser

Preliminary demonstration during in vivo animal experiments

Continued animal study is ongoing.

Next step will be to reduce the system cost and potentially include time gated measurement capability.
