Clinical Optical Imaging
 |
We are developing optical, spectrally-agile devices with clinical applications (surgery). These exploit fluorescence imaging in the Near-Infrared (NIR) optical region (650-1000 nm). Tissues are ‘transparent’ in the NIR band and these devices will ultimately allow us to detect and image tumour tissues at depths up to 10-15 mm. |  |

A fast method for estimation of light flux in fluorescence image guided surgery We present a theoretical method to estimate the light flux in near-infrared fluorescence imaging of tissues. This method is a very good approximation to the more usual Monte-Carlo methods, but runs in a fraction of the time. A Windows executable called FIFAC.exe is available that implements this method in Software Downloads. |
