Fluorescence-Guided Surgery and Fluorescence Laparoscopy for Gastrointestinal Cancers in Clinically-Relevant Mouse Models

Figure 3

Stryker laparoscopic setup. A standard laparoscopic tower was slightly modified to achieve a fluorescence light mode that permitted detection of fluorescence signals while still allowing visualization of the background. The LED light source (Stryker L9000 LED lamp) was filtered through a glass emission filter (Schott GG495) that was placed between the laparoscope and the 1288 HD camera. With alterations to red, blue, and green components of the light source, we were able to visualize tumors of different fluorescent wavelengths. A Stryker X8000 Xenon light source was used for bright field laparoscopy [3].
