Abstract
We developed near-infrared fluorescence imaging system for indocyanine green (ICG) as optical enhancer and tried to use the system for evaluation purpose of blood and/or lymphatic vessel observation during the operation. The excitation wavelength of ICG is in the near-infrared wavelength between 750 and 810 nm, and the fluorescence occurs maximum wavelength at 845 nm in plasma.
The near-infrared fluorescence imaging system Photodynamic Eye (pde-neo, Hamamatsu Photonics, Hamamatsu, Japan) is equipped with light emitting diode (LED) that emits near-infrared wavelength of 760 nm as excite light and a charge-coupled device (CCD) as image detector with an optical high-pass filter in front of CCD so that fluorescence signal can be detected efficiently. This system consists of the camera unit, controller which operates the camera unit, and remote controller which controls the LED intensity, video gain, and offset. The fluorescence image is sent to a digital video processor to be displayed on a TV monitor in real time.
The features of the system are safe (X-ray radgiation-free), compact size, real time, user-friendly, and cost-effective. It’s verified that the system is applicable to various applications and promising technique for intraoperative diagnosis.
