摘要
The device has an optical fibre bundle for illuminating the examined area, the light output controlled via an intermittent switch, to provide light pulses with a time duration of between 5 and 20 ns and a pulse spacing which is equal to or greater than, the decay time of the fluorescence of the marking material for the cancer tissue. The optical fibre bundle is directly coupled to an intermittently controlled image amplifier, associated with a video camera and at least 2 video memories, with synchronised operation of the image amplifier and the illumination light source. The images obtained by integration of the fluorescence images are subtracted or divided, to provide the monitor image. USE - For detecting cancer of soft organs.
