  • Patent number: 11243166
    Abstract: An intraoperative near-infrared-I and near-infrared-II multi-spectral fluorescent navigation system and method of using same includes a light source module for emitting white light and excitation light for illuminating tissue to be tested to generate an emission light. An optical information collection module includes a white light camera for collecting the white light image, and near infrared-I and near infrared-II fluorescence cameras for collecting the near infrared-I and near infrared-II fluorescence images. A central control module is coupled to the light source and the optical information collection modules. An image processing unit pre-processes the white light image, and the near infrared-I and near infrared-II fluorescence images, for de-noising and enhancement.

  • Publication number: 20210000437
    Abstract: A second near-infrared window/first near-infrared window dual-mode fluorescence tomography system having a lighting module, an excitation module, a second near-infrared window collection module, a first near-infrared window collection module, a CT imaging module and a central control module. The central control module is configured to reconstruct second near-infrared window three-dimensional and tomographic images and first near-infrared window three-dimensional and tomographic images based on the white light images, the second near-infrared window fluorescent images, the first near-infrared window fluorescent images, and the CT images. The reconstructed three-dimensional space tumor signal has depth characteristics, which is closer to the real distribution of tumors, such that the reconstruction position is more accurate. The three-dimensional shape of the tumor is displayed intuitively and clearly at any angle with the usage of image display unit.
