Cancer affects about one-third of the world’s population.
Cancer affects about one-third of the world’s population.
In order to expand surgical capabilities and improve patient prognosis, researchers such as Blair have developed a six-channel color/near-infrared image sensor inspired by the mantis shrimp vision system, which can guide near-infrared fluorescence images during surgery.

The imaging capability of the image sensor
The imaging capability of the image sensorIn order to provide information about the location of the tumor that cannot be provided by a single instrument, the researchers adjusted three color channels to visually observe the operation process, and adjusted three near-infrared channels to multiply the optical probe that highlights the cancer tissue.
Tumor detection rate by different methods
Tumor detection rate by different methodsIn athymic mice transplanted with human prostate tumors, the image sensor can simultaneously detect two tumor-targeting fluorophores, thereby distinguishing tumor lesions from healthy tissues in approximately 92% of cases .
