| Abstract: | As for the deep weak optical signal detection in tumors, the endoscopic fl uorescence data acquisition system based on minimally invasive optical fi ber probe was designed. The system is used to assess the treatment of photodynamic therapy of tumors. The system is divided into two parts, photovoltaic detection and data acquisition. The photovoltaic detection part is based on CR186 photomultiplier tube. The data acquisition part is based on PCI-6251 data acquisition card. It uses Labview as the software platform for real-time display and data storage. The system is able to refl ecting the deep light intensity changes in tumor instantly. Our research has a signifi cant value in the development of medical equipment in vivo. |
