Design Of Near Infrared Based Tumor Detection And Imaging System

As a malignant disease,cancer is a serious threat to people's health and life.Studies have shown that the treatment of a newly discovered tumor cases,if the patient's lesion is not more than 1cm in time for treatment,it will have 90% chance to cure or long-term survival.Therefore,if you can detect the early stages of the tumor,and the timely treatment of patients,the survival rate of cancer patients will be significantly improved.And near-infrared spectroscopy technology compared to the current medical in the traditional tumor detection imaging methods,such as X-ray imaging technology,nuclear magnetic resonance imaging technology,ultrasound imaging technology,with the instrument easy to operate,production and application of low cost,the measurement process on the human body Which is not important to the adverse effects,it is devoted to research and development of a humanoid tumor detection system based on near-infrared array probe as a family universal device for the preliminary screening and investigation of malignant tumors,which is very achievable and Scientific significance and social significance.The research content of this paper can be divided into the following parts: simple analysis of near infrared light measurement of tumor application principle and background,and that Lambert's law and the revised lambert beer's law how to detect and calculate the body's blood oxygen concentration,then gives a detailed derivation process,and its application in the next measurement process.Researching and designing the STM32 as the core control part of the design of a new array of probe hardware imaging system,can achieve near-infrared light generation,control,and optical signal acquisition,processing and storage.Designing a hardware acquisition system to support the lower computer software and is responsible for the signal processing and imaging of the host computer software,in the process,in order to improve the image resolution,the translation experiment is added after the mobile extension interval is analyzed.On this basis,the method of support vector machine and two-dimensional image interpolation is proposed to further improve the imaging resolution and measurement accuracy.Near infrared light provides the possibility for new methods of noninvasive detection,diagnosis and clinical management of breast cancer.But in the final application of the human body in the process there will be more unpredictable factors of interference,so in this study of the experiment,the experiment made in the laboratory of micro-organization for the experimental and measurement of the object.Based on the existing modified Lambert-Beer's law,in order to overcome the disadvantage of low spatial resolution of near-infrared light imaging in this study,we study the fault in CT tomography In the near infrared ray imaging system of this study,a set of micrographs imaging system of light source-detector which can be used to stratify the measured area can be designed to imitate the target "tumor" and preliminary positioning,for the final human tissue tumor imaging and positioning to lay the foundation.In this system,we can clearly distinguish the level of "target tumor" in the final imaging of the host computer after the acquisition of the imitation model of "no target tumor" and the imitation model of "target tumor",and give the diameter of the measurement target.After several experiments of translation experiments,the resolution of the image has been improved obviously.The experimental data and the results show that the design system and the corresponding algorithm are correct.
