Detection device and method of endoscopic-type early pancreatic carcinoma imaging

Abstract

The invention relates to a detection device and method of endoscopic-type early pancreatic carcinoma imaging. The device comprises an ultrasonic endoscopic probe, a microwave generator, a microwave radiation unit, a data acquisition card, a computer, a magnetic stirrer, a centrifugal machine and a freeze dryer; the magnetic stirrer, the centrifugal machine and the freeze dryer are used for preparing targeted nanoparticles injected into a human body through veins; the microwave generator emits pulse microwave signals to the human body into which the targeted nanoparticles are injected through the veins through the microwave radiation unit, and utilizes a thermoacoustic effect to stimulate and generate ultrasonic signals; the ultrasonic endoscopic probe is used for receiving the ultrasonic signals and converting the ultrasonic signals into electrical signals, the electrical signals are imported into the computer through the data acquisition card to be subjected to image reconstruction processing, and microwave thermoacoustic imaging is obtained. According to the detection device and method of endoscopic-type early pancreatic carcinoma imaging, the targeted nanoparticles, combined with a microwave thermoacoustic imaging system, are used for early pancreatic carcinoma detection, and not only are toxic and side effects small, but also the accuracy of the early pancreatic carcinoma detection is improved.

Description

Technical field [0001] The invention belongs to the technical field of microwave thermoacoustic imaging, and specifically relates to a detection device and method for endoscopic early pancreatic cancer imaging. Background technique [0002] Pancreatic cancer is one of the cancers with extremely high malignancy and fatality rate, and its incidence rate is increasing year by year. Early detection of pancreatic cancer is the only effective way to improve the survival rate of patients. Existing medical imaging methods such as B-ultrasound, CT and MRT are difficult to detect early pancreatic cancer below 1cm. Microwave thermoacoustic imaging, as a new non-destructive testing technology, not only has the advantage of high resolution of ultrasonic imaging images, but also has the advantages of It facilitates detailed observation and analysis of tissue structure and provides the possibility for early detection of pancreatic cancer. Existing thermoacoustic imaging systems cannot det...
