an information collection device

Abstract

The invention relates to the technical field of information collection, in particular to an information collection device. In the information collection device provided by the present invention, the laser light emitted by the laser source is transmitted to the self-focusing coupling fiber through the first discrete fiber, and the self-focusing laser beam output by the self-focusing coupling fiber is focused on the surface of the sample to be tested through a transparent ultrasonic probe to generate light. Acoustic signal, the transparent ultrasonic probe receives the photoacoustic signal; the rare earth-containing piezoelectric element is excited by the laser to generate fluorescence, and the fluorescence irradiates the sample to be tested to generate an optical signal. The optical signal passes through the transparent ultrasonic probe through the self-focusing coupling optical fiber and the second discrete end optical fiber Transmitted to the miniature CCD image sensor; the transparent probe can also emit and receive ultrasonic signals by itself. The device can collect the optical signal, photoacoustic signal and ultrasonic signal of the sample to be tested. After analyzing and processing the three signals, the internal situation of the sample to be tested can be observed. The imaging results of the three signals are compared with each other, and the advantages and disadvantages are complementary. Greatly improve the accuracy of detection.

Traditional blood vessel detection methods include magnetic resonance angiography, CT angiography, etc. Although these methods can display the external shape and internal contour of the blood vessel well, they cannot show the detailed structure of the vessel wall and the vessel lumen. Intravascular ultrasound imaging Using a micro-ultrasound transducer to detect the size of the lumen and the structure of the vessel wall through internal imaging of the vessel, it can display the anatomical structure of the cross-section of the vessel in real time, and plays an irreplaceable role in the detection of various vascular diseases

[0003] As far as the current technology is concerned, the images obtained by simply collecting ultrasound signals and using ultrasound imaging may have artifacts, which cannot completely and accurately reflect the structure of blood vessels.
