Interventional Imaging System

Abstract

An embodiment of the present invention provides an interventional imaging system, including a light source unit, a beam shaping unit, a visible light-terahertz imaging fiber bundle, and an imaging unit. The annular terahertz wave is transmitted through the annular terahertz imaging fiber bundle in the visible light-terahertz imaging fiber bundle, the visible light is transmitted through the visible light imaging fiber bundle, and finally the visible light reflected by the imaging target and the annular terahertz wave are respectively transmitted through the imaging unit. Terahertz waves are received and imaged based on the received visible light and ring-shaped terahertz waves. It can safely and harmlessly realize the joint synchronous imaging of interventional visible light and terahertz waves, and obtain the results of visible light imaging and terahertz imaging simultaneously. By comparing terahertz images with visible light images, the contrast, readability and accuracy of in vivo interventional imaging results are further improved.

Description

technical field [0001] The present invention relates to the technical field of optical imaging, more specifically, to an interventional imaging system. Background technique [0002] In the medical field, medical personnel usually need to identify diseased areas in patients through medical imaging technology. [0003] Currently, conventional medical imaging technologies include X-ray imaging, computed tomography (Computed Tomography, CT) imaging, magnetic resonance imaging (Magnetic Resonance Imaging, MRI), ultrasound (Ultrasound, US) imaging, and fiber optic endoscopic imaging. Among them, the design and process of the endoscope are limited, resulting in the imaging effect being easily affected by noise. MRI and CT imaging are easily affected by tissue parameters, resulting in imaging results containing multiple layers of tissue, the signals are relatively complex, some of them are difficult to characterize, and they are easy to miss diagnosis, which has certain limitations...

Problems solved by technology

[0004] Although terahertz imaging has advantages in the identification of lesion areas, due to the long wavelength of terahertz, it is easy to diverge, and the imaging resolution is not high, so it is necessary to use optical fiber bundles for interventional imaging

However, due to the high water content of the organism as a whole, the terahertz will be strongly absorbed by water, the signal returned to the camera or detector is weak, and the imaging contrast is not high, which makes it impossible for medical personnel to perform follow-up analysis of lesions and follow-up lesions based on the resulting images.
