Hand-held Fluorescent Ultrasound Fusion Contrast Imaging Navigation System

Abstract

The invention discloses a handheld fluorescent ultrasonic fusion radiographic navigation system. A multi-spectrum source exciting module excites near-infrared laser and visible white light; a handhelddetector module includes a fluorescent probe and an ultrasonic probe integrated to each other; the fluorescent probe irradiates tissue of an open living body to obtain a fluorescent image of a specific tissue part; an information processing module processes the fluorescent image to obtain an enhanced fluorescent image including position and boundary of diseased tissue; a high-frequency ultrasonicexciting module excites multi-frequency ultrasound according to the displayed position and boundary of the diseased tissue, an ultrasonic probe performs ultrasonic detection on the diseased tissue toobtain a continuous two-dimensional ultrasonic image of the diseased tissue; the information processing module performs 3D registered fusion on the continuous two-dimensional ultrasonic image to obtain a 3D ultrasonic image of the diseased tissue; the information processing module transmits the 3D ultrasonic image to a display for displaying, and the enhanced fluorescent image and the 3D ultrasonic image provide real-time surgical video navigation for surgeons.

Description

technical field [0001] The invention relates to the technical field of multimodal medical imaging, in particular to a hand-held fluorescent ultrasound fusion imaging navigation system. Background technique [0002] The hand-held navigation system is used in general clinical operations. It refers to the handheld device used by doctors during the operation that does not invade the interior of the living body. The intraoperative navigation is completed by detecting the surface of the living body. With the development of medical imaging technology, molecular image navigation equipment has become an "observer" and "intelligence agent" to assist doctors in the operation process. Among them, the hand-held navigation system based on optical fluorescence imaging has been seen in clinical applications. The specific fluorescence imaging method is obtained by exciting tissue with laser, which can effectively judge the outline of tumor or diseased tissue. Although the optical fluorescen...

Problems solved by technology

Although ultrasound can effectively obtain deep images of tissues, it cannot provide fast navigation for doctors to find areas of interest (tumors, blood vessels, etc.)
