Targeted puncture guiding system and method based on multi-modal medical image information

Abstract

The invention discloses a targeted puncture guiding method based on multi-modal medical image information and further discloses a targeted puncture guiding system based on the multi-modal medical image information. The targeted puncture guiding method comprises the steps that a structure image capable of recognizing a target organ anatomical structure is utilized as first information; a functionalimage capable of displaying functional metabolism information of a target organ is utilized as second information, and according to the functional image, the position of a to-be-punctured target is recognized; a guiding image capable of real-timely displaying the target organ and then guiding a puncture instrument to reach to the position of the to-be-punctured target is utilized as third information; spatial positioning information, real-timely obtained by a spatial positioning system, of the guiding image is utilized as fourth information; and the puncture path of the puncture instrument isplaned through fusion of the first information, the second information, the third information and the fourth information, and the puncture instrument is real-timely guided to advance along the puncture path. Targeted puncture accurate guiding based on multi-modal medical image information fusion can be achieved, a three-dimensional view is sufficiently utilized, and the puncture accuracy and operating convenience are improved remarkably.

Description

technical field [0001] The invention relates to the field of medical instruments. More specifically, the present invention relates to a targeted puncture guidance system and method based on multimodal medical image information. Background technique [0002] Malignant tumors are a class of diseases that seriously endanger human health. With the advancement of medical technology and the improvement of people's health awareness, the early detection and early treatment of malignant tumors have been widely recognized by doctors and patients and have preliminary clinical applications. Interventional medicine is a type of technology developed under this background. It is an extension of medical imaging and can be diagnosed and treated under the guidance of medical images. It has the characteristics of small trauma, strong pertinence, fast and efficient. [0003] However, at present, most interventional diagnosis and treatment are guided by traditional imaging techniques (such as ...

AI Technical Summary

Problems solved by technology

[0003] However, at present, most interventional diagnosis and treatment are guided by traditional imaging techniques (such as traditional CT and ultrasound imaging). Due to the inherent defects of these traditional imaging techniques, the imaging of target lesions is blurred or even invisible, and doctors cannot accurately locate lesions and provide precise intervention Difficulties in diagnosis and treatment

On the other hand, the emergence of various advanced imaging techniques in recent years has enabled doctors to more precisely locate, diagnose, track and evaluate tumors, but these imaging techniques are often not suitable as a means of guidance
