Abstract
The invention discloses a liquid metal in-vitro marker device for in-vivo structure tracing and a tracing method. A liquid metal layer prepared from liquid metal is adopted as a visual marker and a medical imaging marker at the same time, and the problem that in the prior art, the space positions in two kinds of imaging processes are not consistent, and additional marking is needed is solved. A flexible thin layer can be obtained to be directly attached to the surface of an imaging object as a recognizable marker, the stability of internal structure tracing is guaranteed, and interference of the marker with imaging is reduced. Meanwhile, multiple light and thin recognizable markers can be utilized for forming a traceable marker array, and an internal structure to be traced can be covered better. According to the liquid metal in-vitro marker device for in-vivo structure tracing and the tracing method, a larger number of recognizable markers large in covering area are manufactured through a printing or coating method, the cost can be reduced, and the precision of tracing of the in-vivo structure can be improved.
Description
technical field [0001] The invention relates to the technical field of computer-aided medical treatment, in particular to a liquid metal external marker device and a tracking method for internal structure tracking. Background technique [0002] In vivo structure tracking refers to the measurement and tracking of the spatial position and attitude of specific tissue structures inside the organism through a certain technical method (usually using medical imaging methods). In the field of medical technology, internal structure tracking is required in surgical guidance equipment such as electrode placement, puncture, nail placement, ablation, and radiotherapy. Such equipment is widely used in clinical departments such as neurosurgery, orthopedics, interventional, and radiotherapy. . [0003] In vivo structure tracking method based on body surface markers, first place body surface markers for tracking on the body surface near the structure to be tracked, and use medical imaging e...
