Medical image space localization device and method

Abstract

According to the embodiment, the invention provides a medical image space localization device and a medical image space localization method. The device comprises an optical localization unit, first mark points and second mark points, wherein the first mark points are arranged on a target operation position of a patient; the second mark points are arranged on the target position of the patient in accordance with the first mark point units; a coordinate relation between the first mark points and the second mark points in a world coordinate system is described by virtue of a transformation matrix; the optical localization unit is used for identifying the first mark points, so that coordinates of the first mark points in the world coordinate system are obtained; in accordance with the coordinates of the first mark points in the world coordinate system as well as the transformation matrix, coordinates of the second in vitro mark points in the world coordinate system are obtained; and in accordance with the coordinates of the second mark points in an image space, automatic localization of a medical image space is achieved in a natural visible light environment; therefore, by virtue of the localization device and the localization method, the automatic localization of the medical image space is achieved in the natural visible light environment.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical robots, and in particular, to a positioning device and method in a medical image space. Background technique [0002] Automation equipment such as robots has been widely used in the industrial field, showing obvious advantages in terms of operational flexibility, stability and accuracy. In order to solve the problems of insufficient precision, excessive radiation, large incisions, and operational fatigue in surgical operations, people have begun to discuss how to introduce robotic methods in surgical operations. The treatment method and system of the invention can solve the above problems and improve the surgical effect, that is, using medical robots to achieve surgical operations, including nerves, head and so on. [0003] In order to realize the operation, the localization in the medical image space must be solved. In the prior art, the spatial positioning methods of medi...

Problems solved by technology

[0004] For manual positioning, the operator's arm usually shakes, deviates, etc., which easily leads to insufficient positioning accuracy; for automatic positioning, because it must be based on specific technologies such as special light sources and sound sources, etc., the implementation cost is relatively high. high
