Study On Magnetic Resonance Images Of Carp Robot's Motor Control Sector

Carp robot is a typical aquatic animal robot,and the accuracy of electronic physiological stimulation site is a key factor in deciding whether or not to successfully control its behavior.Therefore,brain stereotaxic technique is an indispensable technical means in the field of brain control mechanism.Traditional carp brain stereotypes neither visually visible to tissues or nuclei,nor strictly limit the size and placement of carp posture.The location efficiency is low and the accuracy is poor.This paper intends to use the magnetic resonance imaging instrument to visualize the spatial structure of carp and brain.In the visualization of carp brain image,when measuring the value of T1 and T2 of the brain tissue,cerebrospinal fluid,fat and comparing them longitudinally,we found that the T1 value of brain tissue was the longest and the T2 value was the shortest,so the T2 WI sequence imaging was selected.It is found that TR is 2500 ms,the image quality is the best.Compared with different diameter tungsten wire,copper wire and nickel chromium electrode image quality,it is found that the tungsten wire electrode with diameter of0.25 mm can accurately display the stimulus without affecting the image quality.The area and volume of each brain tissue were measured by image.The data showed that the area and volume of carp in the brain were larger than those in other brain tissues.The three-dimensional coordinate system of carp was established,and the positioning markers were designed in the skull of carp.The magnetic scanning layer was combined with the plane of the auxiliary coordinate system to realize the accurate positioning of any point in the brain.By applying the method,The positioning of the carp nucleus and the electrical stimulation test were carried out,and the coordinate values of the left,upper,right and lower sides of the tissues were measured,which provided an important position for the study of the craniocerea robot.In this paper,the interpolated method of linear interpolation is the best.The method of regional growth is used to segment the brain tissue,and the method of image interpolation is used to segment the brain tissue.Skull and brain tissue separation,to facilitate the studyof brain tissue alone.At the end of this paper,MC algorithm and Ray-Casting algorithm were used to reconstruct the surface of the carp and reconstructed.The structural features and internal distribution of the carp were obtained.The VTK design pattern and the basic control were used to realize the reconstructed 3D solid Arbitrary section cut,any face cutting,threedimensional entities on the straight line,surface distance measurement.Through the threedimensional entity World coordinates to the spatial positioning coordinates can achieve the mouse dynamic selection of positioning coordinates and enrich the positioning of carp robot positioning means.
