Disclosed are an automatic planning method and a device for tissue ablation. The method includes: obtaining a three dimensional (3D) model of a to-be-ablated tissue through a 3D reconstruction technique; marking a cylindrical ablation point on the 3D model through an ablation planning, an axial direction of the ablation point is the same as a radio frequency direction of thermal ablation; and displaying an ablated area on the 3D model, the reconstruction technique includes: obtaining slice images of the to-be-ablated tissue in a plurality of directions, the slice image in each direction includes a plurality of two dimensional (2D) images; depicting, by a primitive, the to-be-ablated tissue on the 2D images in one direction; and constructing the 3D model of the to-be-ablated tissue through the 3D reconstruction technique based on the original 2D images.

Disclosed are a magnetic resonance temperature correction method based on k-space energy spectrum analysis and a system. The method includes: filling a k-space data matrix of magnetic resonance with zeros row by row, and performing an inverse Fourier transform on the k-space data matrix after filling each row of zeros, to obtain a reconstructed image; drawing a pixel intensity variation curve according to a pixel intensity of each pixel in all reconstructed images and a number of rows filled with zeros, and obtaining echo error according to the pixel intensity variation curve, calculation an actual echo time, and calculating a corresponding temperature variation value based on theof each pixel.
