Method and apparatus for performing image guidance, medical equipment, and computer-readable storage medium

An apparatus for performing image guidance, comprising:

• a processor and a memory storing program instructions therein, wherein the processor is configured to execute the program instructions in the memory to perform a method for performing image guidance, wherein the method comprises:
• acquiring a 3D magnetic resonance (MR) image of a target individual, wherein at least one region of interest is marked in the 3D MR image;
• acquiring a reference 3D image of the target individual, wherein the reference 3D image is a 3D-reconstructed computed tomography (CT) image;
• performing a 3D-3D registration on the 3D MR image and the reference 3D image to transform the at least one region of interest in the 3D MR image into at least one region of interest in the reference 3D image, so as to mark each region of interest in the reference 3D image;
• and
• performing image guidance on a basis that the reference 3D image is adopted to characterize an initial position state of the target individual, at least one region of interest marked in the reference 3D image and transformed from the at least one region of interest in the 3D MR image being used to determine a reference position of a target volume at a start moment of a treatment activity.

A non-transitory computer-readable storage medium, storing a computer program therein, wherein the computer program comprises program instructions, and the program instructions, when executed by a processor, causes the processor to perform a method for performing image guidance comprising:

• acquiring a 3D magnetic resonance (MR) image of a target individual, wherein at least one region of interest is marked in the 3D MR image;
• acquiring a reference 3D image of the target individual, wherein the reference 3D image is a 3D-reconstructed computed tomography (CT) image;
• performing a 3D-3D registration on the 3D MR image and the reference 3D image to transform the at least one region of interest in the 3D MR image into at least one region of interest in the reference 3D image, so as to mark each region of interest in the reference 3D image;
• and
• performing image guidance on a basis that the reference 3D image is adopted to characterize an initial position state of the target individual, at least one region of interest marked in the reference 3D image and transformed from the at least one region of interest in the 3D MR image being used to determine a reference position of a target volume at a start moment of a treatment activity.
