Method and system for determining location of subject or surgical tool

A system for determining a location of a subject or a surgical tool, the system comprising:

• an X-ray device comprising a plurality of X-ray sources configured to irradiate the subject with X-rays and an X-ray detector configured to detect X-rays transmitted through the subject;
• a memory storing respective location coordinates of the plurality of X-ray sources and the X-ray detector in a first coordinate system of the system;
• and
• a processor configured to:
• obtain a three-dimensional medical image of the subject from an external device;
• obtain a plurality of first X-ray images of the subject using the X-ray device;
• match a second coordinate system of the three-dimensional medical image to the first coordinate system based on the respective location coordinates of the plurality of X-ray sources and the X-ray detector in the first coordinate system, the plurality of first X-ray images, and the three-dimensional medical image;
• determine location coordinates of the subject in the first coordinate system based on the matching result;
• obtain a plurality of second X-ray images of the surgical tool comprising an electrode using the X-ray device;
• and
• determine location coordinates of the surgical tool in the first coordinate system based on the plurality of second X-ray images.

A method for determining a location of a subject or a surgical tool of a system comprising an X-ray device that comprises a plurality of X-ray sources configured to irradiate the subject with X-rays and an X-ray detector configured to detect X-rays transmitted through the subject, a memory, and a processor, the method comprising:

• receiving a three-dimensional medical image of the subject from an external device;
• obtaining a plurality of first X-ray images of the subject using the X-ray device;
• matching a second coordinate system of the three-dimensional medical image to a first coordinate system based on respective location coordinates of the plurality of X-ray sources and the X-ray detector in the first coordinate system of the system, which are stored in the memory, the plurality of first X-ray images, and the three-dimensional medical image;
• determining location coordinates of the subject in the first coordinate system based on the matching result;
• obtaining a plurality of second X-ray images of a surgical tool comprising an electrode using the X-ray device;
• and
• determining location coordinates of the surgical tool in the first coordinate system based on the plurality of second X-ray images.
