[0048] Please refer to Figure 1 to Figure 4 As shown, a real-time tumor localization method of the present invention needs to use the following real-time tumor localization device 100, including:
[0049] Permanent magnet group 1, the ring is set around the tumor and close to the tumor;
[0050] The magnetic sensor array 2 is magnetically connected with the permanent magnet group 1, and is arranged on the upper or lower end of the patient's chest, and is used to measure the magnetic field intensity signals generated by the permanent magnet group 1 at various points in the magnetic sensing space;
[0051] The computer 3 is connected with the magnetic sensor array 2, and is used for data acquisition and processing of the magnetic field strength signal measured by the magnetic sensor array 2, and obtains the pose information of each permanent magnet based on the pose tracking algorithm, that is, the position and orientation information of each permanent magnet. 3D position and ...
