Embodiment Construction

[0009] The output flexible wire of the miniature coil (1) is connected to the A / D conversion amplifier (2) through the connector, and then connected to the multi-channel signal processor (3) through the output wire, and then connected to the computer (5) through the output wire connector. The magnetic field generator (4) is connected to a 220V power supply to generate a 3-dimensional magnetic field. Under the action of the 3-dimensional magnetic field, the microcoil (1) generates an induced current, which is input to the multi-channel signal processor through the A / D conversion amplifier (2) (3) Finally input it into the computer (5), and the 5 degrees of freedom and coordinate points of the microcoil (1) can be displayed on the display (6).

[0010] Use a puncture needle (8) to implant N (N ≥ 1) microcoils (1) with output flexible wires into the lesion area (10) of the human body, and the output flexible wires of the microcoils (1) stay on the patient's body surface In additi...

Abstract

The present invention provides a real-time tracking location system. It is characterized by that based on electromagnetic induction principle and graphic image processing technique said invention combines them with focus of human body so as to make dynamic assignment and real-time tracking of human body internal organs and focus, and in the insertion therapy and medical accelerator, cobalt 60 machine and external irradiation of gamma-knife it can implement real-time tracking operation of focus.

Description

technical field [0001] The present invention proposes a real-time tracking and positioning device, which is based on the principle of electromagnetic induction, the combination of graphics and image processing technology and human lesions, and is especially suitable for dynamic calibration and real-time tracking and positioning of human internal organ lesions. The focus area is tracked in real time during the external irradiation of cobalt 60 machine and gamma knife. Background technique [0002] At present, γ-rays and X-ray external irradiation are used to treat malignant tumors. Gold particles are implanted in the lesion area of ​​the patient, and the marked points of the lesion area are displayed under CT. During the treatment, the movement of the marked points is tracked by the digital X-ray machine, and then the signal is input to the treatment equipment for tracking and positioning. This is the most advanced real-time positioning and tracking system of Variant in the ...
