Abstract

The invention discloses a magnetic resonance scanning positioning system and a directivity positioning scanning method. The magnetic resonance scanning positioning system comprises a control center, an optical measurement system, display equipment and a positioner, wherein the optical measurement system and the display equipment are connected with the control center; a passive identification ball group capable of being tracked by the optical measurement system is arranged on a positioner detachably connected with a collimator; a pilot hole allowing penetration of a puncture needle is formed in the collimator in the axial direction; and the collimators with pilot holes of different inner diameters are correspondingly matched with the puncture needles in different thicknesses and are the same in dimensions. The magnetic resonance scanning positioning system can perform directivity positioning scanning to present real-time scanning images. The invention further provides a method which brings convenience in guidance, integral observation, and quick rectification.

Description

technical field [0001] The invention relates to the magnetic resonance medical field, in particular to a magnetic resonance scanning positioning system and a directional positioning scanning method. Background technique [0002] Interventional therapy is a major development direction of modern medicine. The difference between interventional therapy and traditional surgery is that it does not require surgery, and only needs a small incision to insert special catheters, freezing needles, radiofrequency ablation needles and other puncture needles. Go to the lesion site or surgical target in the human body, and then achieve the purpose of treatment through various physical or chemical effects, so as to solve the problems of tumor treatment, tissue biopsy, artificial equipment or drug placement that could only be solved by open surgery in the past. [0003] During the interventional treatment, doctors cannot directly observe the tissue structure and lesion in the patient, and can...
