1 The Magnetic Stereotaxis System(MSS) is a unique medical device designed to deliver drugs and other therapies directly into the bodies to perform complicated surgical operations.

2 Intensity modulation, image-guided, stereotaxis and minimal invasive interstitial intervention radiotherapy show incomparable advantages and application prospect.

3 Methods: Stereotaxis instrument and RM-6240B biological signal collecting and processing system were used to measure SEP of the rabbits before and after internal capsule hemorrhage.

4 The Magnetic Stereotaxis System (MSS) is a unique medical device designed to deliver drugs and other therapies directly into deep brain tissues to perform complicated surgical operations.

5 Objective To investigate the value of X-ray Knife in the stereotaxis radiotherapy of lung cancer.

6 Conclusion: The three dimensional form and position of the reconstructed amydaloid nuclei have reference value to the stereotaxis technique of encephalon.

7 As the improving of CT scanning technique, the use of stereotaxis technique and the development of pathology, CT-guided percutaneous needle biopsy was expected to further extend.

8 This paper is mainly focused on detecting the space position of the object in Magnetic Stereotaxis System (MSS).
