Method and system for registering a medical situation associated with a first coordinate system, in a second coordinate system using an MPS system

Method for re-positioning a portion of the body of a patient during a multi-session automatic therapeutic procedure, the method comprising the procedures of:

• detecting an initial position and orientation of said position and orientation detector that is fixed in the body at a selected location in a spatial relation with selected tissue, during a first therapeutic session, wherein said initial position and orientation is associated with a therapeutic position and orientation, suitable for automatically retreating said selected tissue of said body;
• recording said initial position and orientation;
• detecting, while said detector remains fixed at said selected location, the current position and orientation of said position and orientation detector, at the beginning of a further therapeutic session after said initial therapeutic session, wherein said detector remains in the body during a treatment period under which the patient is under medical treatment;
• and
• producing a notification when said current position and orientation is substantially the same as said recorded initial position and orientation during subsequent treatment sessions.

System for medically retreating at different times a selected tissue within the body of a patient, the system comprising:

• a first medical positioning system configured to detect a first position and orientation of a position and orientation detector relative to a first coordinate system when said position and orientation detector is coupled with said first medical positioning system, said first medical positioning system configured to store said first position and orientation in a storage unit, said position and orientation detector being located at a selected fixed location in a spatial relation with said selected tissue, said first medical positioning system being coupled with an imager and said imager configured to produce at least one image by associating said at least one image with said first position and orientation;
• a second medical positioning system, said second medical positioning system being separate from said first medical positioning system, said second medical positioning configured to detect a second position and orientation of said position and orientation detector relative to a second coordinate system when said position and orientation detector is coupled with said second medical positioning system, said second medical positioning system being coupled with a therapeutic device, said therapeutic device being different from said imager;
• and
• a registering module coupled with said storage unit, said second medical positioning system and with said therapeutic device, said registering module registering a set of coordinates of said selected tissue in said first coordinate system, with said second coordinate system, said set of coordinates being associated with said first position and orientation, said therapeutic device medically retreating said selected tissue according to said registered set of coordinates.

Method for medically treating at different times a selected tissue within the body of a patient, the method comprising the procedures of:

• detecting a first position and orientation of a detector in a first coordinate system, by a first medical positioning system (MPS) wherein said first MPS is coupled with an imager, said detector being located at a fixed selected location in a spatial relation with said selected tissue;
• associating a set of coordinates of said selected tissue in said first coordinate system, with said first position and orientation;
• detecting a second position and orientation of said detector in a second coordinate system, by a second medical positioning system (MPS) wherein said second MPS is associated with and coupled with a therapeutic device;
• registering said associated set of coordinates with said second coordinate system, according to said second position and orientation;
• medically treating said selected tissue with said therapeutic device according to said registered set of coordinates.
