Method and system for compensating a self-caused displacement of tissue

摘要

A system for compensating a neurally triggered or other self-caused displacement of a tissue of an animal including man comprises a base provided with a means for immobilizing the animal or body part thereof comprising the tissue, one or more displacement means in contact with the base, a means for sampling position data from a marker disposed in or in the proximity of the tissue, a means for sampling source activity data from one or more sources of displacement, microprocessor means for correlating position data and source activity data to generate a predictive correspondence, a means for controlling the one or more displacement means by source activity data based on the predictive correspondence. Also disclosed is a corresponding method and use.

1. A method for compensating a neurally triggered or other self-caused displacement of a tissue of an animal including man, comprised by a body part disposed, in a fixed relationship, on a base in contact with a displacement apparatus, the method comprising:
(a) disposing an index marker in or in the proximity of the tissue or identifying, as an index marker, a structure in or in the proximity of the tissue; (b) sampling position data from said index marker or from said structure; (c) sampling source activity data from one or several sources of displacement; (d) correlating the position data and the source activity data to generate a predictive correspondence of the position data and the source activity data; (e) controlling the displacement apparatus in response to the predictive correspondence so as to displace the base in a manner compensating the predicted neurally triggered or other self-caused displacement of the tissue and thereby control the actual position of the body part tissue which has a fixed relationship with the base; (f) updating the predictive correspondence in intervals or continuously.
