Patent ID: 8391570

Claim:
A method for locating a disordered tissue in a human body or animal body, such as a tumor, and for guiding an irradiation equipment located outside the body for treatment of the disordered tissue in the body, comprising the steps of: initially performing one of the following steps: inserting into a cavity of the human body or the animal body, or maintaining in position in a cavity of the human body or the animal body, at least one single, integral three-dimensional element, the at least one three-dimensional element having a locking mechanism for locking the three-dimensional element in a position relative to the disordered tissue so as to ensure that the three-dimensional element will have substantially no movement relative to the disordered tissue, and the at least one three-dimensional element having a geometrical structure with a number of points that are detectable in an image of the three-dimensional element, identifying, in an image, the at least one single, integral three-dimensional element visible in the image of the human body or the animal body in relation to the disordered tissue, establishing, in the image, a preliminary position of the at least one single, integral three-dimensional element, visible in the image, in relation to a reference, establishing, in the image, a preliminary position of the irradiation equipment in relation to the reference, in order to establish a preliminary set-up of the irradiation equipment in relation to the reference, and adjusting the irradiation equipment in relation to the reference in response to the preliminary position or a subsequent position of the at least one single, integral three-dimensional element in relation to the reference.
