Abstract: The present invention relates to a method and an apparatus for guiding an irradiation equipment (2) located outside a human body (1) or an animal body. The method comprises the steps of identifying, in an image (4), a three-dimensional element (7) visible in the image (4), said three-dimensional element (7) has been in position in, or being inserted into, a cavity of the human body (1) or the animal body, establishing, in the image (4), a preliminary position of the three-dimensional element (7) visible in the image (4) in relation to a reference, establishing a preliminary position of the irradiation equipment (2) in relation to the reference, and adjusting the irradiation equipment (2) in response to the position the three-dimensional element (7).

Abstract: The present invention relates to a method and an apparatus for identification of an element in two or more images. The method comprises the steps of, identifying, in an image an integral three-dimensional element visible in the image, and identifying in a first image the three-dimensional element, identifying in a second image the three-dimensional element. Subsequently, collating is performed based on the first image and the second image and based on a determination of the position of the three-dimensional element in the first image and the position of the three-dimensional element in the second image. Thereby, a position and/or an extension in three dimensions of a bodily matter of interest within the human body or the animal body may be established.
