Abstract: Method and system, for which can be used in the fields of medicine and dentistry as well as for the most varied types of material working in different areas of application and model working, provides that an exact removal of material or a highly precise, reproducible material working can be realized by acquiring, storing and processing data pertaining to position and/or orientation of an effector and their changes relative to the position of at least one reference body. The effector is controlled and/or regulated with regard to its power and/or parameterization based on a predetermined working volume, material volume removed and remaining material volume. A first marking support with markings is arranged on a handpiece with the effector, where the handpiece is connected to a control unit, and a second marking support with markings is attached to the material object or tissue object.

Abstract: The invention relates to a method and device system, which are provided for removing material or tissue or for working material or tissue and which can be used in the fields of medicine and dentistry as well as for the most varied types of material working in different areas of application and model working. The invention is particularly advantageous in that an exact removal of material or a highly precise, reproducible material working can be realized within the shortest amount of time by acquiring, storing and computer processing data pertaining to position and/or orientation of the effector and their changes relative to the position of at least one reference body.

Abstract: A method for the positioning of radiation source seeds, spacer seeds and stoppers in tissue using hollow needles. Various seeds that are separately contained in magazines according to the isotope type (e.g., material, dosage, half-life period), are provided to the hollow needle. The individual magazines may be changed by means of a magazine changer. The magazine changer is located in a changer guide in a position which is vertical relative to the direction of injection of the seeds. The location of the needle is measured relative to a location reference block. An optimal seed deposit position is detected acoustically and/or visually and/or in a tactile manner. The selection of a magazine and a seed to be discharged from the magazine is derived from the current position of the needle in the tissue and from a treatment plan for a dosage distribution, which may be established in list form with details on the seed type and the x-y-z-coordinates relative to the location reference block.
