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.
A method for positioning in a tissue a radiation seed via a hollow needle in accordance with an established treatment plan, wherein the established treatment plan is a plan of the types and coordinate positions of the seeds to be used to treat the tissue, said method comprising the steps of:
An apparatus for positioning radiation source seeds, spacer seeds and stoppers in a hollow needle and for discharging the same from the hollow needle, comprising:
