Abstract: According to an exemplary embodiment of the present disclosure, a determination of a (floating) isocenter of a radiotherapy system can be provided. For example, the radiotherapy system can comprises a patient support structure, a gantry configured to be rotatable around a gantry axis and having a radiation source, and at least one radiation imaging device. The system can include a calibration system comprising at least one first optical detector mounted at the gantry, at least one second optical detector fixed in a surrounding area of the patient support structure and/or the gantry, first fiducial markers selectively attachable at the patient support structure at defined positions and detectable by the first optical detector, and a phantom selectively attachable at the patient support structure at a defined position. The phantom can include second fiducial markers detectable by the second optical detector, and third fiducial markers configured to be detectable by the radiation imaging device.

Abstract: A device for implanting radioactive seeds and non-radioactive spacers in a desired configuration in an animal body for effecting radiation therapy. An elongated hollow needle is inserted in the body. A pushing element implants the row of seeds and spacers though the hollow needle towards the desired location. A tube shaped element receives the row of seeds and spacers. A lube shaped sleeve having open ends is used to insert the tube shaped element through the needle and toward the location. The pushing elements pushes the row of seeds and spacers into the desired location while still being carried in the tube shaped element.

Abstract: The invention relates to a device for implanting at least one row of X radioactive seeds and Y non-radioactive spacers with X?[1, 2, . . . ] and Y?[0, 1, . . . ] in a desired configuration to a desired location in an animal body for effecting radiation therapy of cancerous tissue in said body, said device comprising: at least one elongated hollow needle with an open distal end to be inserted towards said desired location in the body and with a proximal end to be connected to a seed loading apparatus; and at least one pushing element for implanting during retraction of the elongated hollow needle said row of radioactive seeds and non-radioactive spacers from said seed loading apparatus through said hollow needle towards said location.
