摘要： Test device for testing proper positioning of a radioactive radiation source for brachytherapy in an applicator tip, said device comprising

a base device containing

at least one, preferably at least two radiation detector(s),
at least one, preferably at least two channel(s) for guiding radiation,
at least one, preferably at least two opening(s) in the surface of the base device, each channel connecting one radiation detector with one opening in the surface of the base device, and

an applicator holder comprising a cavity for receiving the applicator tip, including the radioactive radiation source, said applicator holder further including at least one, preferably at least two opening(s), which is/are arranged to match the opening(s) in the base device, and at least one, preferably at least two collimating channel(s), which channel(s) form(s) extensions of the channel(s) in the base device through the opening(s) in the base device, and which channel(s) connect(s) separate points of the cavity with the opening(s) in the applicator holder to guide and collimate radiation emitted in separate positions of the cavity to the respective radiation detector, one of which points is located at the distal end of the cavity. Preferably the applicator holder is separate from the base device, this embodiment allowing for sterilization of the holder before insertion of the applicator tip.
