An equatorial anthropic radiation source and a method of making an equatorial anthropic radiation source are described. The radiation source is useful in diagnostic imaging applications in healthcare or other industries (e.g. computerized three-dimensional segmental imaging; Crompton scattering imaging techniques; radiation detector check and calibration, in particular CdZnTe detectors commonly used in medical imaging).

Radiation source including osmium

Method of manufacturing a radiation source

A radioactive member for use in brachytherapy comprising a molded elongate, bioabsorbable carrier material with spaced radioactive sources disposed therein, and methods for the manufacture thereof. The radioactive members may be used in the treatment of, for example, prostate cancer.

Radioactive member and method of making

An apparatus for welding closed one end of each of a multiplicity of open-ended tubes suitable for use as brachytherapy capsules includes a welding station having a welding position for welding closed one end of a tube, a rotatable platform having an outside edge, a tube holder positioned adjacent the outside edge, the tube holder movable between a loading position and the welding position, and a feed line positioned in overlying registry with the tube holder at the loading position.

Welding method and apparatus

A radioactive member for use in brachytherapy comprising a molded elongate, bioabsorbable carrier material with spaced radioactive sources disposed therein, and methods for the manufacture thereof. The radioactive members may be used in treatment of, for example, prostate cancer.

A radioactive member for use in brachytherapy comprising an essentially stiff elongate, single stranded bioabsorbable carrier material with spaced radioactive sources disposed therein, and methods for the manufacture thereof. The radioactive members may be used in the treatment of, for example, prostate cancer.

Products and methods for brachytherapy

In a method for welding closed one end of each of a multiplicity of open-ended tubes suitable for use as brachytherapy capsules ( ), each tube is loaded into a holder ( ), brought to a welding station ( ), has one end welded closed and is then released from the holder ( ). A number of holders can 2 be arranged on the periphery of a rotatable member ( ), each holder being loaded with a tube at a first station, and then carrying the tube to a welding station ( ) and an ejection station ( ). The tubes can be loaded into the holders individually by means of an escapement mechanism ( ). The invention also extends to apparatus for carrying out the method.
