ABSTRACT:
There is provided an apparatus for effecting radioactive therapy in an animal body. A radioactive source assembly is disposed in a source channel, and a test assembly is disposed in a test channel. A source connecting tube is attached to the source channel and to a connector, and a test connecting tube is attached to the test channel and to the connector. A guide transfer tube is connected to the connector and an other end thereof is disposable at the site in an animal body intended for therapy. A source assembly transport thread is connected to the source assembly and a test assembly transport thread is connected to the test assembly. A source drive means is connected to an other end of the source transport thread and a test drive means is connected to an other end of the test transport thread. The source drive means and the test drive means are operable such that alternatingly the source assembly and the test assembly may be moved from the respective channels and through the guide transfer tube to the site of intended therapy. With this arrangement, the movement of the test assembly to the site of intended therapy is comparable with the movement of the source assembly to the site of intended therapy, whereby the correct positioning of the source assembly at the site of intended therapy is confirmable.
