Afterloading device, and use thereof

An afterloading system for performing a brachytherapy-related procedure, comprising:

• an afterloader device for delivering radiation treatment;
• a first elongated flexible element for maneuvering a radiation source from a source storage position located inside of the afterloader device to a first source position located outside of the afterloader device;
• a second elongated flexible element including at least one transducer for detecting a parameter indicative of a pre-determined radiation source position and generating a position signal, and wherein the second element moves the at least one transducer from a first transducer position to a second transducer position at which the transducer may detect the parameter indicative of the radiation source position,
• wherein the transducer communicates the position signal to the afterloader device.

A method of verifying the position of a radiation source during a brachytherapy-related procedure, comprising:

• moving a distal end of a first elongated element to position a radiation source, attached to the first elongated element, at a first location within a brachytherapy device placed within a body of a patient;
• moving a distal end of a second elongated element to position a transducer, attached to the second elongated element, at a second location within the brachytherapy device, wherein the second location is a predetermined distance away from the first location;
• detecting, by the transducer, a parameter reflecting a position of the radiation source and generating a position signal;
• and
• determining, by the controller, and based on the generated position signal, a movement of the first element in order to position the radiation source.
