Outline of Final Research Achievements

High-dose-rate brachytherapy has multiple manual procedures which are prone to the human error, especially, during the connection process of the treatment device to applicator, which is when considerable attention is required.In this study, we propose a new connection verification device concept.The system is composed of a ring magnet, hole device and an in-house software. The magnetic field distribution is affected by the check cable position and any magnetic field variation is detected by the hole device. The value of the hole device is altered, depending on the location of the check cable. There was a reduction in sensitivity of the hole device, in our test, which was linked to the distance of the hole device from the check cable.We demonstrated a new concept of connection verification in a brachytherapy. This system has the possibility to detect an incorrect connection.
