Real-time monitoring of patient radiation exposure during diagnostic or therapeutic medical procedures is a crucial safety precaution, particularly in high dose or dose rate applications. Dosilab is currently developing a range of products for performing quality assurance and quality control procedures in high dose rate brachytherapy, and a first system is currently in clinical trials.
Securidose-BT High dose rate (HDR) brachytherapy uses a small, highly active radioactive source that generates strong dose gradients in its environment. Precise control of the radiation source’s spatial and temporal position is essential for successful treatment, so it is necessary to implement a quality assurance and quality control procedure.
To meet this need, Dosilab is developing a new generation of products based on patented technology from the Institute of Nanotechnologies Lyon (INL) at the University Claude Bernard in Lyon, developed in cooperation with the Hospices Civils de Lyon and the Centre Hospitalier Universitaire de Grenoble Alpes. This innovative technology uses miniaturized dosemeters made of gallium nitride (GaN) transducers that emit UV photons when exposed to ionizing radiation (radioluminescence).
Description Securidose-BT is an instrumented phantom that can be used to perform quality assurance procedures for HDR brachytherapy, in accordance with ESTRO recommendations (Booklet No. 8).
Securidose-BT measures the following parameters:
The position of the source and the length of the transfer tubing.
The pause time of the source
The activity of the source
The dose at specific points using the TG43 formalism.
Compares the measured results with the expected results using the DICOM file of the treatment protocol.
Stores the measurements made in a database. Thanks to this data set, potential deviations of the system can be detected. The respective reports can be downloaded as PDFs and consequently guarantee the traceability of the quality monitoring of a unit.
Measurements are made:
With quick set-up: Securidose-BT connection is fitted to the transfer tubes of the source afterloader and communication with system is remotely controlled via network

Where this is not already contractually agreed, we will inform you in advance.
The exercise of your rights requires that you prove your identity (e.g. by means of a copy of your identity card if your identity cannot otherwise be determined). If you incur any costs, we will inform you in advance.
In the area of data processing within the framework of dosimetry, you can only assert your rights to the extent that these can be granted within the framework of the statutory provisions on radiation protection and dosimetry (see also below).
Changes We reserve the right to amend this privacy statement at any time without prior notice. The current version published on our website applies.
3. Individual data processing operations
Data processing within the framework of the Radiation Protection Ordinance Dosilab AG is a personal dosimetry laboratory pursuant to Art. 66 et seq. of the Radiation Protection Ordinance (RPO). In this function, we are obliged pursuant to Art. 73 RPO to record the following personal data of persons exposed to radiation (Art. 51 RPO):
Name and first name (incl. previous names) of the person recorded
Date of birth, sex and social security number
Name, address and UID of the enterprise
Occupational group, activity and category
Dose values determined in Switzerland and abroad over the entire monitoring period
