From our president

Triangle Products had been started in 2010. Our theme is 「Be simple in radiothrapy QA」 and we has developed several software programs. Triangle Products starts a new project. The theme is 「Be ‘simple’ in complex measurements」. One of the services in the project is postal audit for high-dose-rate brachytherapy using a gel dosimetry. The gel dosimetry service will solve your problems of complex high-dose-rate brachytherapy measurements and provide high quality postal audit. This service will cover the comprehensive postal audit covering gel dosimeter itself, magnetic resonance imaging and dose distribution analysis. We strongly believe that this service will be a good help to provide the safe treatment to your patients.

In addition to it, we will help your application of gel dosimetry to clinical practices and research. We discuss your request and provide you our gel dosimeter and magnetic resonance imaging.

We has been the first company to provide the gel dosimetry service in Japan (June, 2019) and are feeling a big responsibility. We would like to support your precise radiotherapy technologies.

Corporate Policy

  1. We provide high quality gel dosimeter and steady gel dosimeter supply.
  2. We provide end-to-end gel dosimetry process covering gel dosimetry, shipping, magnetic resonance imaging and dose distribution analysis.
  3. We contribute to radiation therapy via our gel dosimetry services to prevent brachytherapy accidents.
  4. We facilitate to use gel dosimetry in clinical practices and research.

Postal audit for high-dose-rate brachytherapy using a gel dosimetry entrusted by the RTHG

Dose distribution evaluation is not common in high-dose-rate brachytherapy using ionization chamber, film, multi-array detectors used for intensity-modulated radiotherapy because steep dose gradient for Ir-192 source makes us difficult for the measurements. Thus, single measurement setup cannot be used in quality assurance for high-dose-rate brachytherapy. Our company provides a comprehensive gel dosimetry service covering gel dosimeter, shipping, magnetic resonance imaging and dose distribution analysis. Just one setup and one irradiation are needed for this service. The quality assurance will be simple and also cover the verification of air kerma strength and dwell position for high-dose-rate brachytherapy. The service is useful for the source exchange and scheduled quality assurance works.

Application of a gel dosimetry to clinical practices and research

The manufacturers providing gel dosimeters are few in the world. You must make gel dosimeter by yourself to achieve your target in clinical practices and research. In addition to it, you must determine magnetic resonance imaging sequence by yourself and perform the image acquisition. Gel dosimeter must be made with several reagents while the agents are sensitively measured. In addition to it, gel dosimeter is sensitive to temperature and the imaging sequence. For your help, our company provides high quality gel dosimetry process.

  • We will provide gel dosimeter in response to your request.
  • At first, you and we discuss your request including gel dosimeter and container. Magnetic resonance imaging is optional.
  • After the discussion, you transfer the container, we will fill the gel in the container and return the container with the gel. After irradiation, we will use magnetic resonance imaging to obtain the images of the irradiated gel if you need and transfer it.
  • The fee of the first order includes the fee of gel dosimeter, shipping including the discussion.
  • After the second order, the fee is only for gel dosimeter, optional magnetic resonance imaging and shipping.
  • The fee of the imaging is added if you choose the magnetic resonance imaging.
  • The fee of the gel dosimeter is dependent on the amount of the gel dosimeter.
