BSD-2000 3D/MR Independent Quality Study
An independent quality assurance study of the five clinical BSD-2000-3D/MR systems has been published in the International Journal of Hyperthermia by H. Mulder et al. the study intended to validate the accuracy and consistency of the deep heating focus and electronic steering of this system. The study test results concluded, on these five separate systems, that “the Pyrexar Medical BSD2000-3D MR compatible applicator provides robust and reproducible heating.“ The study found that the heating characteristics were reproducible within a 95% confidence interval of 0.4˚C. Based on these evaluations, the applicator was approved for clinical use. This study further made it clear that these BSD-2000 systems provide deep selective heating focus to the center of the body equivalent phantom along with the electronic steering precision.
• Applicator provides robust, reproducible heating
• 95% confidence interval of 0.4˚C
• Selective heating focus with electronic steering precision
• 5 MR-based Hyperthermia Systems already Installed
Why is this important?
1) It shows that our systems design and manufacturing is solid, even in the most sophisticated products; 2) When designing a multi-hospital, multi-country clinical study, there is hardware reliance; and 3) The research community continues to invest its time in system validation, necessary to maintain standards that industry should follow.
About the BSD-2000 3D/MR
Pyrexar Medical manufactures the most advanced hyperthermia treatment systems in the world. The model BSD-2000-3D/MR can focus radiated RF power to deep sites in the body with 3D electronic steering. Further unique advancement of this configuration is that it has been integrated with magnetic resonance imaging (MRI), which has been adapted to display non-invasive temperature change images during the elevated temperature treatments. This unique system provides image-guided thermal therapy of deep tumors within the patient’s body.
This excellent quality assurance study is vital to our goal of assuring high quality hyperthermia cancer treatments and to allow for results of clinical studies, at various centers around the world, to be combined in future clinical research.
