Elekta introduces the first commercial high-field MR-linac system

The popular Swedish manufacturer of radiosurgery, radiation therapy, and brachytherapy systems, at last, is introducing a magnetic resonance imaging scanner and linear accelerator therapy in one combined system. Yes! You are right. We are taking about Elekta. Various engineers and physicists considered that this might not be possible since rapidly moving particles, which are charged in nature, bombarding out of an accelerator are sturdily impacted by a magnetic field. However, scientists at a huge research center in Holland, UMC Utrecht, had a number of fresh thoughts and they constructed the initial model way back, showing the probable wrong things, and this led to a procedure compelling Elekta to operate along with Philips on designing a marketable MR-linac tool.

Depending on a Philips 1.5 Tesla MRI machine, the new Elekta Unity MR-linac creates an image quality that is at a diagnostic level during therapy sessions. This permits for more accurate treatment, counting superior doses focusing sensitive sections having different organs, and instant surveillance of how the radiation impacts the tumor. Older systems depended on low-field MR, which is not enough to create crisp as well as is not simple to examine images.

When speaking with the CEO of Elekta, Richard Hausmann, about learning more about this innovative new system, he claimed that an MR-linac reminds you of a conventional cathode ray tube in which electrons are aimed at various sections of the screen by modifying the power of the magnetic fields that they fly within. Whereas this method assists in creating an image on a cathode ray tube television, a magnet close to an extremely focused electron ray curves it in redundant directions. It took quite a bit of calculating and engineering to line up different elements to efficiently reduce the magnet’s impact on the beam of the electron.

Fundamentally, the flow of blood through the tumor can be estimated, which specifies whether the tissue has succumbed to the therapy or is still well and alive. Although this is by now obtainable on the Unity, Hausmann thinks it will take some time for engineers to get familiar with operating the functions and to get trained to apply it in various conditions.
