The Utrecht University Medical Centre in the Netherlands is working to ensure that photon rays used in radiation therapy are conducted more accurately. They are based on magnetic resonance imaging.

The possibility of combining both techniques has been demonstrated by a slight adaptation of the MRI instrument and the accelerator used for radiation therapy. On the one hand, the components of the magnetic resonance have been modified to produce a weaker magnetic field in the work area of the accelerator, and on the other hand the steel components of the accelerator have been replaced by non-magnetic ones to avoid the influence of the magnetic field generated by the magnetic resonance apparatus.

Once molded, the resonance imaging is observed to be identical when the radiation beam for radiation therapy is working and not. Thus, it has been proven that radiation has no effect on resonance.

A possible resonant continuation of the radiotherapy ray would allow a lot of treatment to be defined, reducing side effects and avoiding radiating vulnerable tissues present in damaged tissues.
