DESCRIPTION provided by applicant This NIH Bridge Grant will result in a conduction cooled liquid helium free MRI background magnet for a commercial image guided radiation treatment IGRT for cancer treatment The program will ensure the successful continued commercialization of our customerandapos s image guided radiation therapy IGRT system a vital cancer treatment device now treating patients The result of the project removes our customerandapos s present system from its dependence on liquid helium the availability of which is threatened by worldwide shortages in the next few years The cancer treatment system makes available image guided radiation therapy IGRT that delivers gamma radiation in real time to malignant tumors with pinpoint accuracy in spite of organ movement This is realized with the concurrent real time radiation treatment and MRI imaging The results of this Bridge Grant through Hyper Tech makes possible the uninterrupted progress of this vital technology by providing a helium free cryocooled background magnet based on our magnesium diboride MgB superconducting wire These MgB magnet systems will not only significantly lower the initial cost but will reduce on going service costs of our customerandapos s image guided radiation therapy system In addition the magnet system will be safer and less prone to quenching These magnets will replace the current liquid helium bath dependent niobium titanium NbTi superconductor background magnets in the MRI system During the project we will complete and finalize the modelling and design complete detail drawings fabricate the magnet components and the superconductor wire We will wind and test the individual coils in the system We will fabricate assemble and test the magnet system and deliver it to our customer for integration and testing into their image guided radiation therapy system PUBLIC HEALTH RELEVANCE This project will facilitate designing building and integrating a conduction cooled MRI background magnet for our customerandapos s commercial image guided radiation therapy IGRT system a vital treatment device for treating cancer patients It removes the present system from its dependence on liquid helium the availability of which is threatened by worldwide shortage The first of a kind prototype of Hyper Techandapos s helium free MgB based MRI magnet for our customerandapos s IGRT device will come out of this NIH Bridge Grant This IGRT system for cancer treatment makes available IGRT that delivers gamma radiation in real time to malignant tumors with pinpoint accuracy in spite of organ movement This is realized with the concurrent real time treatment and MRI imaging These MgB magnet systems will not only significantly lower the initial cost but will reduce on going service costs of our customerandapos s IGRT systems In addition the magnet system will be safer and less prone to quenching and will enable our customer to avoid the predicted shortage and rising cost of liquid helium
