New high resolution radiation dose mapping of special type polymer-gel dosimeters using mini-MRI scanner of high (4.7 Tesla) magnetic field. Gel dosimeters main advantage is dose determination in 3-dimensions. Their main limitation is low spatial-resolution. We propose fabrication of special-type gels and for the first time use the 4.7 Tesla mini-scanner for dose mapping. Increased magnetic field combined with a small aperture for field dissipation will greatly improve spatial resolution down t ....New high resolution radiation dose mapping of special type polymer-gel dosimeters using mini-MRI scanner of high (4.7 Tesla) magnetic field. Gel dosimeters main advantage is dose determination in 3-dimensions. Their main limitation is low spatial-resolution. We propose fabrication of special-type gels and for the first time use the 4.7 Tesla mini-scanner for dose mapping. Increased magnetic field combined with a small aperture for field dissipation will greatly improve spatial resolution down to micrometers (micro-dosimetry). This new technique will render gel-dosimeters suitable for applications in radiotherapy, industrial and all other radiation fields. Moreover, we will employ new parameter for dose mapping, which is expected to be more sensitive to radiation than the currently used relaxation timesRead moreRead less
