When enabling dose to water i get Nan values in some of the voxels in the water region of my phantom. I also get different values in the water voxels between both dose reports (dose to medium and dose to water). It seems like there's a bug when gate tries to converts dose to medium into the dose to water when in the water region. Has anyone already faced this problem? Any help would be much appreciated. Kind Regards, Tony Younes </body> </html>
