"You don't do an online music store to make money," he said. "When everyone is zigging, that's when you want to zag. "I definitely would not down play that I am an entrepreneur, Robertson said. Can you trust the authenticity of this blond haired, laid back executive who was raised in Los Angeles and does business in San Diego? Can you trust the motives of his battles with the likes of Microsoft and the recording industry? Is this altruism, capitalism, entrepreneurism or greed? We sat down this week here at the Linspire-sponsored Desktop Summit to try and answer some of these questions and to talk to Robertson about his latest venture - a DRM-free online music shop called MP3tunes. It just raises immediate questions about someone like Michael Robertson of Linspire, MP3.com and SIPphone fame. Half of the people aren't even real people at all - they're actors. The cities are filled with bland, repetitive strip malls loaded down with chain restaurants not local cuisine. The water is fake - pumped in from far away reservoirs. Accuracy of multi-modality DIR in MRIdian was comparable to MIM maestro.Desktop Summit There is a shallowness to Southern California culture that can make you question the authenticity of anything coming out of the place. And those of Jaccard coefficient were 0.85, 0.038 in MRIdian and 0.89, 0.019 in MIM.Ĭonclusion: Dice coefficients and Jaccard coefficients were calculated to evaluate the DIR accuracy of MRIdian and MIM. The means and the standard deviations of Dice coefficient for left kidney in five patients were 0.92, 0.014 in MRIdian and 0.94, 0.012 in MIM, respectively. And those of Jaccard coefficient were 0.80, 0.091 in MRIdian and 0.87, 0.017 in MIM. The means and the standard deviations of Dice coefficient for right kidney in five patients were 0.89, 0.060 in MRIdian and 0.93, 0.010 in MIM, respectively. And those of Jaccard coefficient were 0.86, 0.021 in MRIdian and 0.85, 0.013 in MIM. Results: The means and the standard deviations of Dice coefficient for liver in five patients were 0.93, 0.014 in MRIdian and 0.92, 0.007 in MIM, respectively. Dice coefficient and Jaccard coefficient were calculated with the structure on MR as a reference. Structure delineation was performed in MR image, deformed CT images by MRIdian and by MIM. The multi-modality DIR based on MR image was done with MRIdian and MIM. Clinical images were only used in this analysis. CT images were acquired by Aquilion LB (CANON MEDICAL SYSTEMS CORPORATION) to assign electron density map on MR images by DIR procedure. Methods: MR images were acquired by MRIdian for image-guide.
Our purpose is to evaluate the accuracy of multi-modality deformable image registration (DIR) in MRIdian by comparison to other DIR software MIM maestro (MIM Software Inc.).
Fusion of magnetic resonance (MR) image and computed tomography (CT) image was necessary to calculate dose distribution on-table ART in MRIdian. Purpose: MRIdian (Viewray Inc.), the magnetic resonance image guided radiotherapy (MR-IGRT) system, allows us on-table adaptive radiotherapy (ART).
