G maps10/12/2023 We validate the method in 3× slice-accelerated spin-echo and gradient-echo EPI at 3T and 7T using 32-channel RF coil brain arrays. This achieves the desired shifts but avoids an undesired “tilted voxel” blurring artifact associated with previous methods. The shift between the slices is induced using sign- and amplitude-modulated slice-select gradient blips simultaneous with the EPI phase encoding blips. We introduce a method to create inter-slice image shifts in the phase encoding direction to increase the distance between aliasing pixels. However, the unaliasing of simultaneously acquired, closely spaced slices can be difficult, leading to a high g-factor penalty. Google announced plans to roll Immersive View for routes out to 15 cities around the world by the end of the year: Amsterdam, Berlin, Dublin, Florence, Las Vegas, London, Los Angeles, Miami, New York, Paris, San Francisco, Seattle Tokyo, and Venice.Simultaneous multi-slice EPI acquisition using parallel imaging can decrease the acquisition time for diffusion imaging and allow full-brain, high resolution fMRI acquisitions at a reduced TR. You’ll get all that info through a multidimensional experience that, as the name might suggest, is rather immersive.Įven better, the feature also tells you what the weather is expected to be like when you plan to travel and offers a time slider where you can see how the weather might change throughout the day.Īs complex as this sounds, we're not surprised to learn that it’s unfortunately not going to be available everywhere straight away. Maps will tap into information like where the bike lanes and public parking opportunities are, as well as data about complex intersections and traffic simulations, to give you an idea of how traffic typically looks in the area at the time of day you’re traveling using historical data.
