The panels represent the following cases: a dense acquisition, complete angular coverage and correct velocity, b dense acquisition, partial angular coverage and correct velocity, c dense acquisition, partial angular coverage and incorrect velocity, and d sparse acquisition, partial angular coverage and incorrect velocity.
Using the multi-echo spiral acquisition, whole-brain coverage with 1 mm isotropic resolution can be achieved within 2.5 min, shortening the scan time by a factor of 8.
However, with the VCT no land-cover change observations were included in 2009 due to limitations of image acquisition and cloud coverage, and therefore the simulations show no decrease in carbon emissions in 2009, despite the fact that the change observed in 2010 was equally distributed to 2009 and 2010.
Sagittal and axial localizer scans were used to select sagittal slices for echoplanar image acquisition, ensuring complete coverage of the head.
However, despite the decreasing costs of NGS technologies (Davey et al., 2011; Straub et al., 2012), financial constraints can still prevent the acquisition of higher-coverage WGS data or the use of multiple sequencing strategies.
Multi-slice acquisition (for improved spatial coverage) or multi-shot acquisition (for improved spatial resolution) would require multiple times the scan time above.
Northcoast would be a strategic acquisition due to its coverage of major markets like New York and Boston, says Baca, who believes that almost any large carrier could pick it up.
To take advantage of the high SNR available from hyperpolarization, we have applied compressed sensing to achieve a factor of 2 enhancement in spatial resolution without increasing acquisition time or decreasing coverage.
In addition, improved X-ray tube capacity and scan speed allow submillimeter acquisition of a large coverage without limitations.
