Petrov explains it away for the team in the end but it is still astonishing.
They've developed a new MRI that has ten times better resolution than the best available. It should create lots of new brain science and be a much better tool in diagnostics. Will we be getting one for the new hospital?
'An intense international effort to improve the resolution of magnetic resonance imaging (MRI) for studying the human brain has culminated in an ultra-high resolution 7 Tesla scanner that records up to 10 times more detail than current 7T scanners and over 50 times more detail than current 3T scanners, the mainstay of most hospitals.
The dramatically improved resolution means that scientists can see functional MRI (fMRI) features 0.4 millimeters across, compared to the 2 or 3 millimeters typical of today’s standard 3T fMRIs.
...
Incorporating newly developed hardware technology from those groups, Siemens collaborated with Feinberg’s team to rebuild a conventional 7 Tesla MRI scanner delivered to UC Berkeley in 2000 to improve the spatial resolution in pictures captured during brain scans.
...
To reach higher spatial resolution, the NexGen 7T scanner had to be designed with a greatly improved gradient coil and with larger receiver array coils — which detect the brain signals — using from 64 to 128 channels to achieve a higher signal-to-noise ratio (SNR) in the cortex and faster data acquisition. All these improvements were combined with a higher signal from the ultra-high field 7T magnet to achieve cumulative gains in the scanner performance.
...
The most common MRI scanners employ superconducting magnets that produce a steady magnetic field of 3 Tesla — 90,000 times stronger than Earth’s magnetic field.
“A 3T fMRI scanner can resolve spatial details with a resolution of about 2 to 3 mm. The cortical circuits that underpin thought and behavior are about 0.5 mm across, so standard research scanners cannot resolve these important structures,” Gallant said.
...
For the moment, NexGen 7T brain scanners must be custom-built from regular 7T scanners. The cost should be considerably lower than the $22 million required to build the first one, however.'

You really can't follow a simple dialogue, can you
