The #SantaBarbaraCounty Board of Supervisors took the first step of what promises to be a protracted and historic pivot to pull the plug on all onshore oil development anywhere in Santa Barbara County.
This Tuesday, the supervisors narrowly approved
— by a 3-2 vote —
⭐️a ban on any new onshore oil drilling.
The last time a new drilling proposal was approved took place in…

Abstract: Purpose In advanced computational MRI techniques, acquisition and reconstruction techniques are jointly designed. For reproducibility, it is therefore important to provide an open implementation of both. At the same time, any use in a clinical environment usually requires a close integration with the MRI scanner. Ensuring long-time reproducibility and maintenance then poses additional challenges. In this work, we aim to provide a fully integrated open-source framework that can meet these demands.
Methods A software framework to develop pulse sequences is added to the BART toolbox. In addition, a vendor-specific driver sequence is developed that can be used to run the sequence on a clinical MRI scanner enabling online adjustment of all relevant sequence parameters. Using the Pulseq format, the exact same sequence can also be reproduced offline. As proof-of-concept, quantitative MRI methods for T1 and joint water/fat R2*, B0 mapping using radial FLASH and model-based reconstruction are implemented in the proposed framework. Consistency between online and offline acquisition is validated in phantom and in vivo experiments.
Results Quantitative MRI methods consisting of acquisition and reconstruction were successfully implemented in BART. Acquisition parameters and FOV can be adapted online on a clinical MRI system. Quantitative parameter maps from model-based reconstruction agree for online and offline regenerated Pulseq acquisitions.
Conclusion This work enables reproducibility of advanced computational MRI methods within a comprehensive end-to-end open-source framework.

Sonnet 006 - VI
Then let not winter's ragged hand deface,
In thee thy summer, ere thou be distilled:
Make sweet some vial; treasure thou some place
With beauty's treasure ere it be self-killed.
That use is not forbidden usury,
Which happies those that pay the willing loan;
That's for thy self to breed another thee,
Or ten times happier, be it ten for one;
Ten times thy self were happier than thou art,
If ten of thine ten…
