anyways. i think it is pretty much good to say that the results show .044 hz / mm / tick as the steady answer within reason....
collect scan data for a bunch of gradient strengths, and then plot the relationship of scaling factor of gradient tick to slope / gradient strength for each direction. use a large phantom to do this, maybe the big box phantom to do this.
this is dependent on the following tasks:
2 because this will make it much easier to script this in a jupyter notebook and generate the plots easily after that fact
This is a precursor to the following task:
8 This needs to be done before we can eliminate the need to pre-record gradients in the calibration sequence.
End result of this ticket should be a solid answer that shows the conversion from tick mark to gradient field strength for each of the linear gradients. this should then allow me to complete #8.
