MR image data representation as NiftiImages

9

There is a fundamental issue in our approach of trying to convert MR data into the Nifti images objects. MR data have many different dimensions, obviously 3 spatial ones, but...

Gadgetron NUFFT producing a lot of output in stdout.

3

The non-uniform Fourier transform using Gadgetron generates a lot of output during the gridding. The output is just timing how long the gridding took. In the past this has caused...

CoilSensitivityData.fill() sets wrong coilmaps

2

Example for, 4 active channels, 10 repetitions, and a 320 by 320 pixel slice. Then having a coilmap object csm of type `sirf.Gadgetron.CoilSensitivityData` yields `csm.as_array().shape = (4,10,320,320)` If you have...

PET/MR Simulation Framework for Dynamic Data including Ground Truth information.

We should potentially move to a unit test framework for C++. Our current approach is to write a bunch of tests that check some functionality and then turn them into...

MR DICOM Writer casts float pixel values to integers

1

The DICOM writer stores the pixel values in the DICOMs as 16-bit unsigned integers. Any float value is seemingly cast to an integer. An SL Phantom written to DICOM will...
