SFB test data platform

Here you can find a selection of benchmark problems for image reconstruction and image processing tasks from different application areas of the SFB. These can be used for validating the algorithms in your SFB publications. New data sets, particularly from still missing applications, are welcome. We are also hoping to showcase the most successful reconstruction(s) for each data set.

MRI test images

  1. T1 weighted GRE scan of a multiple sclerosis patient

    Note: No pronounced MS lesions are visible with this contrast and in this slice

    (Florian Knoll, 02.02.2011)

    1_brain_T1
  2. T2 weighted TSE scan of a healthy volunteer

    (Florian Knoll, 02.02.2011)

    2_brain_T2
  3. RF-spoiled radial FLASH sequence without cardiac gating and during free breathing

    (Florian Knoll, 02.02.2011)

  4. SE measurement of the knee of a healthy volunteer

    (Florian Knoll, 02.02.2011)

    4_knee
  5. 3D FLASH Contrast enhanced scan of the carotid arteries

    3D image stack of 40 slices

    (Florian Knoll, 02.02.2011)

MRI raw data

  1. T2 weighted TSE scan of a healthy volunteer (4 channel head coil)

    (Florian Knoll, 02.02.2011)

    2_brain_T2
  2. T2 weighted TSE scan of a healthy volunteer (32 channel head coil)

    (Florian Knoll, 02.02.2011)

    2_rawdata_brainT2_32c
  3. SE measurement of the knee of a healthy volunteer (8 channel coil)

    (Florian Knoll, 02.02.2011)

    4_knee
  4. RF-spoiled radial FLASH sequence without cardiac gating and during free breathing

    32 channel body array coil, compressed to 12 virtual channels using svd based coil compression

    Note: This data set was acquired with a radial acquisition. The corresponding k-space trajectory is also included ('k', 256x125 matrix). The non-uniform FFT from Jeff Fessler's Image Reconstruction Toolbox is needed for reconstruction of this data set.
