The black-box toolbox was developed by Esben Høgh-Rasmussen during a Ph.D. at the Neurobiology Research Unit, Copenhagen University Hospital, Denmark. It is used for research in inverse problems in PET and SPECT imaging of the brain.

The image of the bird used in the image deblurring examples, were shot by Germ Wind, and graciously donated under the terms of the GPL. See the examples for further information about the image.


The development of the toolbox would not be possible without the financial support from the following organizations:

Also, parts of the toolbox were developed at Tufts University, Massachussets, USA. This trip was made possible with funding from:
