A Based Bayesian Wavelet Thresholding Method to Enhance Nuclear Imaging
Enhance Nuclear Imaging Bayesian
<
2009/9/4
Nuclear images are very often used to study the functionality of some organs. Unfortunately, these images have bad contrast, a weak resolution, and present fluctuations due to the radioactivity disint...
Blind Deblurring Reconstruction Technique with Applications in PET Imaging
PET Imaging Blind Deblurring Reconstruction Technique
<
2009/9/4
We developed an empirical PET model taking into account system blurring and a blind iterative reconstruction scheme that estimates both the actual image and the point spread function of the system. Re...
