Hyperspectral Images often suffer from missing pixels due to acquisition system problem. Missing pixels in images are usually tackled by means of interpolation methods by using neighborhood known pixels, but once the missing region is large, there may not be sufficient information in the neighborhood to reconstruct well. Fortunately, hyperspectral sensors are also often flown with boresighted, higher...
Image reconstruction plays an important role in medical imaging technology, the quality of reconstructed image will directly affect the results of clinical diagnosis. How to assess the quality of the image is an attractive research topic. In this paper, a comparative study of quality assessment for medical image with seven common algorithms was presented, the images were reconstructed from the result...
The approach of simulation plays an essential role in the research of PET/CT imaging technology. In this paper, a simulation study of the GE ST PET/CT acquisition implemented by GATE (Geant4 Application Tomography Emission) software packages was presented. GATE provides abundant of functions to simulate both SPECT/PET imaging procedure and phantom generation. The simulation experiment based on the...
