High-Speed Fluorescence Imaging and Intensity Profiling of Femtosecond-Induced Calcium Transients
Imaging Calcium Transients
2009/9/8
We have demonstrated a combined imaging system, where the physiology of biological specimens can be imaged and profiled at 10–20 frames per second whilst undergoing femtosecond laser irradiation. Indi...
Intensity inhomogeneity (IIH) is often encountered in MR imaging, and a number of techniques have been devised to correct this artifact. This paper attempts to review some of the recent developments i...
Registration of Brain MRI/PET Images Based on Adaptive Combination of Intensity and Gradient Field Mutual Information
MRI/PET Images Intensity
2009/9/7
Traditional mutual information (MI) function aligns two multimodality images with intensity information, lacking spatial information, so that it usually presents many local maxima that can lead to ina...
An Efficient Estimation Method for Reducing the Axial Intensity Drop in Circular Cone-Beam CT
Estimation Method Circular Cone-Beam CT
2009/9/4
Reconstruction algorithms for circular cone-beam (CB) scans have been extensively studied in the literature. Since insufficient data are measured, an exact reconstruction is impossible for such a geom...
