Partial volume correction (PVC) can compensate for cross-talk between different anatomical regions in images from a functional imaging system with poor spatial resolution, such as PET or SPECT, by utilizing data from a high-resolution structural imaging modality, such as CT or MRI. We have developed a new PVC method for SPECT, and here we present an evaluation of this method using clinical data from...
We have developed a visual-tracking-system (VTS) which uses stereo-imaging to track the motion of markers on patients during cardiac SPECT imaging with the goal of using the tracked motion to correct for patient motion. The aim of this study is to determine using MRI in volunteers if the rigid-body-motion (RBM) model can be used to predict the motion of the heart within the chest from the motion of...
This paper dealt with the following topics: image segmentation; computer-aided diagnostics; MRI; image reconstruction; strain imaging; image processing algorithms; electron microscopy for biomedical and biological applications; image denoising and enhancement; image classification; image registration; large-scale physiological modeling and simulations initiatives; PET; SPECT; DTI; FMRI; image restoration;...
Vision information processing (VIP) is the important supports of image processing. Currently, VIP has become as a leader direction in remote sense image processing (which mostly serves the government and military) and in medical Image processing (which widely serves a great numbers of patients). Medical imaging and medical image analysis techniques are the hotspots of the biomedical engineering. On...
The following topics were dealt with: diffusion tensor imaging; cardiac and vascular imaging; atlases and nonrigid image registration; ultrasound imaging and restoration; MEG and EEG imaging; computer vision for systems biology; PET and SPECT image reconstruction; image segmentation and shape analysis; image guided diagnosis, surgery and therapy; diffusion tractography; cellular and molecular image...
