  • Fully Automated Software for Polar-Map Registration and Sampling from PET Images

    Publication Year: 2006, Page(s):3185 - 3188
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (374 KB) | HTML iconHTML

    Left ventricle myocardial activity (LV) from volumetric images is commonly presented in a 2D format called a polar map. Few applications offer complete automation of the registration and sampling process, which may lead to biasing of the results by the user and increased variability. A fully automated process is described which includes two steps: reorientation of the data to a common LV reference... View full abstract»

  • A method for automatic extraction of striatal structures for dose-finding studies in PET

    Publication Year: 2006, Page(s):3189 - 3194
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (449 KB) | HTML iconHTML

    The extraction of regions of interest (ROIs) from positron emission tomography (PET) neuroreceptor studies enables the computation of regional binding potential (BP) value of the radioligand in a specific brain structure. When a subject is scanned during baseline (no medication) and intervention (medication) we can compute the receptor occupancy value (a function of BP values). This is important i...

  • Efficient Model of the Collimator Blurring in Pinhole SPECT

    Publication Year: 2006, Page(s):3195 - 3199
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4057 KB) | HTML iconHTML

    We propose a new method for collimator blurring correction in pinhole SPECT, that uses the spherical symmetry of the blob basis functions. We study its performance and compare with the other correction methods, namely multi-ray methods. We also investigate some limitations of the multi-ray methods. View full abstract»

  • Comparison of Image Segmentation and Registration Based Methods for Analysis of Misaligned Dynamic H152O Cardiac PET Images

    Publication Year: 2006, Page(s):3200 - 3204
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (152 KB) | HTML iconHTML

    In this study, we compared quantitatively image segmentation and registration based methods to find misalignment between two dynamic H2 15O cardiac PET images. Due to a low contrast between tissues in oxygen-15-labeled images, we first applied independent component analysis (ICA) to separate the different cardiac structures. The misalignment was then defined from the separate... View full abstract»

  • A Template Based Approach for Automatic Seed Detection in Post-implant CT Images for Prostate Brachytherapy

    3D reconstruction of implanted seeds is an essential step for post-operative dosimetry in prostate brachytherapy. However, because of the slice thickness and artifacts produced by seeds, large areas will be appeared in computed tomography (CT) images representing many seeds. We propose a new algorithm for the automatic localization and reconstruction of implanted seeds with main focus on localizin... View full abstract»

  • Multi-modal and Multi-temporal Image Registration in the Presence of Gross Outliers Using Feature Voxel-Weighted Normalized Mutual Information

    Cited by:  Papers (3)

    A novel automatic registration algorithm based on new similarity measure called Feature Voxel-Weighted Normalized Mutual Information (FVW-NMI) is presented for accurate and robust multi-modal and multi-temporal image registration in the presence of gross outliers. Based on assumption of corresponding voxels having some common similar spatial information between multi-modal and multi-temporal image... View full abstract»

  • A Fast Method for Kinetic Parameter Estimation

    Publication Year: 2006, Page(s):3213 - 3216
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (120 KB) | HTML iconHTML

    Kinetic parameter estimation using PET is an important tool for in vivo quantification of physiological parameters in humans and animals. Iterative methods based on nonlinear weighted least squares criterion have been widely used to estimate kinetic parameters. Most of these methods do not guarantee to converge to the global optimum because the cost function is nonconvex and there may exist multip... View full abstract»

  • Wavelet Denoising of Dynamic PET Data: Application to the Parametric Imaging of Peripheral Benzodiazepine Receptor

    Publication Year: 2006, Page(s):3217 - 3220
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4376 KB) | HTML iconHTML

    Low signal-to-noise ratio (SNR) of time activity curve (TAC) at the voxel level causes severe bias and poor precision for estimated binding potential (BP) in peripheral benzodiazepine receptor (PBR) using nonlinear least square (NLS) fitting. The purpose of this study is to evaluate noise reduction capability of wavelet denoising for estimated BP image. We applied spatial (3D) wavelet denoising to... View full abstract»
