  • Tomography
  • SPECT/CT combines high resolution anatomical 3D computerized tomography (CT) and single photon emission computerized tomography (SPECT) as functional imaging, which provides 3D information about biological processes into a single imaging modality.Furthermore, most analyses are done in 2D, although rich 3D data are available.Our method is based on 3D localisation using clinically relevant anatomical landmarks and frames of reference, along with intensity value normalisation using clinically relevant reference regions.

  • invariance
  • Here, we used an functional magnetic resonance-adaptation paradigm to investigate image invariance in face-selective regions of the human brain. (nih.gov)
  • However, contrary to the predictions of models of face processing, comparable levels of image invariance were evident for both familiar and unfamiliar faces. (nih.gov)
  • To determine image invariance in face-selective regions, the images from Experiment 1 were incorporated into a block design fMR-adaptation paradigm. (nih.gov)
  • quantification
  • SlideToolkit: an assistive toolset for the histological quantification of whole slide images. (nih.gov)
  • CONCLUSION: Rescan agreement was excellent for reduced-dose image acquisition with iterative reconstruction and standard-dose acquisition with filtered back projection for the quantification of coronary calcium by CT. (gwu.edu)
  • patients
  • In order to verify the process, a set of images from prescription drug abusers and patients with migraine have been used. (mendeley.com)
  • Evaluation of Right Ventricular Function by Using Tissue Doppler Imaging in Patients after Repair of. (biomedsearch.com)
  • In addition, anatomical magnetic resonance images were collected for all patients and a subsample of the controls (n=21) after task completion. (curehunter.com)
  • tissue
  • Here, we develop and validate a noninvasive method to measure pulmonary artery (PA) compliance using ultrasound color M-mode (CMM) Doppler tissue imaging (DTI). (biomedsearch.com)
  • Ultra-fast processing of gigapixel Tissue MicroArray images using high performance computing. (nextbio.com)
  • In the fourth step (analysis), tissue is analyzed and results are stored in a data set.Using this method, two consecutive measurements of 303 slides showed an intraclass correlation of 0.99.In conclusion, slideToolkit provides a free, powerful and versatile collection of tools for automated feature analysis of whole slide images to create reproducible and meaningful phenotypic data sets.

  • recognition
  • Image category recognition is important to access visual information on the level of objects and scene types. (biomedsearch.com)
  • Because many different descriptors exist, a structured overview is required of color invariant descriptors in the context of image category recognition. (biomedsearch.com)
  • Image-invariant responses in face-selective regions do not explain the perceptual advantage for familiar face recognition. (nih.gov)
  • It is widely believed that this difference in perception and recognition is based on the neural representation for familiar faces being less sensitive to changes in the image than it is for unfamiliar faces. (nih.gov)
  • Fourier
  • Fourier undersampling is also customized to better accommodate each reconstruction method: random undersampling for compressed sensing and regular undersampling for parallel imaging. (biomedsearch.com)
  • whereas
  • To better exploit wavelet-domain sparsity, compressed sensing can be used for high-spatial-frequency regions, whereas parallel imaging can be used for low-spatial-frequency regions. (biomedsearch.com)
  • In Experiment 2, the images in each block were from the same identity, whereas, in Experiment 3, the images were from different identities. (nih.gov)
  • Examples
  • RESULTS: Examples using the proposed method demonstrate successful reconstruction of both low-spatial-frequency content and fine structures in high-resolution three-dimensional breast imaging with a net acceleration of 11-12. (biomedsearch.com)
  • c) Examples of the 2-image condition in Experiment 2 (left) and Experiment 3 (right). (nih.gov)
  • Slides
  • Relatively few free toolkits are, however, available for fully digitized microscopic slides, usually known as whole slides images. (nih.gov)
  • Volume
  • Virtual organ computer-aided analysis (VOCAL) was used to calculate volume of gestation sac (GSV) and yolk sac (YSV) and SonoAVC (sonography-based automated volume count) was used to quantify fluid volume (FV). (biomedsearch.com)
  • studies
  • Our goal is to facilitate a standardised approach to quantitative data collection and comparison of clinical studies using SPECT/CT, enabling more widespread clinical use of this powerful imaging tool. (nih.gov)
  • CONCLUSION
  • In conclusion, slideToolkit provides a free, powerful and versatile collection of tools for automated feature analysis of whole slide images to create reproducible and meaningful phenotypic data sets. (nih.gov)
  • machine
  • Graph theory is also widely used as a representational form and characterization of brain connectivity network, as is machine learning for classifying groups depending on the features extracted from images. (mendeley.com)
  • similar image
  • The ability to recognize familiar faces across different viewing conditions contrasts with the inherent difficulty in the perception of unfamiliar faces across similar image manipulations. (nih.gov)

  • regions
  • We found clear evidence for a degree of image-invariant adaptation to facial identity in face-selective regions, such as the fusiform face area. (nih.gov)
  • This suggests that the marked differences in the perception of familiar and unfamiliar faces may not depend on differences in the way multiple images are represented in core face-selective regions of the human brain. (nih.gov)
  • color
  • In addition, the distinctiveness of color descriptors is assessed experimentally using two benchmarks, one from the image domain and one from the video domain. (biomedsearch.com)
