    The authors have developed four applications where registration of images from different modalities provides opportunities for synergism. By combining NR and SPECT images of the brain, it is possible to locate functional abnormalities indicated by SPECT with respect to the anatomy imaged by MR. This may provide opportunities for more precise surgery of functional lesions which are not visible in M... View full abstract»

    Acquiring and displaying 3D (volume) sets of ultrasound (US) data raises a number of interesting questions of both principle and practice. Some of these relate quite widely to soft tissue imaging in general, others such as the problem of what to do about `speckle', are more specific to US. The practical problems are such that US has lagged very far behind techniques such as CT and MRI in establish... View full abstract»

  • Wide-angle acquisition and volumetric reconstruction in position emission tomography the goal, the problems and implementation

    Publication Year: 1991, Page(s):311 - 313

    A method of acquiring wide angle PET data has been described, the practical reasons for this development have been outlined. The ensuing problems associated with this have been addressed, and techniques are being developed to correct for them. The results generated from the preliminary studies suggest that the wide angle data acquisition is an acceptable approach to increase camera sensitivity, an... View full abstract»

    The complementary nature of single photon emission tomography (SPECT) and transmission computed tomography (CT) is demonstrated in two clinical applications: (i) dosimetry of targetted radiotherapy and (ii) determination of the pulmonary distribution of drug administered as aerosol by metered dose inhaler. In order to perform multi-modality image analysis it is necessary to be able to transfer the... View full abstract»

    The authors describe part of the work of the IED research project MIRIAD, `Medical Image Reconstruction Interpretation Display', The project as a whole has a strong interest in volume imaging. The problems being addressed include those inherent in human interaction with these large datasets (presentation, control interface) and also the goal of true multi-modal image interpretation, combining the ...

  • 3D graphics in surgical simulation

    Publication Year: 1991, Page(s):211 - 213

    The author discusses the development of an integrated system for the planning of maxillo-facial and cranial surgery. The system makes use of computer graphics to simulate surgical operations on the bone and produces a prediction of the effect of the surgery on the soft tissue and appearance of the face. The data required consists of a suitable set of contiguous X-ray CT slices which may be used in... View full abstract»

  • Interactive three-dimensional and dynamic display of gated blood pool tomograms

    Publication Year: 1991, Page(s):7/1 - 7/4

    The complete system described provides a powerful adjunct to the existing computing and display facilities associated with the section scanner. It provides a means by which a large amount of three dimensional and temporal data can be displayed in a single image, but also provides for user interaction with such images to allow the data to be viewed from different positions and also to allow for rem...
