Image Registration and Communication Standards in Medical imaging
A major potential benefit in digital medical imaging is the possibility of extracting quantitative information, for example, of tissue character. However, there is an additional need to be able to register very different types of images, so as to be able to deduce physiological information within a precise anatomical identification. This is a 3-D problem, and after appropriate preprocessing, critical points can be established on diverse images such that they may be iteratively translated and rotated in 3-D. Results using a VAX linked to a Kontron image processor are encouraging. A more general problem is associated with defining communication standards so as to be able to transfer images from a variety of different medical imaging systems. A variety of standards have been proposed (AAPM, ACR/NEMA etc) and there is a requirement for an appropriate (international) data dictionary to be established to define the logical format, for which a proposal is presented.
