28 Jul 2005 | | Subject: | Tissues and Organs | q-bio.TO | | Affiliation: | Greifswald), Ralf Geske (Neubrandenburg), Michael Baake (Bielefeld | | Abstract: | The impulse response function (IRF) of a localized bolus in cerebral blood flow codes important information on the tissue type. It is indirectly accessible both from MR- and CT-imaging methods, at least in principle. In practice, however, noise and limited signal resolution render standard deconvolution techniques almost useless. Parametric signal descriptions look more promising, and it is the aim of this contribution to develop some improvements along this line. | | Source: | arXiv, q-bio.TO/0507042 | | Services: | Forum | Review | PDF | Favorites | |
