Abstract
The purpose of neuroimaging in stroke diagnosis is to visualize early phases of brain ischemia evolution. Different forms of computerized support are often affected by the presence of many false over-interpretation areas, thus it is of great interest to provide neurologically verified regions in order to improve the accuracy of ischemia assessment. We propose Stroke Bricks (StBr) as an arbitrary spatial division of brain into the block of tissues associated with specific clinical symptoms of ischemic stroke. Neurological stroke deficits are translated into respective areas of possible ischemia on the basis of arbitrarily proposed symptoms-regions mapping rules. StBr concept may be useful for an integrated radiological CT-based assessment of suspected stroke cases or can be included into computer-aided tools to optimize the evaluation of stroke site and its extent.
The accuracy of StBr was presented on the basis of experimental simulation with real clinical data.

The National Institutes of Health Stroke Scale (NIHSS) is a systematic assessment tool that provides a quantitative measure of stroke-related neurological deficit.
