Personal computer aided cerebral perfusion imaging with dynamic CT

摘要

Reports on the clinical implementation of dynamic computerised tomography (CT) perfusion imaging and quantitative measurement have increased dramatically of late. The advantages of dynamic CT perfusion imaging and quantitative measurement for the diagnosis of acute cerebral infarction have been acknowledged. However, most overseas CT vendors set perfusion imaging software package as an option for graphic workstation at a too high price for domestic practitioners. To foster the domestic implementation and development of this new technology, we have extended the earlier work. Applying the theory of central volume principle to DICOM 3. 0 standard forms of prime CT images, we developed dynamic CT perfusion imaging and quantitative measurement programmes for PCs using Visual C ++ in Windows 98 system.
