The development and manufacture of DWL Transcranial Doppler Sonography (TCD) is the core competence of Compumedics Germany.
DWL USA, Inc., located in Cameron Park, California, with US wide local sales representation, provides DWL products, support and services to North American customers. Transcranial Doppler Sonography (TCD) has its unique performance in measuring and analyzing flow velocity in blood vessels and detecting cerebral micro emboli. In close cooperation with scholars and research institutes throughout the world, DWL has been perfecting diagnostic methods, developing new applications, and creating Doppler systems, which combine cutting edge performance with unmatched ease of use. With each new DWL system generation, the Doppler Sonography becomes more flexible and user-friendly, and its reports of diagnostic findings become more precise and meaningful.
Here you’ll find the latest articles on TCD applications, diagnostics, and treatment methods, all based on clinical research and publications.
Once considered optional, Transcranial Doppler (TCD) has become a key diagnostic tool in evaluating right-to-left shunts in cryptogenic stroke. This article summarizes how major neurological and […]
In a recent case report, transcranial Doppler sonography detected bilateral cerebral air emboli during cardiac surgery—while EEG and NIRS remained unchanged. Early detection through TCD, combined […]
A new method transforms transcranial Doppler (TCD) velocity signals into cerebral arterial blood volume (CaBV) waves, revealing how impaired intracranial compliance affects blood distribution within […]
