emboli differentiation - the new module for QL software
The emboli differentiation software module is unique: It is the only clinically proven TCD software to discriminate between gaseous and solid emboli. Physics teaches us that with gaseous emboli the amplitude of the reflection depends strongly on the insonating frequency. With solid emboli, the reflection amplitude is almost constant.
The emboli differentiation software takes advantage of this phenomenon and is able to simultaneously process two different insonating frequencies 2 and 2.5 MHz by using special developed and patented 2+2.5 MHz multi-frequency probes.
Utilizing this technique, in combination with the digital Multi-Gating technique and a series of sophisticated algorithms, emboli can thus be detected and classified as either gaseous or solid due to the different reflection at 2 MHz and 2.5 MHz.
The emboli differentiation software uses a unique graphical display to present the acquired date. The graph shows the number of gaseous and solid emboli as well as the number of artefacts, and the intensity ratio of each signal. The audio and spectral signals are stored continuously. This enables easy re-analysis of the data in offline mode. The intuitive playback panel allows the data to be easily managed.
Successful applicable in the different fields of stroke care, stroke prevention and surgical neuro protection for example
to correlate stroke and transient ischemic attack risk
