First transcranial Doppler Holter
Atys, manufacturer of Doppler devices for more than 25 years, collaborated with Dr. Rune Aaslid to develop the first Transcranial Holter.
The TCD-X offers new opportunities for recording Doppler signals for several hours on ambulatory patients involved in sports or daily life activities.
TCD-X is commonly used for the detection of emboli in patients with asymptomatic carotid stenosis.
Easier Doppler signal search
The Doppler probe is robotized.
It automatically scans all its possible orientations in search of the Doppler signal.
It is positioned itself on the best signal.
The Doppler probe can automatically adjust its orientation during recording to ensure stability of signal quality over time.
The probability of losing the signal is reduced.
New opportunities for brain perfusion studies
Thanks to its unique characteristics, the TCD-X is a powerful tool that offers new perspectives for emboli detection and physiological studies.
The system that maintains the probe on the patient's head is very comfortable.
It is much more comfortable than traditional headframes that induce pain less than 30 minutes after placement.
It looks like a spectacle frame. The patients withstand it very well for several hours.
This is an important feature for emboli detection: the probability of recording emboli is proportional to the duration of the recording.
The recording time can be programmed. The recording stops properly without the help of a trained operator.
The software for reading and analyzing the Doppler signal makes it possible to quickly display:
- The results of the detection of emboli
- Velocity profiles and their trends
Also, for the sake of efficiency, the emboli detection software facilitates the control of HITS by the expert.
- It ranks HITS based on a confidence factor.
- It displays the HITS list as well as detailed information characterizing them.
- It replays each HITS (video signal and audiogram)
An examination report can be automatically generated and exported.
