Providing high quality MR images for all patient groups
with smart-sync

smart-sync is a MR compatible Doppler ultrasound system, which synchronizes the cardiac cycle with the MR image acquisition (“Gating”). It provides a reliable and undisturbed gating signal independent from the used field strength. 

smart-sync unlocks for the first time fetal cardiac gating for clinical routine enabling high quality cardiac imaging with anatomical and functional information.

At the same time, smart-sync can be used for all other cardiac MR scans and patient groups that require cardiac gating such as paediatric and adult cardiovascular MR imaging.



The Sensor Box is the core of smart-sync and can be used for 1.5T and 3T. The cardiovascular motion is detected using Doppler ultrasound and translated into a gating signal. Taking advantage of the Doppler effect, the Sensor Box detects any kind of cardiac motion. The area of application is defined by the kind of ultrasound transducer.

If adult cardiac gating is desired, the adult transducer is used. If you want to perform fetal cardiac gating, the fetal transducer is used. 
The Sensor Box is wirelessly connected to a specially designed Connector Box to enable an
easy wireless integration into every MR System of all vendors.



To verify easily a correct signal and gating for improving the workflow, the Sensor Box is equipped with a Display on top of it.
On the Display the waveform is shown to ensure the correct detecting of the heartbeat. The trigger is also shown exactly at the moment where the trigger is sent wirelessly to the MRI. The Display also shows the wireless connection status.



The Connector Box enables the connection to any MR System with smart-sync. The Sensor Box transmits all necessary information to the Connector box.

The Connector Box is specifically designed to match the needs of every MR System to integrate smart-sync in an easy and effective way.



Finding the heart of a fetus can be challenging but time is limited in clinical routine. To enable an effective and proven method to locate the fetal heart we have developed a special MR compatible headphone to listen to the audio signal of the beating heart.

Using the headphones for fast and correct localization of the fetal heart ensures an easy workflow for every user.



smart-sync is battery powered and wireless. The Charging Station ensures a reliable storage place for the Sensor Box and the ultrasound transducer. It also functions as your on/off button.

Once you remove the Sensor Box from the Charging Station it automatically connects to the Connector Box and you can start the application.



The selection of the ultrasound transducer defines the application for the fetal case or for the adult case:

specifically designed for the demanding challenge of a reliable fetal heartbeat detection

specifically designed for an easy and fast placement to detect the adult heartbeat 



The cable is specifically developed for MR compatibility and  interference-resistance.

The cable is not disturbed by the high magnetic field and connects the ultrasound transducer with the Sensor Box.
