Functional studies (fMRI), interventional Cardiovascular Magnetic Resonance Imaging (iCMR) & Patient Entertainment
OptoStim® – a special monitor for usage inside the MRI cabin. The “one for all”-solution: multifunctional (fMRI, iCMR and patient entertainment) and for any size of MRI cabins!
Resolution & size
OptoStim® is 32“ in size and has a UHD (”4K”) resolution of 3840 x 2160 pixels at 139 PPI and 60 Hz (optionally with 120 Hz!). The contrast ratio is 2000:1, the brightness is 400 cd/m², and the response time is only 5 ms. Despite its size, it fits perfectly into even the smallest MR booth, so that the entire image area is still visible. With its stand, it can be freely positioned to the magnet and adjusted to any height.
fMRI + iCMR
+ Patient entertainment = 1 Price
Developed for neurological studies on behalf of the Max Planck Institute, OptoStim® can be used in all areas of functional studies (fMRI), as well as for iCMR or patient entertainment. You receive a versatile, latest-generation monitor that offers maximum flexibility.
Modular & expandable
Thanks to its versatile interfaces, OptoStim® is an open and expandable system that can be controlled in a variety of ways. It is open to expansions,
e.g., with MotionDetect or EyeTracking. We supply it with a remote control that allows you to create a true mirror/flip image for use with your mirrored glasses. We can also offer you optimal headphones for patients and fMRI response devices.

Quality Made in Germany
medres attaches great importance to regional manufacturing, including for supplier parts. We provide you with products that truly deserve the label “Made in Germany.” The quality of our products reflects this perfectly. For example, OptoStim® has been used successfully for over 10 years at the DZNE (7T, 3T) and the DLR (PET-MR (Siemens Biograph mMR)). Other companies cannot offer these values – and try getting a fast service there!
In addition, OptoStim® can be supplemented with modular components, e.g., MotionDetect, EyeTracking, a wide range of headphones, patient response devices, and much more.
OptoStim® is used by leading institutions (across Europe). Why? Because there is no better system out there – let the data convince you. As a manufacturer, we are always there for our customers and don’t just sell our products, we also provide support – even after a purchase! We don’t cause any export problems and are extremely fast – try us out! We are highly flexible, even offering a hire purchase option – whatever suits your finances!
OptoStim® is used by leading institutions including:
Charité, German Aerospace Center – DLR, German Ceter for Heart Insufficiencies, MDC Berlin, German Center for Neurodegenerative Diseases, Heart Center Leipzig, University Hospital Bonn, Max-Planck-Institute Munich, MPI Cologne and MPI Göttingen, University Hospital Luxembourg, University Hospital of Maastricht UMC+, and much more!
Of course, you can also use OptoStim® to entertain your patients. From an economic perspective, this is advantageous because MRI sequences do not usually need to be repeated for calm patients. Our system therefore also helps to reduce the examination costs of radiological facilities.
