Coil array with field monitoring and image reconstruction
The NeuroCam is a brain coil array with fully integrated field monitoring capabilities, providing a user-friendly solution that does not impede the standard imaging workflow. By concurrently measuring the field dynamics, one can correct for systematic and physiologic artifacts and thus achieve more accurate and consistent imaging.
It is paired with receiver coils that were specifically designed for high-signal-to-noise ratio and parallel imaging performance in the brain. The combination enables a focus on advanced MR application research and move towards more reliable neuroscience and diagnosis.
- Acquire robust and consistent data for advanced MR applications
- Obtain exceptional SNR and parallel imaging acceleration
- Perform diffusion imaging and fMRI with significantly increased resolution and accuracy
Plug-and-play concurrent magnetic field monitoring
Fast and quantitative MRI methods are commonly limited by inaccurate or unstable image encoding. These limitations can be elegantly avoided by using the actual encoding for image reconstruction. The NeuroCam provides an integrated solution for acquiring the image encoding. Together with the skope-i image reconstruction software, it provides all of the benefits of cutting-edge field monitoring and push-button image reconstruction. The combination enables a focus on ground-breaking research and a move towards more reliable diagnosis.
Excellent SNR and parallel imaging performance
A challenging requirement from MR imaging is increasing SNR while shortening acquisition time. The NeuroCam‘s integrated MR receiver array was specifically designed to provide researchers with optimum SNR and parallel imaging performance in specialized imaging of the whole brain. Because the NeuroCam also includes an integrated field monitoring array, it delivers a considerable increase in quality and resolution of single-shot images. This enables the elucidation of small pathologies and performing of advanced research.
Unprecedented fMRI and diffusion imaging performance
Diffusion MRI and fMRI are commonly limited by image artifacts and low SNR. In DWI, the NeuroCam removes image distortions, and the coil‘s intrinsic high SNR can be further boosted by using spiral readouts enabled by field monitoring. Thereby, the NeuroCam can deliver highest spatial resolution images and most accurate quantification results. In fMRI, high parallel imaging acceleration reduces artifacts and increases the temporal resolution. Moreover, spiral acquisitions widen the horizons for fMRI investigations by the possibility to combine outside-in and inside-out variants and fully flexible TE to control signal dropout.

Camera Acquisition System
The field sensor signals of the NeuroCam are acquired by the 16-channel Skope Camera Acquisition System and automatically processed to provide the actual magnetic field dynamics. The field dynamics can be conveniently displayed in the user interface or piped directly into the skope-i, image production software.

The image production software complements the NeuroCam and takes into account
- Measured/simulated gradient encoding
- Coil sensitivity information (SENSE)
- Static B0 maps
- Higher order field evolution
Parallel imaging performance
The NeuroCam is developed for fast and robust neuroimaging by advanced radiofrequency design with low SNR penalty for accelerated Cartesian and spiral imaging (see image below).
