In a recent research conducted at the ATR Computational Neuroscience Laboratories in Kyoto, Japan, functional magnetic resonance imaging (fMRI) and Electroencephalography (EEG) systems were used to decipher dream images during the hypnagogic sleep stage; the stage experienced during the transition to and from sleep. The experiment focused on three subjects who were asked to fall asleep [...]

Current developments in multimodal imaging are stemming from the merging of two imaging devices into one, thereby combining the benefits that each device has to offer. One such example is a hybrid created from the combination of an Magnetoencephalography (MEG) with Magnetic Resonance Imaging (MRI). The results are showing that sometimes one and one are [...]
On November 1, 1991, the first paper on functional MRI (fMRI) was published in the journal, Science. Since then, fMRI has helped to develop a surge of interest in cognitive neuroscience. Many world-class research centers are dedicated to using fMRI as the main tool of investigation. fMRI has not only focused on cognitive research but [...]
Just as digital technologies have dramatically improved home audio and video fidelity, flat panel digital X-ray technology offers significant improvement in image quality and dose utilization. The performance of the flat panel detector imagers is rated as the value of DQE (Detective Quantum Efficiency).
How is MRI Parallel Imaging Used? MRI parallel imaging utilizes the multiple elements of phased array coil system. Each element of the coil system is associated with a dedicated radio frequency channel (a special single-channel radio receiver) whose output is processed and combined with the outputs of the other channels (signals acquired by the other [...]
How Advanced Technologies Improve MRI Imaging Multichannel radiofrequency and parallel imaging technologies are hardware and software implementations, respectively, aimed at improving the coverage, signal resolution and speed of MRI examinations. With multichannel RF technology, the MRI signal used to form an image is collected by an array of separate detectors, or coil elements. Each element [...]
Before purchasing an MRI system, it is important to take into consideration the following main technical points, in order to make the best decisions possible for your medical facility: The MRI system should be FDA-approved The MRI system should comply with the IEC 60601-2-23 standard The MRI system should comply with all Dicom 3.0 mri [...]
