Magnetic Resonance Tomography

Magnetic Resonance Tomography or MRT is another name for Magnetic Resonance Imaging or MRI. The two terms refer to the exact same thing.

Magnetic resonance imaging is a type of medical imaging technology used to create 2D slide images of the human body, cut in cross section from any angle. The images are produced by the use of magnetic fields to align susceptible atoms in the body. This alignment is then manipulated to cause a pulsing effect that can be read by a magnetic sensor. Different body tissues pulsate at different frequencies, due to their atomic composition, creating the images.

Magnetic Resonance Sensor in a Sugar Cube of Space
The debut of a new type of magnetic resonance sensor for brainwaves and electrical activity - which changes the game totally for both fMRI and MEG. For the first time ever, portable, low-cost versions of both are actually a possibility.

Crossing the Blood-Brain Barrier for Improved Visualisation
When it comes to using chemical or radioactive markers to make parts of the brain easier to see, and more finely detailed with a magnetic resonance scan, your options have been rather limited.

Doubts raised over fMRI Validity
Doubts have been raised, over the accuracy of many fMRI (functional magnetic resonance imaging) studies, used to decode the information in the brain.

Specialized Brain Cells Predict Intentions as Well as Define Actions

Industry news, originally posted 23-02-2005. A study by UCLA neuroscientists featuring functional magnetic resonance imaging has for the first time found evidence that mirror neurons help people understand the intentions of others.

Brain Reading: fMRI
fMRI or functional magnetic resonance imaging, is one of the newest brain imaging technologies for the first decade of the 21st century. It is a basic form of Brain-Computer Interaction.

Brain Reading: Diffusion Spectrum Imaging
Diffusion spectrum imaging is a new technique at time of writing, which allows magnetic resonance brain imaging, at a much higher level of fidelity than fMRI permits.

Extra Sensory Perceptions: Sensing Magnetic Fields
The first known, successful implant of an extra sensory perception to detect magnetic fields the person with the new sense was near, occurred in 2005, when a small piece of neodymium, which is a rare earth metal, that forms a permanent magnet, was coated in a thin layer of silicon, and implanted into an emergency medical technician's finger.

Fast Adaptive Optics for 3D Medical Imaging
One of the greatest problems with tomography based medical scanners, is what happens when the patient moves (breathes, or pumps blood). The distortion that occurs in each slice has long been correctable, but takes a long time to correct. With near-instant correction now possible, real-time medical scanning is starting to look like a true possibility.

Dial H for Happiness: How Neuroengineering May Change Your Brain
A second part to Wired's article "Rewiring the Brain: Inside the New Science of Neuroengineering", continuing on along the same lines; looking at the work of Dr. Ed Boyden, and his prototype Transcranial Magnetic Stimulation machine.
