The CT scan was introduced in the 1970s and quickly became one of the most widely used methods of imaging. A CT scan can be performed in under a second and produce rapid results for clinicians, with its ease of use leading to an increase in CT scans performed in the United States from 3 million in 1980 to 62 million in 2007.
This method uses the multiple transmit coils from parallel imaging systems to reduce and better mitigate the RF power deposition by relying on shorter RF pulses. One advantage of using parallel excitation with coils is the potential to reduce scan time by combining the multiple short RF pulses and the parallel imaging capabilities to cut scan time.
The first study of the human brain at 3.0 T was published in 1994, [13] and in 1998 at 8 T. [14] Studies of the human brain have been performed at 9.4 T (2006) [15] and up to 10.5 T (2019). [16] Paul Lauterbur and Sir Peter Mansfield were awarded the 2003 Nobel Prize in Physiology or Medicine for their discoveries concerning MRI.
Later, when the subjects were shown new images in the fMRI, the system detected the patient’s brain waves, generated a shorthand description of what it thinks those brain waves corresponded to ...
The script for Brainscan had initially been written in 1987 by Andrew Kevin Walker and originally was centered around a VHS tape, however after producer Michael Roy acquired the script he performed some uncredited re-writes turning the tape into an interactive CD-ROM video game in order to tap into the public fascination with virtual reality.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body.
The research relied on brain scans of the patients. A quarter of hospital patients who are unresponsive and don’t physically respond to commands may be doing so mentally, a new study found. ...
The scan tests for consistent and sufficient blood flow to all areas of the brain by having patients breathe in xenon gas, a contrast agent, to show the areas of high and low blood flow. Although many trial scans and tests were ran during the development process of computed tomography, British biomedical engineer Godfrey Hounsfield is the ...
