Great video but it has two minor errors that might throw people off. @7:30 The transverse vector decays much more quickly than the longitudinal vector is restored and so the transverse vector decay is effectively independent of the longitudinal relaxation. @8:22 To convert from the k-space (frequency domain) to the spatial domain you take the inverse Fourier transform, not the Fourier transform. Keep up the good work :)

I took a 4th year physics course that discussed how MRI works. I was surprised how complicated it really is. Even K-Space is complicated, you could take a 16 week course on just K-Space.

maybe if you're very low IQ? K space is just spatial frequency space. It just so happens it's the domain in which the signal is sampled. How is that complicated?

Where you wrote Fourier Transform it’s actually where you perform an inverse Fourier Transform, as you first Fourier Transform the digital signal (and you are in k-space), and then you do an inverse FT of the digitalised signal in order to visualise the image

As a safety measures for people fear death, do not scan the brain and had the brain outside of the scan area then design so that the synchronized field top down or bottom up and spin around as the recorder of the response of body then in case of burial start the shape of the wave in sine wave and shooting emission of beta at same result in side way in to extract energy and matter small amount at a time until entire body convert into energy light. In the MRI used as treatment and diagnostic is the same first part is matching natural body internal energy motion then slowly down and recorded emit energy then speed up and recorded response and detect anomaly in responded reaction to indicate the illnesses and focus on adjust it back to normal until all response according to organ functional standard of most normal healthiest state that recorded on file for each person under 30 years old and this is forever life is achieved

Why would spin orientate antiparallel to B0 ?? anyone ? its an unstable equilibrium position but still an equilibriumposition, is that the reason? in opposition to a stable one when they are parallel.
@TheBudhenson5 жыл бұрын
Philippe... initially when the sample/patient goes into the static field, the nuclei orient along B0 also called the static magnetic field. When you impose the RF pulse, you USUALLY select to rotate the nuclear alignment by 90 degrees, but can actually select for any angle. In fact, the 'inversion pulse sequence' rotates the direction by 180 degrees.
