Part 4 of 4

A 180 degree pulse is applied to rephase the spins.

The signal (not visible) grows back again to a maximum.

this is a solution to a level in the cell phone game called apparatus. my dad came up with the solutions, i just filmed them. the game is not my own.

The only thing you need to copy this experiment is some aluminium foil and a very powerful magnet.

I happened to have access to a 1.0 Tesla MRI sys...

This is fun! Indoor skydiving. Wind speed up to 200km/hr

windspeed 188 km per hour

this is a compilation of my lessons

afterwards I received my certification and now I am a official indoor skydiver

Part 3 of 4

The yellow arrow represents the sum of the individual vectors (this is the actual MRI signal that can be measured).

It decreases as dep...

Part 2 of 4

The individual magnetization vectors start to de-phase because of interaction and magnet inhomegeneity

Part 1 of 4

The arrow represents the net magnetisation.

We observe spin and precession.

A pulse flips it over a 90 degree angle.

T1 relaxation caus...
