Errr, no? First of all, the kid might freak out from the AI glasses itself, if it could even wear it considering size, weight and other possible health limitations the child might have. They might not ever seen an AI set, they're jittery as it is, and you're introducing another set of variables and strange things they have to figure out.

Also, will they be able to comprehend that the things they are seeing in the AI image is an analogue of what will happen soon? It won't replace the "tactileness" of the machine and process, adults or companions can't guide them through a hologram in any immediate way.

To add to this this, many of the aspects that make MRI's uncomfortable for kids and even adults is all the physical sensations. Even the claustrophobia can get to many adults if they have never been in one of these machines. Also aspects such as the having the transmit/recoveree coil harness on the patient are physicals sensations you have to experience (for example sensing coils for the head) and really cant be emulated. The sound itself is also very physical as it is somthing not just heard but also felt by the patients. The sound is caused by electromechanical (fast high current switching of the electromagnet coils of the gradient coils) interactions in the operation of the machine itself so you might also feel the sound via the machine or coming from many directions in the bore.

I remembers from my class that there are some published works that design MRI sequences ("pattern" in which you operate the MRI machine to switch/modulate the electromagnets of the gradient coils, send RF pulses, and record the received RF pulses) in such a way that they reduce or don't cause the majority of the noise from the switching of the gradient coil in a typical MRI sequence.

There are and they have various names from vendors (whisper mode, quiet suite etc). Unfortunately these modes of operation are usually a bit limiting in terms of resolution and make sequences longer. They do reduce the noise.

By and large, if you give kids a movie to watch you’ll get 30 minutes of them remaining still.

Clinically, the application for noise reduction is often for patients whose hearing is at risk and can’t be protected effectively. Animals and patients with pathology which prevents earplug or headphone use etc.

Reading this makes me glad that you can't feel what the intense magnetic field does to the hydrogen atoms in you. (I don't know, I've never been in one)

Vs most hospitals won’t be able to build such models or won’t even consider it due to many factors.
