ERROR at 10:08. It is not AM radio at this frequency. AM radio band stops at about 1.5 Mhz. 68Mhz is in the VHF range (30 to 300Mhz). The radio frequency spectrum was set by ITU at the dawn of (broadcasting) time.

Okay...so I'm currently cross training in MR and my company is structuring a track based on my experience for future employees also wanting to cross train. I'm using the ASRT modules for my required structured education hours and I can not tell you how glad I am to have stumbled upon these videos. They're great. I'm going to recommend that we add them to the other supplemental materials. Thank you for doing this!

Hi sir.. I had one doubt The spinning action of proton is after applying radiofrequency Or before ( it has natural spinning process or not?)

@MRIPhysicsEXPLAINED

Hello, I think the term "spin" is one that's commonly used in MRI physics but can have multiple meanings so can be quite confusing. Every particle (protons in our case) have a quantum spin at rest (spin up or spin down). But the spins are randomly aligned in space. When we stick them in a magnetic field, we get a few of these to align along the magnetic field, but they aren't precessing. It is the RF pulse that makes these protons ("spins") precess in concert together about the Z-axis (confusingly also sometimes referred to as "spinning" about the Z-axis). We go into a little more depth into the equation that governs this alignment in the following episode: kzread.info/dash/bejne/qXidz9B8Yqi9kZs.html. Hope this helps.

Hi! I am interested in getting into the radiology field, most especially MRI. Do most of the physics that they teach you in school apply to what you actually do in the MRI field or you just have to know the basics and use common sense?

@MRIPhysicsEXPLAINED

Hello and congratulations on your interest in radiology, it's a great field to be in! By radiology field do you mean as a technician acquiring the exams, or as a radiologist reading them? Either way, both will have standardized exams that include some base knowledge of MRI physics. Unfortunately, this is typically in the form of random facts you'll need to memorize and which aren't very useful in actually understanding the physics, one of the reasons I made these videos. But in reality, only the engineers designing the machines will need to fully understand the physics and work with them on a daily basis. The rest of us are more users of the machine. Think about your car, a team of people behind the scenes did all the math, designing and testing to produce the car you drive, and you as the driver are the one working the controls to move and navigate the car. You really don't need to understand how the machine was engineered, just how to operate it. Radiologists and especially MRI technologists are the drivers of the MRI machine, working the controls to make sure the images are useful by understanding how changing parameters within the machine affect it's performance. If this sounds fun to you then definitely try to shadow a technologist or radiologist. If you would like to be a designer of the machine and live with the physics everyday, I would suggest studying engineering and look at jobs for companies that produce the machines such as Siemens or General Electric!

Local AM radio stations operate between 540 and 1700 kHz, not 68 MHz. FM radio stations operate between 88 and 108 MHz which is slightly higher than your example of a 1.5T magnetic field.

Thanks for the comment. This (should have been) already corrected with a caption that pops up during this segment saying the band is analog TV and into the FM range.
