Medical Central: The Possible Future Of Medical Imaging

I read more on Medical Imaging. We covered an interesting concept: the possible future of Medical Imaging!

The Possible Future of Medical Imaging
The science of Medical Imaging has been going at a fast rate... and getting much (extremely) faster with developments in technology and the Medical Imaging ways! It started off with X-Rays, and has boomed significantly. It may be possible that soon we'll be using scanners and devices that we see only in sci-fi movies! Devices include extremely tiny robots that can either be endoscopes or surgery-doing devices, VR goggles that can help surgeons in the surgery room, handheld scanners that can see inside the body, and the book even suggests a magnetic device to shut down the pain centers of the brain for a short bit!
Already, advanced imaging is going up. Scientists are working on a way called HUTT, which is an advanced version of Ultrasound, which should even figure out different tissues by just figuring out how the sound changes when it hits stuff in the body! They're even working on better X-Rays... double detectors should be better than single-detectors, and make better images with less X-Rays (according to the book). And open-sided MRI Scanners are already in use, as mentioned in the last post. And work is being done to figure out how to make cheaper and smaller MRI Scanners. There's a device out now that may be the trick, and is smaller and cheaper.
They are also working on a way called "optical imaging" in the book, which is similar to Ultrasound and HUTT... except it uses a long electromagnetic wave called infrared light to see inside the body! It can tell different tissues apart the same way HUTT does (except with infrared light). Optical Imaging is actually good for babies, because they're too jumpy to go through and MRI, and are way too sensitive to X-Rays.
Scientists are also working on a device called TMS. TMS uses magnetic waves to stimulate or "turn off" parts of the brain. Scientists think that this can be used to take care of depression. It may also possibly be the thing that will be used in the future as a pain-reliever that's safe, since it may shut down the brain's areas that deal with pain. It can be used to map out the brain, since stimulates areas, and scientists can map out that stimulation (according to book). fMRI and another method is used to check this thing and its effects out.
It may be possible that Medical Imaging jumps up so much, that it may be able to read a person's thoughts! This would be done to seeing certain patterns in the brain, and figuring out what these patterns mean, figuring out the person's thoughts! Some scientists fight against this, though. Why? Apparently, even when two patients are thinking about similar things, their brains will do different signal-patterns!
