The results really look rather blurry compared to the MRI... Presumably that's just a matter of better system modelling to fix?

- Guestmodinfo 4mo agoMRI is done using X rays which have very very small wavelength compared to sound. And resolution of images i.e. less blurry varies inversely proportional to the wavelength. Yes some algo can make slightly better but I am certain that nothing can beat x rays in clarity for humans
- elric 4mo agoNo X rays are involved in MRI.
- FeteCommuniste 4mo agoMRI uses RF wavelengths, which are measured in meters. Ultrasound waves are measured in fractions of a millimeter. Wavelength is not the relevant factor here.
- jandrewrogers 4mo agoYou are thinking of CT scans. MRIs use strong magnetic fields and MHz-range radio waves.
- jedimastert 4mo agoEven if it's not the same resolution there's still benefits, a bit one that it will likely be WAY less expensive, both upfront and in maintenance, even after building the water tank. It might also replace a fair amount of routine ultrasound usage because of the reduction of operator skill. Also, there's plenty of people who can't be in MRI machines, and likely a lot safer for everyone else.
