Medical imaging is a discipline which seeks to enable medical doctors and surgeons better do their job by providing them with images that shred insight in the human body's internals, either for diagnostic purposes or for guidance during therapy (eg surgery).
There are various open problems in medical imaging as of 2007.
MRI noise
Magnetic resonance imaging (MRI) creates high-resolution images of the body's internals by using a very strong magnetic field (which can be 20 000 times the Earth's magnetic field) generated by constant fast movement of coils inside the MRI scanner. This fast movement also generates a loud noise. Considerable research effort is done attempting to think of an innovative way to solve this problem and thus enable the creation of low-noise MRI scanners, but no study has so far proved fruitful. Therefore, at present, the only way to protect the patients entering an MRI scanner is to supply them with ear defenders.[1]
