Work deals with methods of calibration of multi-center study of magnetic resonance imaging. Magnetic resonance is the phenomenon of the substance in a magnetic field of induction B0 delivers energy in the form of RF pulse with the Larmor frequency and thus to excite particles to higher energy levels. Calibration can be performed using the distinctive and homogeneous RF phantoms. Furthermore, we can perform calibration using image registration. To calibrate the images by registering the work described in the classical linear (affine) and nonlinear. Listed below are the simulators, which are also useful for modeling various artifacts.

Strategies on informed consent process and capacity monitoring for mild dementia research are at developing state. We reflected on our experience and found that the successful collection of informed consent and full participation of PwD required the involvement of familiar healthcare professionals/care workers/staff at the recruitment and data collection stages and this needs to occur in an active support environment. Time is another important factor affecting the success of the study.
