Compensation of magnetic field instability in weak field MRI-installation

There are the various sources of a magnetic field used in MRT-tomography. The magnetic field of electromagnets and solenoids can  have instability in time, so  received MRT images  can have characteristic artifacts.
The purpose of the given work is creating program for compensation of magnetic field instability. For weak fields this development was carried out for the first time.
To solve this problem medium MathCad 14 and Lab View have been used. Getting of test images (bulb with water) was performed on the training tomography.
During the work the corresponding program was written and investigated. It builds MR images, evaluates the stability field and reconstructs the image in case of instability.
