Original Abstract
A high quality of magnetic fields is one of the basic prerequisites for a perfect operation of the MR tomographic scanner. Magnetic susceptibility of materials that are used for body implants causes much distortion in MR images. The paper deals with mapping the radiofrequency magnetic field induction in the vicinity of these materials with the aim of characterizing the magnetic field and comparing the results with fields simulated in the ANSYS program. Magnetic resonance method of radiofrequency magnetic field mapping was verified and optimized for both the characterizing of MR imaging detecting coil and the effects of electrical conducting samples. The designed method is based on optimized spin-echo imaging sequence with small flip angle.
Keywords
