PPT-Magnetic Resonance Imaging

Shi Chen amp Pan Hui Chapter 13 Outline We fi r st explore the instrumentation necessary to create MR images Then we present the image formation process Imaging equations Computer algorithms. Traditionally clinical imaging exploits the contrast due to differences in spin density spinlattice relaxation T and spinspin relaxation T between normal tissues and pathology However other contrast mechanisms such as susceptibility magnetization In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir Principle first observed in 1946. Used for spectroscopy and imaging . Imaging techniques are a form of tomography, where slices are ’cut’ and depict. MRI utilizes signals from the body . MRI is non-ionizing, operating in radiofrequency range, unlike CT, PET, SPECT. pp. 487 - 493. Mr. Richter. Agenda. Podcast Check. Questions about 13.1 Sound Waves. Upcoming Schedule. Notes:.
