Question

A mummy is placed in a MRI machine as shown in the figure below. A slice of thickness 20 cm (z = 20 cm - the center is at 5m) is selected for imaging using 2 different Zgradient settings as shown in case 1 and case 2. [6Pts] a. Calculate the Value of the magnetic field at the edge of the selected slice for each case (B1, B2, B3, and B4). b. Calculate the corresponding Larmor frequencies for the slide edge in both cases (f1, f2, f3, and f4). c. What is the bandwidth required for imaging case 1 compared to case 2 (f1-f2 >=< f3-f4). Approximate the gyromagnetic ratio of hydrogen to 42.6 MH(z)/(T)esla. Use: fo =  gamma ???? A mummy is placed in a MRI machine as shown in the figure below. A slice of thickness - the center is at 5 m
