Spin-Echo imaging sequence

  1. May 14, 2012 #1
    1. The problem statement, all variables and given/known data

    I have an image similar to the one given here with two types of material inside of it and I need to have at least one voxel in the image is entirely type B material (The smaller inside material). I am given all the dimensions on the material A and B but not told where material B is located inside of material A. I need to design a voxel size deltaX, deltaY, deltaZ and a scanning geometry that will guarantee getting a voxel of purely tissue B.

    hint: This part is mostly about geometry and the sampling theorem.

    2. Relevant equations

    Area of a cylinder?
    The cylindrical structure has its long axis parallel to zhat and has a length of 5mm.



    3. The attempt at a solution

    I understand how the pulses create the spin-echo effects, but no idea how to set up sampling or geometry for this sort of thing. Any hints would be greatly appreciated.
