Bioengineering 280A: Announcements - Fall 2004

  1. (9/30/04) Homework 1 has been corrected
  2. (10/11/04) Homework 2 has been corrected (For MATLAB problem 4, ifft should read ifft2)
  3. (10/13/04) Homework 2 has been corrected again (For MATLAB problem 4, x and y resolutions were sswitched).
  4. (10/18/04) Homework 3, problem 2 has been slightly reworded for clarity.
  5. (10/26/04) Midterm: 4b) Change G(kx,ky) to G(kx,ky,y) 4c) Change G(kx,ky) to G(kx,ky,x)
  6. (10/27/04) Midterm: Problem 2: It's okay to leave the answer as a convolution. Just do your best job in sketching the answer (or use MATLAB). Yesterday's material on Gibb's artifact may help you with the sketch.
  7. (10/27/04) Midterm: Problem 3d: There is a typo here. It should say to minimize the number of samples of H(kx,ky). The idea here is to think about how you can move G(kx,ky) in k-space to minimize the number of samples required. Sorry about that!
  8. (10/27/04) Corrected version of slide 28 for MRI lecture 3. Np was changed from 128 to 256.
