science departments who wish to learn the basics of medical
image analysis. The student enrollment is limited to 25.
(or programming experience with some high-level programming
language), Math 221, and some familiarity with introductory
concepts in probability and linear algebra. or by consent of the
introductory medical image processing and analysis techniques. Basic concepts without
extensive technical details or proofs will be covered. Students and researchers
should gain an easy to follow understanding of various
processing and analytic issues in medical image analysis. The focus will be on
awareness of processing and analysis concepts used in the field
and how some of these ideas can be implemented in Matlab to
facilitate image analysis.
Textbook & Language of Instruction
There is no textbook but reading
materials will be assigned and lecture notes will be distributed
online through the dropbox. Homework will be distributed online.
Link to the Dropbox folder:
will be assigned written and programming homework assignments (4
homework 30%), and two quizzes (60%) and final exam or project
(take home 10%). The grading scheme is
as follows: A (above 85%), AB (above 80%), B (above 75%), BC
(above 70%), C (above 65%), D (above 60%) and F (below 60%).
Sample homework problems:
1.Given longitudinally collected CT
images of the head, describe a sequence of processing and
analysis procedures for modeling mandible volume change.
Implement in Matlab a morphological procedure (e.g., open/close
filtering) for correcting topological defects in the volume
computation due, for example, to teeth fillings.
2.Given an existing implementation of
a generalized Hough transform, write code to adapt it for
detecting circular objects in microscopy images. Using training
data, perform evaluations assessing the accuracy of your method.
3. 0% tolerance for plagiarism.
Wikipedia defines it as "plagiarism is the wrongful appropriation
and stealing and publication of another author's language, thoughts,
ideas, or expressions and the representation of them as one's own
original work". This includes computer codes. Students are required
to work independently from each other and expected NOT to work
together for homework and exam problems.

of p-values and multiple comparisons. For clinically oriented studies,
it is often necessary to interpret the medical imaging
literature where the results are displayed in p-value maps
with multiple comparisons correction (mostly Bonferroni
correction, FDR and random field theory). We will only cover
how to compute them in Matlab, and how to interpret them,
and will not cover theoretical issues. Reading: Genovese, C.R., Lazar, N.A., Nichols, T.E., 2002.
