Independent Study CSL711 4 (3-0-2)

The objective is to learn material that is normally not part of regularly offered courses. A course outline along with details of the work to be performed are to be submitted by the student to the head of the department prior to the start of the course. The courses will be conducted under the guidance of a faculty. At most one independent study can count towards the degree requirements.


Physics of Medical Imaging CSL631 3  (3-0-0)

The course provides the necessary physics background that underpins day-to-day medical imaging physics activities. It is aimed primarily at new entrants to the profession, but should be of benefit to post-graduate students or post-doctoral research workers, wishing to deepen or re-establish their understanding of the physics of medical imaging. This course introduces the physics behind most of the common medical imaging modalities including x-ray, ultrasound, CT, PET, SPECT, optical imaging and MRI. There is emphasis on the physics of MR in this course as this is an active area of research in the field. Some math is required, Fourier Transform theory is helpful, but it will be reviewed in the course. The course will provide the student with a good understanding of the strengths and weaknesses of the different imaging modalities, what areas are still being developed, and the key applications of each modality.
