    2. Teaching Staff Xiaoming Zheng Email:xzheng@csu.edu.au Phone:69 332068 Building/Room number: Building 30/Room 270 Consultation Tuesday:11:00am-1:00pm Thursday: 10:00am-12:00noon Hans Swan: To be tabled. Guest Lecturer: To be tabled

    3. Textbook and study notes Hashemi, RH & Bradley, Jr, WG & Lisanti, CJ 2004, MRI The basics, 2nd edn, Lippincott, Williams & Wilkins, Philadelphia. CSU MRI Study Notes. Lecturers notes.

    4. Assessment 1. Mid-session Test, 33% 2. Final Exam, 67%

    5. MRI Scanner

    6. Process of MR Imaging Put subject in big magnetic field (leave him there) Transmit radio waves into subject (about 3 ms) Turn off radio wave transmitter Receive radio waves re-transmitted by subject Manipulate re-transmission with magnetic fields during this readout interval (10-100 ms: MRI is not a snapshot) Store measured radio wave data vs. time Now go back to transmit radio waves into subject and get more data. Process raw data to reconstruct images Allow subject to leave scanner (this is optional)

    7. Topics Physical principles of MRI MRI instrumentation MRI pulse sequences - spin echo and an introduction to other sequences Spatial localization MR contrast weightings Factors affecting image quality MR safety Clinical MRI
