The progress of medical image processing technology has played a significant role in improving medical diagnoses and treatment techniques. Medical image processing technology in the narrow sense is the processing and analysis of medical images already attained, but in this course students learn about image processing in the broader sense, in other words everything from data collection to image formation, image reconstruction, processing, and analysis. The specific topics of this course are the properties of images obtained from medical image devices, image reconstruction techniques used by medical imaging equipment that use X-rays, and gamma rays, as well as the image generation and processing techniques of ultrasonic diagnostic equipment, and computer diagnosis support technology.
Students in this course learn how various conventionally studied signal processing technology and image processing technology are used in the medical field based on examples applied to specific modalities. Students build the knowledge necessary for aspiring information and communications engineers in the medical imaging field.
By the end of this course, students will be able to:
1) Acquire knowledge related to the fundamentals of the image reconstruction technique and the image processing technique.
2) Understand the practical use and application of the medical field.
3) Understand future subjects of those systems.

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
All materials used in class can be found on OCW-i.
Students will be assessed on their understanding of the medical images, the basic algorithms and the medical image processing methods.
Students’ course scores are based on class reports, exercise problems (50%) and final report (50%).
This class requires knowledge of fundamentals on the signal and image processing in undergraduate levels.
ICT.H421(Medical Imaging Systems) or some Medical Imaging Modalities background is desired.
