This course mainly focuses on learning the application of related theories such as signal processing and image processing in the field of biomedicine, and uses practical problems in biomedicine. The students taking the course will learn to judge the number and location of cancer cells in terms of images, such as image analysis of tumor slices. In terms of signal processing, we will let students actually operate blood oxygen sensors, and quickly let students understand medical imaging and signal processing. In the lesson, we not only teach the concept of medical imaging and signal processing, but also need to design the bio-measurement system by hand, to cultivate students' ability to combine practice and theory.
