The 'Introduction to BioSignals and BioImages' course initiates the students into a basic understanding of how to detect, obtain, record and analyze the different BioSignal and BioImages that can be later on used in pre-clinical and clinical applications. We will learn about the physical and physiological origin of the different signals and images. During this course we will explore different modalities, such as ECG, EEG, MRI, CT or PET among others. We will study the physical devices, tools and methods that enable the acquisition and recording of their signals and images.
