This course will introduce the basic concepts of biomedical imaging technologies routinely used in both medical practice and medical research. The topics will include a gentle introduction to the physical and physiological principles underlying fundamental medical imaging systems used in clinics (i.e.., X-Ray, computed tomography, magnetic resonance imaging, ultrasound, PET imaging). The course will end with a discussion on the ethics of the use of biomedical technologies.
The course will cover the underlying physical principles by which information about tissues within the body can be extracted in the form of signals, considering the major physical principles used: Transmission (e.g., X-ray), reflection (e.g., Ultrasound), emission (e.g., SPECT/PET) and resonance (MRI/fMRI). Then, it will proceed on to explain how these signals can be converted into images, i.e., full 3D volumes, where appropriate showing how common methods of ‘reconstruction’ are shared by some imaging methods despite relying on different physics to generate the ‘signals’. Finally, the theoretical lectures will cover concepts related to how medical imaging can be used to generate more than just pictures, but genuine quantitative measurements, and increasingly measurements of physiological processes, at every point within the 3D volume by methods such as the use of tracers and advanced dynamic acquisitions.
The main contents of the course will cover, radiation quantities and units, radioactivity, X-ray production and X-ray tube, interaction of radiation with matter, scattered radiation, X-ray film, digital imaging system, ultrasound imaging, X-ray, CT and image reconstruction, emission tomography: PET and SPECT, MR imaging, LASER imaging, electrical impedance tomography, bone densitometer, patient exposure and protection, quality assurance in radiology.
