NPRE 435: Radiological Imaging
Techniques to generate ionizing radiation useful in the imaging of solids and medical imaging. Theory and applications of biological and medical imaging modalities that use ionizing radiation: X-ray diagnostic methods such as plain film and digital, computer axial tomography (CAT); radionuclide imaging techniques such as positron emission tomography (PET), single photon emission computed tomography (SPECT), and gamma cameras. Theory and applications of materials imaging, including x-ray, electron, and neutron diffraction. Course Information: 3 undergraduate hours. 3 graduate hours. Prerequisite: NPRE 446.
§ Lab tour: We will have 2 lab tours during the semester to (1) the Molecular Imaging Center at the Biomedical Imaging Center (BIC) of the Beckman Institute, and (2) the Microscopic Suite at the Beckman Institute.
§ Term project: (1) Paper review project and (2) X-ray CT data acquisition and image reconstruction.
§ Quizzes and Exams: Two major exams and a few quizzes.
