Biomedical imaging is central for diagnosis and therapy, as images give the user the possibility to immediately interpret complex and large data sets. In today’s imaging systems for biomedical applications, these are processed from information retrieved from ionizing radiation (nuclear medicine, X-rays) or non-ionizing radatopn (ultrasound or magnetic resonance imaging). The current trend is that biomedical images has an ever increasing role not only for diagnosis and therapy, but also to gain an understanding of the functions of the human body as sick or healthy all the way down to a molecular level. It is therefore important that the engineer in medicine and technology acquire an understanding of the basic principles behind these systems in terms of image generation, constraints and opportunities, applications and any related health risks..

Nuclear medicine: The principles behind nuclear medicine. The Scintillation camera, PET / SPECT - Basic principles of data collection for tomographic image reconstruction. Radiopharmaceuticals and internal dosimetry. Quality control.
Radiology: Generation of bremsstrahlung, X-rays, X-ray spectrum and filtering, the X-ray image. Radiation field, Radiation quality parameters (HVL, spectra). Primary and secondary radiation, contrast agents. Detectors (emulsion, intensifying screens, image plates). Image intensifiers. Direct digital detectors. Computed tomography, reconstruction algorithms, the CT number. Clinical applications of X-rays. Image quality versus the absorbed dose to the patient. DICOM image archiving in radiology. Quality control.
Magnetic resonance imaging: Brief history. NMR-related nuclear physics introduction including the concepts of magnetic resonance, spin population and signal generation. Basal contrast parameters: proton density, T1, T2 and T2 * relaxation. The signal detection and image reconstruction by Fourier transform. Basal pulse sequences, i.e., spin echo, gradient echo, inversion recovery, and their typical contrast properties at various machine settings. MR safety and practical risks.
Ultrasound: Physics, transducer technology, ultrasound scanner architecture, Doppler, safety and artifacts.
Grading scale: TH - (U, 3, 4, 5) - (Fail, Three, Four, Five)
Assessment: For a grade 3 the following parts must be passed: practical laborations with reports, as well as a written exam.
The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
