KNOWLEDGE AND UNDERSTANDING
The students will acquire knowledge of the physical principles underlying the operation of the main equipment used in the field of medical imaging and the methods of reconstruction and image processing.
APPLYING KNOWLEDGE AND UNDERSTANDING
Knowing how to interpret the documentation of the equipment used in the field of diagnostic imaging, how to use radiological imaging systems to produce phantom images used for quality control, how to use biomedical image processing software, how to derive the main figures of merit used for quality control.
The students will be able to understand the value of the contribution of the Radiology Technician in the medical environment in order to support the medical personnel in the use of medical equipment and cooperate with the Medical Physicists in the quality controls.
Students will learn how to expose their ideas organizing knowledge in a hierarchical manner. Through the technique of interactive lessons students will learn to exchange ideas with their colleagues and to illustrate effectively possible solutions to the problems.
LIFELONG LEARNING SKILLS
The students will develop a methodology of study and analysis that will allow them to interpret and deepen the problems of physics of medical imaging.
Knowledge of general physics, in particular electromagnetism.
Digital radiology, new sensors for radiological image, phosphor plates, photodiode-scintillator cristal assembly, semiconductor sensors.
Computer Assisted Tomography, theory of first-generation tomograph, mathematical basis for tomographic reconstruction, Radon theorem, convolution theorem, filtered back projection, Hounsfield numbers.
3D image reconstruction from tomographic sections, virtual reality display of the human body, tissue contouring
Magnetic resonance, magnetic dipole moment, the precession motion, the proton in the magnetic field, relaxation phenomena, relations between relaxation times and characteristics of the molecules, operation of the instrument for MRI.
Radioactivity, natural and artificial radioisotopes, in medical applications, the physical basis of Nuclear Medicine, the scintigrafo, the gamma camera, the main radioisotopes used in MN, the elution column for the technetium 99 metastable.
PET, operating principles, the PET scanner, the CT-PET system, radio-isotopes, the radiotracer FDG, the detector characteristics, the cyclotron, production of radioisotopes beta + emitters.
Ultrasound imaging, acoustic references, propagation of waves, laws of reflection and refraction, interference phenomena. Ultrasound imaging technology.
Theory: 34 hours
Tutorials: 6 hours divided into
Radiographic image simulation program: 2 hours
Tomography simulation program: 2 hours
Medical image processing: 2 hours
Verification of learning
The verification is done through a final examination, which ensures the acquisition of the expected knowledge and skills through an oral test.
The oral test will begin with the presentation of a topic chosen by the student on the course program. The teacher may interrupt the student to ask him to clarify or develop certain issues. Next, the teacher will pose questions to the students throughout the whole program of the course, to evaluate both the knowledge of theoretical parts and the ability to discuss how theoretical parts can be applied to concrete problems.
In order to pass the exam, the student should demonstrate knowledge and operational capacity in relation to the key concepts discussed in the course. A higher score will be awarded to students who demonstrate that they understand all the content of the course and have the ability to discuss how theoretical parts can be applied to real problems. Failure to pass the exam will be due to insufficient knowledge of the key concepts or of the technical language.
