Physics of Radiology
2nd Cycle Studies - Mestrado
• Theorectical lectures
• Computing, laboratorial and in the hospital environment practical classes
• Tutorials: student supervision in the preparation of the presentations and synthesis work to be done by students.
The course's main objectives:
- Provide students with solid knowledge on the basic physical concepts, dosimetric aspects and instrumentation of X-rays based imaging techniques for diagnosis and intervention;.
-Leading to the integration of basic knowledge to understand and relate the type of information that the imaging techniques can provide, the adjustable parameters of the equipment and their relation with the dose received by the patient and with the image quality.
- Acquisition of basic knowledge and skills to know how to evaluate i) the performance of the equipment in the various modalities that is included in the equipment quality control tests; ii) the image quality in the patient dose optimization perspective.
1 - X-ray sources for imaging; X-ray spectra.
2. Image quality evaluation: contrast, resolution, sharpness, SNR2 / D, DQE, MTF.
