LEARNING OUTCOMES
The course aims to present and analyze the processes involved in the making of the X-ray image. It also aims at the illustration and the study of qualitative characteristics of X-ray image. Students should be able to display knowledge and comprehension of the basic science topics. More specifically, they should:
- Describe the interactions of radiation with matter.
- Analyze how the x-ray tube produces radiation and how the X-ray beam is affected by the exposure parameters (KV, mA, sec, filter, generator) selected in the control console.
- Describe and understand the technological advances in equipment (generators) used in diagnostic radiology.
- Understand the creation of x-ray images, the quality characteristics of radiological
image and the contribution of parameters involved in imaging.
The course objective is to link the theoretical background knowledge with the knowledge of parameters that can be adjusted in order to improve imaging.
