This course begins with preliminary theoretical lessons that cover a broad range of ultrasound physics. We present the importance of understanding the physical basis and instrumentation of sonography.
The lessons will focus on the following learning objectives:
- to know the ultrasound physics and technology
- to identify the sonographic patterns of different tissues
- to recognize and explain common artefacts
- to describe ultrasound images using adequate vocabulary
- to select appropriate transducers and equipment settings
- to know the frequencies used in medical ultrasound and the effects on image quality and penetration
At the end of this module 1 the clinician will become familiar with ultrasound machines.
Physical principles of US wave
Diagnostic medical sonography is an imaging technique in which high frequency acoustic energy is transmitted into the body using a transducer in contact with the skin. The ultrasound wave is reflected from tissue interfaces of different densities.
US tissue interactions
The objectives of this lesson is to understand transmission of ultrasound through tissues, the interactions of ultrasound wave with body tissues.
Identification of different tissues and how is an US image constructed
Echography can only be correctly performed when users have a profound knowledge of the underlying technology.
In this lesson the common ultrasound artefacts and their significance in diagnostic imaging will be discussed.
Description of US Imaging Adequate Terminology
The objectives of this lesson are to understand the basic ultrasound imaging terminology and to observe the normal echogenicity patterns related to different organs and tissues
The terminology used to describe ultrasound findings is the description of the brightness of the structure.
