Ultrasound Orientation T2 Handbook of Critical Care and Emergency Ultrasound YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-160489-5 LK accessanesthesiology.mhmedical.com/content.aspx?aid=56300109 RD 2024/10/07 AB Ultrasound orientation is essential to understand what is being seen in point-of-care ultrasound. There are two key aspects: how the indicator is oriented relative to the screen and how the probe and indicator are placed and oriented relative to the patient. As described in Chap. 2, the conventional ultrasound image is a two-dimensional plane composed of frames made up of scan lines that are updated many times a second to create a moving image.
