Physics in ultrasound imaging

WebbAs each patient is different, each ultrasound examination is different. In a very slim patient, ultrasound can penetrate the body easily, and you will get back a lot of echos. In an obese patient or one with emphysema, physics are way different, and overall, you will not get as many echos - image quality will be worse. Webb16 jan. 2012 · When ultrasound is reflected from tissues in the body and returns to the ultrasound probe, the reverse happens and the electrical signals generated are analysed and displayed as an image. How ultrasound is reflected Think about the example of shouting at a wall as described above.
