What Ultrasound Measures
Ultrasound measures sound waves that bounce off tissues. It also detects differences in density. These echoes create real-time images.
How Sound Waves Travel
Sound waves travel through the body at different speeds. They also reflect differently depending on tissue type. This variation forms the image.
Why Ultrasound Shows Soft Tissue Well
Ultrasound shows soft tissue well because sound waves interact strongly with fluid and muscle. It also avoids radiation. This makes it ideal for many exams.
Limitations of Ultrasound Physics
Limitations include difficulty imaging bone and air-filled structures. It also depends heavily on operator skill. Awareness supports accuracy.
