ultraäänikuvat
Ultraäänikuvat, known in English as ultrasound images or sonograms, are a non-invasive medical imaging technique that uses sound waves to create images of internal body structures. This technology relies on the principle of echolocation, similar to how bats navigate. A transducer, a handheld device, emits high-frequency sound waves into the body. These waves then bounce off different tissues and organs, returning to the transducer as echoes. The timing and intensity of these returning echoes are processed by a computer to generate a real-time image displayed on a screen.
The sound waves used in ultrasound are far above the range of human hearing, typically ranging from
Ultrasound imaging is widely used in various medical fields. In obstetrics, it is crucial for monitoring fetal
