Maravillas de la medicina: ecografía

Ultrasound, developed by Ian Donald in the 1950s, uses high-frequency sound waves to create images of the body's interior. Inspired by sonar used in nature, it measures distances through sound echoes and converts them into images. Initially used to monitor fetuses, ultrasound can diagnose potential issues early and provide 3D images. Beyond pregnancy, it helps detect bladder stones and assess heart conditions. Its ease of use and safety make it a vital diagnostic tool.
