An echo machine, also called an ultrasound machine or echography system, is a medical device that uses high-frequency sound waves to create images of the inside of the body. It is a completely safe, non-invasive, and radiation-free diagnostic method used across many medical fields. The machine produces real-time visuals of organs, tissues, and blood flow, helping doctors detect abnormalities and monitor health conditions.

Echo machines are commonly used for pregnancy scans, abdominal examinations, heart evaluations (echocardiography), thyroid scans, pelvic scans, and vascular studies. During the procedure, a handheld probe is moved gently over the skin to capture images, allowing doctors to observe structures and measure their function.

This technology helps in early diagnosis, treatment planning, and continuous monitoring, making it essential for hospitals, diagnostic centers, fertility clinics, and general healthcare.
