How Does Ultrasound Sonography Work?
Sound Wave Emission: A transducer, which is a small handheld device, emits high-frequency sound waves into the body. These sound waves are typically in the range of 2 to 18 megahertz (MHz), far above the range of human hearing.
Propagation and Reflection: The sound waves travel through the body and interact with different tissues. When the sound waves encounter boundaries between tissues of different densities, such as between fluid and soft tissue or soft tissue and bone, some of the sound waves are reflected back to the transducer.
Echo Detection: The transducer detects the reflected sound waves (echoes). The time it takes for the echoes to return to the transducer and the strength of these echoes (echo intensity) are measured.
Image Reconstruction: The echoes are processed by a computer to create real-time images on a monitor. These images are formed based on the pattern of echoes received, allowing visualization of internal structures and organs in the body.
Diagnostic Utility: Ultrasound imaging is highly versatile and used for various diagnostic purposes. It is commonly used during pregnancy to monitor fetal development and detect any abnormalities. In non-obstetric settings, it helps in evaluating abdominal organs (such as liver, gallbladder, kidneys), assessing blood flow through vessels, diagnosing conditions affecting the heart and blood vessels, and examining soft tissues and joints for injuries or diseases.
Safety Considerations: Ultrasound is considered safe because it uses non-ionizing radiation, unlike X-rays or CT scans, which use ionizing radiation. It does not pose the risks associated with radiation exposure and is generally painless and non-invasive.
