(MENAFN- P&S Intelligence) Normal human hearing ranges between 20Hz and 20000Hz. Sound waves having frequencies above the top audible range of human hearing are referred to as ultrasound. Beyond 20 kHz and up to many gigahertz, ultrasound equipment operates.
The initial examination of bat echolocation by physiologist Lazzaro Spallanzani in 1794 served as the inspiration for ultrasonic physics. Jacques Currie and Brothers Pierre make the discovery of piezoelectricity, which serves as the foundation for ultrasonic transducers, in 1877.
In the detection of submarines during World War I, ultrasonography is reported to have had its first practical use. Ultrasonic devices were first employed in a variety of industrial applications, including mixing, cleaning, and measuring distances and items.
The use of ultrasound in medicine began considerably later, in the 1930s and beyond, and has since advanced significantly.
The following types of ultrasound equipment used in hospitals are frequently observed:
• Sterilization & Cleaning
• Therapeutic
• Diagnostic
When doing ultrasonography, high-frequency sound waves are utilized to produce pictures of anatomical structures. These images are then evaluated by medical professionals to check for anomalies.
With the use of this technology, it is possible to identify a variety of chronic disorders that affect vital body components including the heart, joints, and abdominal arteries. Additionally, it is among the safest non-invasive methods for organ inspection.
By seeing the body's tissues and organs, this approach is frequently utilized for minimally invasive diagnostics. For fluid management, it is also utilized in interventional radiology.
