Current diagnostic ultrasonography technology uses probes containing an acoustic ultrasound transducer (or several ultrasound transducers) to send pulses of ultrasound into matter. When the mechanical wave comes upon a boundary between two different materials (different acoustic impedance) energy is reflected back to the ultrasound transducer. This reflected energy echo is detected by theprobe. The time […]

Ultrasound machines used for diagnostic imaging or therapy emit ultrasound (high-frequency) waves that penetrate different types of tissue in the body. This kind of diagnostic equipment produces images without using harmful radiation as with x-rays. Due to the fact that ultrasound machines do not produce any ionizing radiation, it is very safe for human beings. […]
