Knowledge Point

Mechanical probe

A motor drives a rotating head whose shaft is located at the focal point of the probe surface to rotate in one direction. Two focusing transducers are embedded in the rotating head. When the transducer rotates to face the reflector, it emits ultrasonic pulses. After parabolic launching, a row of parallel linear scanning beams are formed, realizing mechanical scanning. Its advantages are that the sector-shaped mechanical scanning probe has a large field of view for far-area exploration, a small contact area for acoustic coupling with the human body, and the same tangential and lateral resolution. It is suitable for ultrasound examination of heart, small organs, ophthalmology, lumen ducts and abdominal organs.

Harmonic imaging

Harmonic imaging exploits non-linear propagation of ultrasound through the body tissues. When the frequency of emitted sound wave is f 0, the frequency of echo (due to reflection or scattering) includes f 0 (called fundamental wave), 2f 0, 3F 0 and so on The second harmonic (2f 0) has the largest energy.

Ultrasonic harmonic imaging (UHI) is based on the information of human body carried by the second harmonic in echo (reflection or scattering). Harmonic imaging without UCA is called native harmonic imaging or tissue harmonic imaging. Harmonic imaging using UCA (ultrasound contrast agent) is called contrast harmonic imaging.
