Dual-Head Palm Ultrasound for Portable Medical Use

The probe contains piezoelectric ceramics, which utilize the piezoelectric effect to convert electrical signals into ultrasonic waves and receive echo signals. Other components include an acoustic lens layer (for focusing ultrasonic waves), a matching layer (for optimizing ultrasonic wave transmission) and a backing material (for reducing interference). Linear Array Head: Suitable for high-definition imaging of superficial organs. It features high resolution with a narrow field of view. Convex Array Head: Provides a wide-angle field of view, and is often used for the examination of deep organs such as the abdomen (liver, uterus).     CA Elements R (mm) Center Freq.
