Ultrasonic piezo transducers ensure efficient production of particularly homogeneous aerosols with ultrasonic vibrations above 100 kHz. The ultrasound images obtained by a linear array transducer will be rectangular in shape while those obtained by a convex array transducer will be wider with increased depth. Ultrasound-guided breast biopsy reliably provides tissue samples that can show whether a breast lump is benign or malignant. Ultrasonic Obstacle Detection; Ultrasonic sensors are used to detect the presence of targets and to measure the distance to targets in many robotized processing plants and process plants. In most of the electrical systems, the input signal will not be an electrical signal, but a non-electrical signal.
