WebA diagnostic medical sonographer (also known as an ultrasound technician) uses a transducer to produce sound waves across specific parts of the body. These sound … WebThe sensor detects the sound reflected by a fixed reflector. The sensor switches as an object interrupts the distance between sensor and reflector. Advantage: Independent of object attributes, reliable signal even with extremely weak or diffuse reflective or sound-absorbing objects Ultrasonic through beam sensors WebMar 31, 2024 · These radial beams are called side lobe beams. Side lobe beams are low-intensity beams that surround the central beam. Side lobe artifacts are echogenic, linear or curvilinear artifacts. Strong reflectors include bowel gas adjacent to the gallbladder or urinary bladder. ultrasound artifacts ADVERTISEMENT: Supporters see fewer/no ads sunway construction
