20 lip 2014 · Basic Principles of Ultrasound. Objectives • Define Scope of Practice • Understand Principals • Understand Physics • Understand Transducers • Understand Terminology • Understand Artifacts.
an electrical current is applied to the crystal (piezo electric) component within the transducer face. current is then converted to mechanical (ultrasound) energy and transmitted to the tissues at very high (megahertz) frequencies. The ultrasound energy produced then travels through the tissues as pulsed, longitudinal, mechanical waves
22 paź 2014 · Ultrasound Imaging • An ultrasound transducer provides brief pulses of ultrasound when stimulated by a train of voltage spikes of 1-2 msec duration applied to the electrodes of the piezoelectric crystal element. • An ultrasound pulse • A few cycles long: 2-3 cycles.
