Martin Caon Examination Questions and Answers in Basic Anatomy and Physiology Third Edition Chapter 16: Waves, Light Waves, Sound Waves, Ultrasound (the Physics of) 16.1 Waves Mechanical waves (sound waves, waves on water) are a mechanism for transferring energy through a medium (the air or water) without transferring matter. Another definition is: A periodic disturbance in some property of the medium, the medium itself remaining relatively at rest. Waves have the following measurable p...

Sonography Canada CORE (Physics) | 2023/24 questions and answers what is a transducer? - anything that converts one form of energy to another form of energy what does an ultrasound transducer do? - converts electropotential energy into mechanical and mechanical energy into electropotential energy what is the curie point? - if a crystal is heated beyond the curie point (360 degrees for PZT) the crystal can lose piezoelectric effects what material is traditionally used for ultrasound tras...

Physics: Equipment: Ultrasound Questions and Answers 2023 What is ultrasound? Ultrasound describes sound waves oscillating at a frequency greater than 20 kHz (20,000Hz). Well beyond the range of human hearing. What frequency range is used in clinical ultrasound? Between 1-20 MHz (1 MHz = 1 million Hz) How are sound waves propagated? Sound waves are propagated through a medium by the vibration of molecules. They cause regular pressure variations with alternating...

Ultrasound Questions and Answers 2023 - high frequency sound waves beyond the range of hearing (20 Hz-20 KHz) What is ultra sound? mechanical energy as sound waves are transmitted through a patient (tissues) and returning echoes are detect what is the physics of ultrasound? - a constant velocity of sound within soft tissue even though differences - the speed of sound in all body tissues is 1540m/s - the ultrasound beam only travels in a straight line with a constant rate of at...
