Ultrasound Basics Step 5, Part 2 Basic Physics - Self Test In relationship to ultrasound imaging, air will: Improve ultrasound transmission By being a strong reflector, air will be impermeable to transmission Have no effect on ultrasound transmission Can not be used in lung ultrasound due to the air content in lungs The number of cycles per second is the definition of Wave speed Frequency Hertz None of the above Diagnostic ultrasound transducers are basedon the physical principle of: Murphy’s law ALARA principle Doppler principle Piezoelectric effect None of the above Axial resolution of ultrasound is primarily dependent on the: Transducer frequency Power Frame rate Beam width Compared with a 2-MHz transducer, a 5-MHztransducer will have: A deeper tissue penetration A lower image resolution No difference in depth penetration or image resolution Both a better resolution image and a greater depth penetration A better image resolution and a lower depth penetration
