SONOSIM-Fundamentals of Ultrasound
A linear sequential-array transducer ______ - Answer--can operate within a range of frequencies
-sacrifices tissue penetration for better resolution
-has a higher operational frequency relative to a curvilinear transducer
A structure that is darker than its surrounding tissue is described as hypoechoic - Answer-true
Which of the following choices regarding posterior acoustic enhancement? - Answer-It causes the far
field of a fluid-filled structure to appear hyperechoic
The physics of ultrasound transmission and the properties of various tissues enable some tissues to
serve as acoustic windows - Answer-true
Transducers have a ranch of frequencies in which they can operate - Answer-true
the term "2D", "B Mode", "greyscale ultrasound" mean the same thing - Answer-true
Which of the following best characterizes the mirror-image artifact encountered when scanning through
the liver-diaphragm interface? - Answer-Mirror-image artifact is found below, or posterior to, the
diaphragm
