Understanding Ultrasound Physics - SPI Exam Review – ARTIFACTS| 54 QUESTIONS| COMPLETE SOLUTIONS

Document Content and Description Below

While using a linear sequential array transducer during a color Doppler exam, the shape of the grayscale image is most often _______, Whereas the shape of the color Doppler portion of the image is ___... ____. A. rectangular, parallelogram B. rectangular, sector C. sector, trapezoid D. square, rectangular Correct Answer: A. rectangular, parallelogram The shape of a grayscale image using a linear sequential array is rectangular. However, the sound beams used for Doppler are steered at an angle, creating a parallelogram shaped region. What is the meaning of the term "analysis" in the context of spectral analysis of Doppler signals? A. Building a sophisticated signal from components B. building a simplified signal from components C. identifying the building blocks or components of a complex signal D. measuring a complex signal then modifying its information content Correct Answer: C. identifying the building blocks or components of a complex signal The term analysis defines the act of scrutinizing an object to determine what individual components are incorporated within it. In Doppler analysis, the complex signal is broken down into its more basic ingredients. The analysis of Doppler Spectra using _______ is most accurate. [Show More]
