CONTENT 1. The Spectral Doppler Display (650 words maximum) Give an account of the spectral Doppler imaging mode as follows: The overall spectral Doppler display incorporates two main components, a B-mode image and a Doppler spectrum. Obtain an image of a typical spectral Doppler display including the B-mode image and the Doppler spectrum (properly citing your source reference) and include it as a figure and then answer the following questions about it. Number your answers to correspond with the following question numbers. 1. Describe the main purpose of the spectral Doppler imaging mode. 2. Explain the purpose of the B-mode image in the display and how it is used 3. The vertical scale on the Doppler spectrum represents two parameters even though only one is shown. What are they and what are their usual units? 4. In your image of the display, draw and label the scan line on the B-mode image. SON4000-22sl assignment I Page 1 of 7 5. Label the sample volume on the B-mode image and explain clearly what it represents. 6. Define the range gate and explain the relationship between the sample volume, as indicated on the B- mode image, and the range gate, clearly distinguishing between the two. 7. Label the Doppler angle cursor and explain how it is used. 8. Explain the shape of the Doppler spectrum, the meaning of its peaks and troughs, and its variation with time. 9. Find and include as a separate figure another image showing spectral broadening on the Doppler spectrum. Explain what spectral broadening is and give two possible causes of spectral broadening. 2.
