4. Ultrasound B-mode Imaging. The maximum frame rate in B-mode ultrasound imaging (illustrated below) is limited by the time needed for echo collections (i.e., visualization depth) and number of acoustic lines per frame. If the maximum visualization depth is D, the speed of sound in tissue is c, and each image frame consists of N acoustic lines. (10 points) 3.5C40H74.00 Abdomen 100% 24dB RS3 12.0cm 22fps Text a. What is the maximum frame rate? b. Are pulsed ultrasound waves or continuous ultrasound waves in typical B-mode imaging? Why? c. What are the pros and cons of using high frequency (say 5-20Hz instead of 2-5MHz)? d. Should we use low frequency (2-5MHz) or high frequency (5-20MHz) for ophthalmology and pediatric imaging?
