What is a typical frame rate for B-mode real-time imaging? A. 1-9 kHz B. 10-50 Hz C. 100-200 MHz D. 200-300 Hz E. 0.05-0.9 Hz - Answer- B. 10-50 Hz <Frame rates are displayed in terms of Hz, a unit of frequency equal to one cycle per second. Although frame rates vary, typical real-time frame rates range from 10 Hz to 50 Hz. If the frame rate is 30 Hz, that means 30 frames are produced in one second. Faster frame rates are found with cardiac imaging> What component is necessary...
