For Echocardiography, color Doppler frame rates should be kept 17 Hz or above and preferably in the 20-30 Hz range. Every ultrasound machine has a numeric display of the current frame rate, which can range from less than 10 Hz to more than 60 Hz. Above: Image data area with FPS (Frames Per Second) and other adjustments.
To display 24 frames per second on a TV with a 120hz refresh rate, each frame is repeated 5 times every 24th of a second. To display 24 frames per second on a TV with a 72hz refresh rate, each frame is repeated 3 times every 24th of a second. To display 30 frames per second on a TV with a 60 hz refresh rate, each frame is repeated 2 times every 30th of a second.
