M-Mode ultrasound

M-Mode ultrasound, or Motion Mode ultrasound, is a technique that captures a single line of ultrasound images over time, showing how structures like the heart move. It provides a dynamic view of internal movements, allowing doctors to measure how quickly a heart wall or valve moves during each beat. By doing so, it helps assess the heart's function, such as its contraction strength and valve operation, with high temporal resolution. M-Mode is often used alongside other ultrasound methods to give detailed timing and movement information crucial for diagnosing cardiac conditions.
