Which of the following is FALSE about the advantages of continuous-wave Doppler?

The statement that continuous-wave Doppler allows for more precise range-gating than pulsed-wave Doppler is inaccurate. In fact, one of the limitations of continuous-wave Doppler is that it does not provide range-gating. Unlike pulsed-wave Doppler, which can focus on a specific region of interest and measure velocities at that exact location (offering precise depth information), continuous-wave Doppler does not have this ability. It continually emits and receives a signal, making it incapable of distinguishing where within the gauge the signal is originating from.

On the other hand, continuous-wave Doppler has several advantages, such as not being affected by aliasing, which is a common issue experienced with pulsed-wave Doppler when measuring high-velocity blood flow. The signal-to-noise ratio in continuous-wave Doppler is generally favorable because it can detect continuous signals without interruption, enhancing the clarity of the readings. Additionally, continuous-wave Dopplers tend to be simpler devices and usually come at a lower cost compared to complex pulsed-wave systems.

These characteristics help clarify why the assertion surrounding range-gating aligns incorrectly with the principles of continuous-wave Doppler technology.
