To reduce motion blur in infants and children, what should be the maximum pulse width in milliseconds?

To effectively reduce motion blur in infants and children, maintaining a maximum pulse width of 4-5 milliseconds is crucial. Infants and children often have higher levels of involuntary movement, making it essential to capture images in as short a time frame as possible. A shorter pulse width minimizes the time during which motion can blur the image, thereby enhancing clarity and quality.

Using a pulse width within this range strikes a balance between achieving sufficient image quality and minimizing motion-related artifacts. Pulse widths that are too long may allow movement to occur during the exposure, resulting in blurred images. This is particularly important in pediatric imaging, where precise diagnosis is dependent on the clarity of the images obtained.

In contrast, pulse widths longer than 5 milliseconds increase the risk of capturing motion blur, which is not ideal in this population. Thus, the selected range of 4-5 milliseconds is optimal for ensuring the highest quality images while accommodating the natural movements of younger patients.
