Question: 1 / 1100

What happens to image quality when system speed is decreased?

Image quality is increased

When system speed is decreased, image quality is increased. This occurs because a slower speed allows for longer exposure times, which can result in improved image detail and contrast. With a longer exposure, the detector has more time to capture the incoming photons, enabling better representation of the structures within the body. This enhanced clarity is particularly beneficial in complex anatomical areas where fine detail is crucial for accurate diagnosis.

Additionally, slower imaging systems are generally less susceptible to motion artifacts, as there is more time to accurately capture the image, leading to sharper, more defined results. Overall, decreased system speed facilitates better image quality, as it optimizes the balance between exposure duration and detection capabilities, ensuring that critical information is captured effectively.
