Question: 1 / 615

What effect do smoothing algorithms have in CT imaging?

Enhance spatial resolution

Reduce metal artifacts

Smoothing algorithms in CT imaging primarily serve to reduce noise within the images, which can be particularly beneficial in areas where metal objects are present. Metal artifacts often result from the presence of high-density materials in the imaging field, causing streaking or distortion in the resulting images. By applying smoothing algorithms, the effects of these artifacts can be diminished, leading to clearer and more diagnostic images.

While enhancing spatial resolution, increasing the number of shades of gray, or improving x-ray exposure techniques are important aspects of CT imaging, these are not the primary function of smoothing algorithms. Rather, the role of smoothing algorithms is focused on improving image quality by mitigating the impact of noise and artifacts, especially where metal interference may complicate accurate interpretation.
