Changing the reconstruction algorithm in CT imaging primarily affects how the raw data are manipulated to reconstruct the image. Reconstruction algorithms are mathematical techniques that process the data collected from the CT scanner to create the final image. Different algorithms can enhance certain features of the image, such as contrast, detail, or noise reduction. For instance, some algorithms might improve the visualization of soft tissue, while others may be better at highlighting bone structures.

The process of image reconstruction involves transforming the raw data obtained from the CT scans into a format that can be interpreted by radiologists. This transformation is crucial because it fundamentally determines the appearance and diagnostic utility of the final image. Consequently, utilizing varying algorithms will yield different imaging outcomes, underscoring their importance in clinical practice.

Other options, such as the type of imaging conducted or the speed of the CT scan, are not directly influenced by changes in the reconstruction algorithm. The type of imaging pertains more to the specific scan protocols or procedures employed, while speed is affected by factors such as the scanning equipment and settings rather than the algorithm per se. Additionally, the quality of contrast does not relate to reconstruction algorithms; instead, it pertains to the substances administered during imaging to enhance visibility of certain structures.
