What three functions does information within the display field-of-view (DFOV) support?

The display field-of-view (DFOV) is critical in CT imaging because it defines the area of interest on which the image is focused and displayed. The first function it supports is multiplanar reformation (MPR), which allows for the reconstruction of images in various planes (axial, coronal, sagittal) from the original dataset. By using information within the DFOV, clinicians can generate these additional views, providing a more comprehensive understanding of the anatomical structures.

Moreover, the DFOV plays a vital role in optimizing image quality for interpretations, particularly for targeted assessments in specific areas. By focusing on the relevant data while minimizing the background noise from areas outside the DFOV, radiologists can gain clearer insights during their evaluations. This enhances the quality of the diagnostic process and aids in making informed clinical decisions.

While retrospective reconstruction and long-term storage in the archive servers are important components in the workflow of CT imaging, they are not directly functions supported by the DFOV. Retrospective reconstruction typically utilizes the entire dataset irrespective of display considerations, and data storage pertains to data management rather than specific imaging functions.
