On SDCT, what pitch can you not go above?

The question pertains to the acceptable pitch limits in Single Detector Computed Tomography (SDCT). In SDCT, the pitch refers to the distance the table moves during one rotation of the scanner relative to the width of the x-ray beam.

The correct answer indicates that a pitch of 1.5 is the maximum allowable setting for SDCT. If the pitch is set higher, such as 2.0 or 2.5, it can lead to insufficient data acquisition for image reconstruction, resulting in increased noise and decreased image quality. This is particularly crucial because SDCT relies on optimal data collection for accurate and precise imaging.

By adhering to a pitch of 1.5 or below, technicians ensure that the scanner collects enough data in a given time frame to create a high-quality image without compromising diagnostic utility. Understanding the limitations of pitch is essential for maintaining image fidelity and ensuring patient safety in scan protocols.
