What are three potential benefits of increasing the CT acquisition thickness from 1 mm to 2 mm?

• A. Decreased patient dose
• B. Increased spatial resolution
• C. Increased beam coverage
• D. Increased scan time

Answer: (A)

Increasing the CT acquisition thickness from 1 mm to 2 mm can lead to a decreased patient dose, which is one of the primary benefits. When the collimation is adjusted to a thicker slice, the amount of radiation used per slice can be lower because the system can acquire data more efficiently. This means that the X-ray tube can operate at lower doses while still maintaining adequate image quality for diagnostic purposes. Additionally, acquiring thicker slices often reduces the total number of images that need to be obtained, which also contributes to a lower cumulative dose for the patient during the scan. While some may think that this change could negatively affect detail or diagnostic accuracy, the balance between image quality and dose reduction often favors thicker slices for certain clinical scenarios where high resolution is not as critical. Thus, when considering the overall impact on patient safety and comfort, increasing acquisition thickness has significant advantages in terms of radiation exposure.
