What are the main factors influencing the quality of a CT image?

• A. Slice thickness and reconstruction algorithms
• B. Room temperature and patient demographics
• C. Type of scanner and technician experience
• D. Patient history and scan duration

Answer: (A)

The main factors influencing the quality of a CT image include slice thickness and reconstruction algorithms. Slice thickness refers to the width of the sections that the CT scanner creates during imaging; thinner slices generally provide higher detail and better resolution, allowing for improved visualization of structures. Reconstruction algorithms are mathematical processes used to transform raw data collected by the CT scanner into a reconstructed image. The effectiveness of these algorithms can have a significant impact on image quality, affecting aspects such as noise reduction, contrast resolution, and the ability to visualize fine details. Together, these two factors play a crucial role in determining how well the image represents the actual anatomy and pathology, making them fundamental components in the assessment of CT image quality. Other options, while potentially relevant in specific contexts, do not have the same direct impact on the fundamental imaging characteristics as slice thickness and reconstruction algorithms do.
