The best contrast resolution will be available with which digital scan converter?

• A. 4 bits
• B. 256 shades of gray
• C. 32 shades of gray
• D. 16 bits

Answer: (D)

The best contrast resolution will be available with a digital scan converter that has a higher bit depth. In this case, 16 bits provide a higher bit depth compared to the other options listed. A higher bit depth allows for more shades of gray to represent the image, resulting in better contrast resolution. This increased number of shades of gray enables a more detailed and nuanced display of different tissue densities, which is essential for accurate diagnostic imaging in medical sonography. Option A (4 bits), Option B (256 shades of gray), and Option C (32 shades of gray) have lower bit depths compared to Option D (16 bits). Lower bit depths result in a limited range of shades of gray, which can compromise the ability to distinguish subtle variations in tissue densities and reduce the overall contrast resolution of the image.
