Which method enhances imaging resolution in digital radiography systems?

Increasing pixel bit depth enhances imaging resolution in digital radiography systems by allowing for a greater number of shades of gray to be represented in an image. Pixel bit depth determines how many different intensity levels can be assigned to each pixel. A higher bit depth means more bits per pixel, which translates into a finer gradation of shades, improving the contrast and overall clarity of the images produced. This is particularly important in medical imaging, where subtle differences in tissue density need to be accurately depicted for diagnostic purposes.

While image magnification can make structures appear larger, it does not necessarily improve the resolution of the original data, as the inherent quality of the image data remains unchanged. Image compression reduces file size and can sometimes lead to loss of detail, while using a smaller detector size may negatively impact spatial resolution due to fewer pixels being utilized to capture the same area, potentially leading to a decrease in image quality.
