Which type of zoom is a preprocessing function that provides more pixels in the region of interest, resulting in superior spatial resolution?

Read magnification
Read zoom
Temporal resolution
Write zoom

The correct answer is: Write zoom

Write zoom is a preprocessing function that provides more pixels in the region of interest, resulting in superior spatial resolution. This type of zoom works by increasing the number of pixels dedicated to a particular area of the image, allowing for greater detail and clarity in that specific region. On the other hand: - Read magnification refers to the postprocessing function where an area of interest on the image is enlarged by resampling pixels, which does not affect the original image's spatial resolution. - Read zoom is not a standard term in the field of diagnostic medical sonography. - Temporal resolution refers to the ability of an imaging system to capture moving objects accurately over time, which is unrelated to spatial resolution or zoom capabilities.
