Which of the following is a function of read zoom?

The function of read zoom is to magnify and display stored data. This feature allows sonographers to enhance specific areas of interest in an image after data has been acquired. By applying read zoom, the system can essentially enlarge a selected region of an image without needing to re-acquire the ultrasound data. This is particularly useful for examining small details or structures more closely, which enhances the overall diagnostic capability of the ultrasound study.

Read zoom relies on the existing data captured during the examination and does not affect the temporal resolution or involve any additional data acquisition, contrasting with functions that acquire and magnify new information or enhance temporal resolution. These processes would typically require fresh image data to be collected rather than manipulating already stored images.
