What is the sampling rate commonly referred to as?

The correct answer is "sampling frequency," which refers to the number of samples taken per unit of time when converting a continuous signal into a discrete one. In the context of imaging, such as computed tomography (CT), the sampling frequency is crucial as it determines how accurately the digital representation can capture the nuances of the original signal. A higher sampling frequency leads to finer detail in the image because more data points are collected over a given period, effectively capturing variations and improving the image quality.

In various fields, including audio processing and digital imaging, understanding the sampling frequency is essential for ensuring that signals are accurately represented and that important information is not lost during the digitization process. This understanding is critical in CT technology, where precise imaging is vital for accurate diagnoses.
