What are the typical frequency values utilized in clinical imaging?

The range of 2-15 MHz is commonly used in clinical imaging due to the balance it provides between image resolution and tissue penetration. Higher frequencies, such as those at the lower end of this spectrum, are capable of producing images with excellent spatial resolution, which is essential for visualizing superficial structures, such as the thyroid or breast tissue. However, higher frequencies also have lower tissue penetration capabilities, making them less ideal for deeper structures.

On the other hand, frequencies at the upper end of 15 MHz can be beneficial for detailed imaging of small or superficial structures without significantly compromising the quality of the image. This frequency range is widely utilized in various applications, including abdominal, obstetric, gynecological, and cardiac ultrasound, where the pursuit of clarity and fine detail is crucial.

Other frequency options do not encapsulate the typical range used for general clinical applications as effectively. Frequencies below 2 MHz have applications primarily in specific scenarios such as deep tissue imaging but do not provide the detail necessary for most clinical imaging purposes. Frequencies above 15 MHz tend to be used in specialized areas, and their use is limited by the superficial nature of the structures they can adequately visualize. Therefore, the selection of 2-15 MHz aligns with the requirements of
