What is the width of a 3.5 and 5.0 MHz transducer?

• 13mm

• 19mm

• 18mm

• 16mm

Width and focal length or NZL are (a)   related

As the size (width) of the transducer increases the focal length or near zone length (a)  

Transducer frequency and transducer diameter are (a)   related to focal depth

As frequency (a)   ,the NZL increases.

Frequency and focal depth are (a)   related

• The focal length or near zone length depends on the (a)   of the transducer and frequency of the transducer.

• The focal length or near zone length depends on the size (width of the transducer) and (a)   of the transducer.

What is another name for the size of the transducer?

(a)  

As transducer diameter increases, focal depth (a)
