Linear Probe

Linear Ultrasound Probe Frequency

The linear array ultrasound probe has a linear arrangement of piezoelectric crystals and good near-field resolution, which can be used for superficial inspection. The frequency of linear ultrasound probes generally used for 2D imaging is 2.5-12MHz. Stork Healthcare's linear ultrasound probe frequency is 4-12MHz, which can be used for various superficial tissues, small organs, peripheral blood vessels, such as blood vessel examination, venipuncture, blood vessel visualization, chest, thyroid, tendon, etc.

Linear Vs Convex Ultrasound Probe

The center frequency of linear ultrasound probe is generally above 7MHz and the scanning depth is superficial. It's also named “Superficial Probe” because of usually being used for superficial organs and tissues such as the musculoskeletal, blood vessels, breasts, arteries, etc.

The center frequency of the convex ultrasound probe is generally 3.5MHz and the scanning depth is deep. It's also named “Abdominal Probe” because of usually being used for the liver, kidney, lungs, abdominal cavity, pelvis and chest cavity, etc.

Advantages of ultrasound convex probe compared with linear ultrasound probe:

1）The scanning field of the deep part is wider under the condition of equal body surface area.

2）It can effectively avoid the blind angle of scanning caused by the bone tissues such as ribs.

3）It is more conducive to squeezing the gas inside the visceral organ by using the surface of the arc-shaped probe, which also is conducive to both observation and elimination of scanning the blind corner.
