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.
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.
There are hundreds of piezoelectric crystals in the convex ultrasound probe and the crystals are arranged in a convex arc to generate a fan-shaped sound beam and obtain a trapezoidal image. The imaging resolution improves with the scanning depth of the ultrasound convex probe increasing, which is beneficial for deep inspection. The frequency of convex ultrasound probes generally used for 2D imaging is 2.5-7.5MHz.Stork Healthcare convex ultrasound probe frequency is 2-5MHz, which can be used in abdomen, gynecology, obstetrics and the urinary system, etc.

Phased array transducer is named after the arrangement of piezoelectric crystals, which is the most commonly used crystal. It is composed of a plurality of separate piezoelectric crystals in an array, adjusting the position and direction of the focus with the electronic system controlling and exciting each crystal unit according to certain rules and sequences.
The beam spot of the phased array transducer is narrow but it will expand according to the application frequency. Additionally, its beam shape is approximate to the triangle and the near-field resolution is poor. The frequency of the Stork phased array transducer is 2-5MHz, which can be used for abdominal organs, heart, such as cardiac examination, transesophageal echocardiography, the abdominal examination also the brain examination, etc.
When comparing phased array probes to curvilinear probes, it is important to consider the desired type of scanning and the location of the application. If you have a long scan that covers an area with high-z (thick) materials, then a phased array probe may be more suitable for your application. Phased array probes also have unique performance characteristics (such as beam attenuation) that make them great for measurements in non-conductive mediums such as food. However, if you are looking to acquire fast measurements and need to maintain small spot sizes due to measurement principles such as Absorption or Secondary Electrons or mapping applications such as eddy current or metal loss, then a curvilinear probe would be a much better choice.
The footprint of phased array probe is smaller than convex transder although its frequency is also 2-5MHZ. The pahsed array transducer is ideal for cardiac and available for abdominal examinations.
