Linear
The beam is rectangular, the piezoelectric crystal arrangement is linear, and the near-field resolution is good.
Types of ultrasonic transducers: linear probe
Second, whether the product is for 2D or 3D imaging affects the linear transducer's footprint, frequency, and applications.
The core frequency of the linear transducer for 2D imaging is 2.5 MHz to 12 MHz, and it also has a large footprint.
This transducer can be used in a variety of situations, such as:
-
Vascular analysis
-
Blood vessel visualization and venipuncture
-
Breast minuscule bits
-
Arthrogenous thyroid tendon
-
Laparoscopy and intraoperative
-
The assessment of body fat and muscle thickness for routine medical examinations and checks for locomotive syndrome
-
Ultrasonic velocity change imaging and photoacoustic imaging
The center frequency of the linear transducer for 3D imaging is between 7.5 and 11 MHz, and it has a large footprint.
This transducer can be used for: -
-
Breast
-
thyroid
-
vascular application arteria carotis
Phased Array
This transducer is named after the phased array piezoelectric crystal arrangement, the most widely used crystal.
The phased array transducer has a small footprint and a low frequency (its centre frequency ranges from 2 to 7.5 MHz).
The beam point is narrow at first, but it grows with frequency. In addition, the beam shape is nearly triangular, and the near-field resolution is weak.
What may the Phased Array transducer be used for?
-
Cardiovascular exams, including transesophageal examinations.
-
Examinations of the abdomen
-
Examinations of the brain
Endocavity
There is also the endocavitary ultrasound transducer type in the list of ultrasound transducer types. These probes allow you to undertake interior examinations on the patient. As a result, they are made to fit into specific body orifices.
Endovaginal, endorectal, and endocavity transducers (such as the Philips C10-4EC endocavitary probe shown below) are examples of endocavitary transducers.
They typically have tiny footprints and frequencies ranging from 3.5MHz to 11.5MHz.
Convex
The convex ultrasonic transducer, like the GE C1-6, is another form of ultrasound transducer and is also known as a curved transducer due to the curvilinear piezoelectric crystal arrangement.
Additionally, the transducer is suitable for in-depth inspections and the beam form is convex. Despite the fact that as depth increases, image resolution drops. Whether the product is for 2D or 3D imaging will also affect the footprint, frequency, and applications. For instance, the core frequency of the convex transducer for 2D imaging is 2.5MHz to 7.5MHz and it has a large footprint.
It can be used for tests like these:
-
Abdominal Vascular Nerve
-
Musculoskeletal OB/GYN
-
both transrectal and transvaginal
-
Identifying organs
The core frequency of the convex transducer for 3D imaging ranges from 3.5MHz to 6.5MHz and it has a large field of vision. You can use it to check your abdomen. There is a subtype of convex transducers known as micro convex in addition to the main kind. Typically, doctors would employ it in neonatal and paediatric applications because of its much smaller footprint.
