Types of Ultrasound Probes

linear probe for ultrasound machineThe footprint size is large and the frequency high (7 – 18Mhz).
The shape of the beam is rectangular (see image) and the near field resolution good.
Typically used for superficial examinations of vascular, small parts, nerve, musculoskeletal, and breast.


Convex probe for ultrasound machineOr curved probes. The footprint is large and the frequency low (2.5 – 5Mhz). The beam shape is convex (see image).
Good for in depth examinations, although the image resolution decreases when depth increases.
Typically used for abdominal, vascular, nerve, musculoskeletal and GYN/OBS exams.
There is a subtype called micro convex with a much smaller footprint, which is typically used in neonatal and paediatrics.


Phased array probe for ultrasound machineAlso called sector probe. It has a small footprint and low frequency (2 – 8Mhz). It has a narrow beam point (see image), which can expand depending on the applied frequency. The beam shape is almost triangular and the near field resolution is poor.
Typically used for acoustic windows in the cranium or intercostal Spaces.


Internal probe for ultrasound machineAnother type of probe is the endocavitary, which provides the opportunity of performing internal examinations of the patient. Designed to fit in orifices for specific purposes. For instance endovaginal, endorectal, and endocavity. They typically have small footprints and the frequency vary in the middle range (3.5 – 11.5Mhz).
The transoesophageal probe produce images of the heart through the oesophagus. It also has a small footprint and a middle frequency (3 – 10Mhz)
In addition there is a number of probes that are designed for surgical use, like laparoscopic probes.


As mentioned above, the TEE probes can be applied for internal examinations, often applied in cardiology to obtain a better image of the heart. The transoesophageal probe produce images of the heart through the oesophagus. It also has a small footprint and a middle frequency (3 – 10Mhz). Moveable “head”


Pencil probeAlso called Doppler probe. It is used for measuring blood movement and sound. It has a small footprint and uses low frequency (typically 2 – 8Mhz).


How Much Does an Ultrasound Probe Cost?

The price of a probe varies from type to type and depends on the condition. At LBN Medical, we have a fixed standard, which applies to each probe sold. We have a huge selection that includes both new, demo, and used probes. Furthermore we buy large bulk orders, which ensures that we have a probe for you within your budget.

Needs repair in either strain / lens / cable / housing cracks


Rule of Thumb When Buying Ultrasound Probes

When buying an ultrasound probe, there are some good advice to follow:

  • Double check that the probe you want to buy is compatible with the system you have. You can use a probe guide, or ask our sales team.
  • Low frequencies (between 2,5 and 7,5) gives a longer image distance, but lower image quality 3MHz = ca. 8 cm.
  • Higher frequencies (above 7,5) gives a shorter image distance, but a better quality close to the surface (7,5MHz = 20 cm).
  • A black line in the screen of the ultrasound system will most likely mean a dead crystal inside the probe.
  • A shadow on the screen of the ultrasound system could imply a weak crystal inside the probe, which does not generate the necessary vibration.
