What is a Transducer?
A transducer is a device used in ultrasound machines to create images of internal organs. It works by sending out sound waves and then picking up on echoes that bounce back. These echoes are turned into images on a screen (part of the ultrasound machine, not tranducer) which helps doctors see what’s going on inside the body. Different types of ultrasound transducers can be used for different purposes like fetal monitoring, cardiac check-ups, or skeletal muscles.

Types of Ultrasound Transducer Probes
Transducers come in different types. Each designed for a specific imaging need. Here’s a simple breakdown of different types of ultrasound probes:
1. Linear Transducer:
- Shape: Flat, rectangular
- Frequency Range: High (5-18 MHz)
- Imaging Depth: Shallow to medium
- Applications: Best for looking at muscles, tendons, and blood vessels close to the skin. Often used in dermatology clinics and small organ imaging.
2. Curvilinear Probe:
- Shape: Curved
- Frequency Range: Lower (2-5 MHz)
- Imaging Depth: Medium to deep
- Applications: Great for abdominal scans, pregnancy check-ups, OB/GYN scans. The curved shapes help to give a wide view for seeing larger areas.
3. Sector Probes:
- Shape: Pie-shaped
- Frequency Range: Low to medium (2-5 MHz)
- Imaging Depth: Medium to deep
- Applications: Mostly used for heart imaging. They give a wide view and are good for looking at tight spaces in the body.
4. Phased Array Transducers:
- Shape: Small and compact (with a sector-shaped tip)
- Frequency Range: Medium to low (2-5 MHz)
- Imaging Depth: Medium to deep
- Applications: It is perfect for real-time heart imaging. The small size helps doctors see the heart from different angles.
5. Endocavity Probes:
- Shape: Made for insertion into body cavities
- Frequency Range: High (5-7 MHz)

6. Transvaginal probes:
- Shape: Thing and long, designed for internal use
- Frequency: High (5-8 MHz)
- Imaging Depth: Shallow
- Applications: Specifically for gynecological exams, these probes provide clear images for the uterus and ovaries, helping in women’s health assessment.
7. Transesophageal Probes:
- Shape: Long and flexible
- Frequency Range: High (3-7 MHz)
- Imaging Depth: Medium to deep
- Applications: These are best to get clear images of the heart from inside the esophagus, especially in heart exams.
8. 3D/4D Probes:
- Shape: Varies, with advanced technology
- Frequency Range: Similar to curvilinear and linear probes
- Imaging Depth: Varies with probes
- Applications: Creates 3D and 4D images. Mainly used in fetal monitoring scans to monitor the baby’s health in detail.
Dos and Don’ts While Cleaning a Transducer
Do’s:
- Always use approved cleaning solutions recommended by the manufacturer.
- Gently clean the transducer and avoid exerting force to prevent any damage.
- Use a soft cloth (or sponge) to wipe the tranducer. Never use an abrasive material. It will affect the sensitivity of the probe.
- After cleaning, rinse it thoroughly with sterile water to remove any cleaning residues.
- Disinfect after every use. Especially for transducers that come into contact with mucous membranes, like transvaginal probes.
- Regularly check the transducer for cracks or wear as they can harbor bacteria.
- Make sure the transducer is thoroughly dried according to the manufacturer’s guides.
Don’ts:
- Avoid using bleach, alcohol, or any non-approved cleaners that can damage the transducer at all costs.
- Never immerse the transducer in water, unless it is water resistant. This can damage the internal components.
- Don’t use scouring pads or rough materials that can scratch the surface.
- Follow the full recommended cleaning and disinfection steps without skipping any.
- Ensure the cleaning agents are compatible with the specific transducer mode.
Don’t use hot water when placing the transducer near heat sources to dry.

Buying Guide: How to Buy the Best Ultrasound Probe
Here are a few tips that will help you make the best decision when buying a probe.
Why do you want one?
When getting a transducer probe, it’s very important to understand your clinical needs. Look at the applications of different probes and see which fits right to your needs. Different probes are designed for different purposes. Look at the frequency range for each. High frequency ultrasound is best for getting clear images for organs closer to the skin. Whereas, a low frequency in ultrasound is better for deeper areas. Make sure the probe you choose works with your current ultrasound machine.
How much are you willing to invest?
On the budget side, it is easy to go for the cheapest option. But investing in a good-quality probe can save you more money in the long run. High-quality probes usually provide clearer images and last longer.
Also, consider the overall cost, including any future maintenance or repairs. A reliable probe might cost more upfront but will handle a wide range of tasks, making it a smaller choice over time.

Case Study
A mid-sized healthcare facility in southeast asia, was using outdated ultrasound systems with older probe models. This was causing longer wait times, less accurate diagnosis, and increased anxiety for both staff and patients.
The management decided to invest and upgrade in the latest ultrasound machines. They didn’t just need any machine. They wanted to properly invest in the best system to put an end to all the stress. What they needed was:
- High-quality imaging
- Consistent, reliable results
- Ease of use for all their staff
After a lot of research, they got the Philips Ultrasound probes. They chose a range of probes, including linear, curvilinear, and transvaginal types, to cover various imaging needs.
First, the radiology team was trained on the new system and transducers. The transition was smooth, with staff quickly adapting to this change.
The results were even better. In 3 months:
- They improved their diagnostic accuracy.
- They were able to reduce scanning times and interpreting results.
- The decision making was faster.
- Patients were satisfied given the shortened wait times and comfortable experience.
- The hospital was handling a variety of cases from routine scans to obstetrics imaging at the same time.
By upgrading to a faster and better system of Philips Ultrasound, the hospital was able to serve the patients with the quality they deserved.
FAQs
What do the numbers on an ultrasound mean?
Usually, the numbers on ultrasound scan or screen have nothing to do with your health. They indicate the hospital reference number, patient identification, or sometimes, technical settings.
What is a hockey stick probe?
A Hockey stick ultrasound probe is a small but one of the high-frequency transducers. It is named so due to its hockey-like shape, used for imaging small or hard-to-reach areas like peripheral nerves and tendons.
What is the maximum ultrasound frequency range?
Ultrasound frequencies generally range from 2 MHz to 18 MHz. Lower frequencies (2-5 MHz) are used for deeper imaging, like the abdomen, while higher frequencies (10-18 MHz) are used for superficial imaging, like muscles or tendons
How to hold an ultrasound probe?
Hold the ultrasound probe like a pen, with your thumb and fingers wrapped around it comfortably. Keep your wrist relaxed, and apply gentle pressure to ensure good contact with the skin. The orientation of the probe should match the desired direction on the screen.
How often should I replace my ultrasound transducer?
You should replace your ultrasound transducer when it shows signs of wear, like image quality degradation, physical damage, or if it fails safety tests. Regular maintenance checks will help you determine when it's time for a new one.
How are curved and linear ultrasound probes different?
A linear ultrasound probe has a straight edge and is used for more detailed imaging, like vascular scans. A curved probe has a more rounded shape and works perfectly when a wider field of view is required.
What should I do if my transducer isn’t working properly?
Check the cable for any visible damage. Clean the probe. Ensure it's connected securely.
If the problem persists, contact a service technician for a thorough inspection and repair.
