Tracked Ultrasound Probes

Hey Guys!
I just saw this video: https://www.youtube.com/watch?v=xmQG3b1I9Fs

First of all I wanted to ask you, if you know more Systems like that, where they track the exact position of the Ultrasound probe ? So far I have only seen Probes, where the position in one direction is tracked by a wheel.

Second I couldnt find much informations for the Camus3D System, its clear how they track the probe, but how do they track the Position of the tested part? Is there any information or paper that describes that?

Thank You!

Hi Gian-Alessio,

I am aware of another similar system which uses a stereoscopic camera for tracking the position of a probe and map a live C-Scan image. You can find the complete technical paper here:


This system is based on Zetec's TOPAZ PA UT platform and Northern Digital's Polaris Vega camera.

Enjoy the read!

Airborne ultrasound encoder for the mechanics free encoded XY scanning on the flat and curved surfaces is portable and field field proven for more than 20 years already, refer for example to:



there is a number of retro-videos available here


under <C-Scan> and <Weld Inspection Tabs> - there are more than 1000 ISONIC 2006 units are still in use around the Globe, mainly for corrosion mapping and SRUT GW inspection but before PA era they were used for the weld inspection and recording intensively

Since more than 3 years ago we have solution based on the new platform for ISONIC 3500 series instruments - refer to


It may work with the conventional and PA probes and may be connected to the instrument through USB cable or directly to incremental encoder terminal, the operation is very simple, the main applications are o-deg inspection (corrosion mapping or flaw detection) and SRUT GW inspection, some videos may be found here


under <C-Scan> tab, the links to the videos are:


100% raw data recording is provided along with the imaging

I remember that about 30years ago we got from UK a brochure about a system called SeeScan - today it is sold by TÜV Rheinland, see https://www.tuv.com/content-media-files/master-content/services/industrial-services/1303-tuv-rheinland-corrosion-mapping-(seescan%C2%AE)/tuv-rheinland-flyer-ndt-corrosion-mapping-en.pdf
It was originally developed by AEA in UK, and it seemed that it went through different companies, e.g. check this posting from 2004: https://www.ndt.net/forum/thread.php?msgID=20739%2320739. I remember that i had a flyer from Sonomatics, who sold the system - just check here, it is still available: http://www.vsonomatic.com/index.php?page=services-and-applications&objectid=282.

Another UK development came from NDT Consultants LTD called FreeScan, They withdrew it from their homepage as a product, but it still mentioned. I found a Facebook post: https://www.facebook.com/ndtconsultantsltdcoventry/photos/a.467281343377028/469834879788341/?type=3. It was ready to use with an Omniscan with plug & play. Only a small reflective dot had to be placed on the array probe, and optical system located the probe and the scan software of the Omniscan just used the FreeScan position data as indexer data to display large c-Scans.

DolphiCam also offered a tracking system with Metronor

CNDE proposed a generic scanner (GenScan) http://faculty.washington.edu/scottcs/NSF/2014/CNDE.pdf

The Sonotron Isonic solution is mentioned above, based on acoustic triangulation. It is rather long on the market, I know it from 2002 when we bought a first system.

There had been several systems based on triangulation on the market, already in the late 1980ties/early 1990ies, i had a long time a flyer of an American system in my desk, don't remember the brand anymore. There had been system on the market using optical triangulation with IR diodes on the probe, I guess phoenix NDT in Britain offered an electromagnetic triangulation solution.

There had been also solutions developed using tracking systems originally developed for whiteboards to transfer the pen moves directly into the PC (also optical or electromagnetic tracking. Also systems derived from Virtual Reality systems, there used to track VR goggles

Also a system like this <https://www.ndigital.com/medical/products/polaris-vega/> had been adapted

Boeing proposed some years ago AUNDI - Autonomous NDE and the Rover was tracked b several aerial tracking cameras - see e.g. https://www.ndt.net/article/aero2013/content/papers/60_Georgeson_Rev2.pdf

Like the Boeing installation also the TECNATOM Product WiiPA is a rather big installation to track a human inspector while scanning big parts: see http://tecnatom-ndt.com/wp-content/uploads/2014/12/TE_WiiPA_brochure_1.pdf

That’s for short what I remember fitting your question.

Hi Gian-Alessio.
Another probe tracking system that was on the market for a while was the ShaftScan system developed in Australia. This was a terrific system for inspection large diameter shafts and axles, but is no longer available, as far as I am aware. This system used a video camera in a manner similar to SeeScan.
I designed a tracking system for a client, also for shafts, using a rotary and a string pull linear encoder to track the probe radially, rather than X-Y. It was never commercialized. I also designed an X-Y tracker using air borne ultrasound for another client, also never commercialized. This was used for inspecting off-road tyres.
If you are a bit handy with making things, it is a fun project to make a probe tracker, and with some work, the positioning can be quite accurate.

Product Spotlight


Pulse thermography is a non-contact test method that is ideal for the characterization of thin fil
ms and coatings or the detection of defects. With a remarquable short test time and a high detection sensitivity, the Telops TESTD-PT is the perfect tool for non- destructive testing. With such high frame rates, it is even possible to investigate highly conductive or diffusive materials.

NEW! The PragmaPro Instrument Platform

The PragmaPro is based on a modular cartridge technology and supports various NDT instrument modal
ities such as UT, PAUT, ECT and many more. This new platform is based on a machined, powder-coated aluminum frame for shock-proofness, best sealing qualities and maximum heat dissipation. This is practical to extend the outdoor temperature range and/or to extend the power injected in the transducers. The PragmaPro is aiming at a very wide range of applications, such as weld scanning, corrosion mapping and composite testing.

Conformable wedge transducer

The conformability is obtained with a flexible membrane filled with water between the transducer and
the inspected component. The coupling between the membrane and the component requires a small quantity of water or couplant. The conformable wedge combines the acoustic performance of immersion technique with good coupling and low attenuation.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
