Non-contact Ultrasonic Scanner

I'm looking for non-contact ultrasonic scanning system for
3D imagining. I want to make 3D image of bones by means of auto scanning.
0.1mm resolution can be allowd.
Please help me to find non-contact ultrasonic scanning system.
Any comment will be appriciated.
Thank you!

Dear Sir,

little time ago we made a study, where we examinated the possibilities of enhancing medical imaging
by the use of tomographic methods. For this we builted up a experimental setup, where we scanned
a test object, exposed in a water tank by different directions using a normal 7,5 MHz medical scanner
(a linear array). With the reference of angular direction and position of the test object in correspon-
dence to the scanner we calculated a new image by tomographic methods.
Thus we obtaned a much higher aperture, minimizing speckle and other ultrasonic artefacts.
The test object was a Agar-Agar-phantom with embedded small kidney stones.
As you can see in our sample image, even the smallest stones are now visible.

As I could not attach the image by the form of the NDT.net forum (it is not possible to attach a simple
file) I will send it by a separate e-mail.
I will send the image also to everyone peron, which is interested in.

If you has interest in a cooperation for building up a ultrasonic tomography system following
your special needs, don`t hesitate to contact me again.

Best regards,

Dipl.-Ing. Martin Heinz.

If you can accept, that your bone will be measured in water and measuring time of about 30 second - 1 minute (for each side of the bone) - we can sell you such scanner.
Resolution will be probably even higher (0.01mm are possible).

The price will be 27,000 Euro. It is possible to make such a scanner working very quickly (in real time), but the price for the first device must be higher (about 40,000 Euro)

Conformable wedge transducer

The conformability is obtained with a flexible membrane filled with water between the transducer and

Lyft™: Pulsed Eddy Current Reinvented

PEC Reinvented—CUI Programs Redefined Corrosion under insulation (CUI) is possibly the greatest u
...
nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
